1. < / UL > < H2 > 2. C2C trading on trading platform
< / UL > < H2 > official statement:
At present, there are many channels for domestic users to buy Ethereum. Here are some common channels:
< H2 > 1. Coincola is an over-the-counter trading platform for indivials to trade bitcoincoy Cola is affiliated to Hong Kong coincola limited, which is developed and operated by a professional international team, focusing on providing convenient and reliable blockchain services for global users. Coincola gathers global users and is committed to building a world-class blockchain asset platform
in coy cola, people from different countries can buy bitcoin with their own currency. The seller of the website publishes the advertisement of selling bitcoin, and explains the payment method and exchange rate. You can choose to trade directly online according to the content of the advertisement. Bitcoin is stored in Ke Ying Cola's Internet wallet. You can transfer bitcoin directly
2. How to buy eth
register the coincola account, and then click "buy" in the top menu of the home page to enter the advertisement list page
select the appropriate advertisement from the advertisement list and click "buy eth" to enter the transaction page
enter the amount of money to be purchased or the number of digital currency (please understand the message information of the other party, payment method, and transaction instructions of the platform before entering), click buy now, and the order confirmation pop up. After checking and confirming the information, click confirm purchase to enter the order page
in the chat box of the platform, you can inquire whether the other party is online according to the template statement, and make offline payment according to the collection information and collection method provided by the other party
after the completion of offline payment, click the mark that the payment has been completed at the first time (please complete this operation within 15 minutes at the beginning of placing an order, so as to avoid the payment cannot be recovered e to the cancellation of the order e to overtime), and then customize the input information in the chat box to confirm the payment and ask the seller to confirm the collection and release the digital currency
the progress bar in the top column shows that the goods have been received, indicating that the digital currency has arrived in the wallet. Make comments according to the seller's behavior, and click submit to complete the transaction
with the rapid increase in the number of trading platforms and competitive pressure, many trading platforms will have their own C2C trading. Here we take the relatively large ZB trading platform as an example to illustrate
What is C2C
C2C transaction is a customer to customer transaction, which is guaranteed by the transaction platform. There are many such platforms, such as: Fire coin, otcbtc, bitpai OTC, etc., which are guaranteed by the platform and traded between users. We can simply understand it as: our shopping situation on Taobao is the same as that. In case of dispute, the platform will arbitrate. As long as the transaction is carried out according to the normal process, the security of the transaction is guaranteed
2. ZB's C2C business
ZB platform has two choices: QC and usdt. The basic logic is the same. There are many usdt platforms. QC is the feature of ZB, EXX and other platforms. Here we focus on QC
< H2 > about QCQC is a token. At present, you may know more about usdt and bitcny. At present, there is a special area for QC transaction on ZB. Simply put, QC can buy all other digital currencies (BTC, ETH, EOS, etc.) on ZB. Therefore, after purchasing QC with RMB recharge, you can conct currency transaction on ZB station
The advantage of the < H2 > QC token is that the exchange ratio between the < H2 > < UL >and RMB is 1:1, which is easier to convert
purchasing other tokens with QC can be directly understood as purchasing RMB, and has an intuitive understanding of the currency price
it takes about half an hour to get to the account. It will take about two hours to get to the account in congestion
ZB platform is relatively reliable, and the reputation of ZB is still very good in the past
How to operate C2C of ZB < UL >log in to ZB trading platform and click "C2C trading" on the page
to get to the QC transaction page, you need to first bind your bank card. Then, in the buy QC interface, enter the quantity of QC you want to buy. At present, the ratio of QC to RMB is 1:1. Enter the purchase quantity and click "buy now"
after clicking "buy now", you will be prompted to complete the payment within 30 minutes. At the same time, payment information is generated. Please note that the payment must be made according to the prompt
business processing time 9:00-21:00. Non processing time orders will be processed at 9:00 the next day, and the payment will be completed within 24 hours after receiving the order
this means that the merchant you paid will transfer QC coin to your account within 24 hours. According to my experience, you can get to the account in 2 hours ring the day
< H2 > the following points should be paid attention to:1) make sure to use the newly bound bank card for transfer and payment
2) note information (that 6 digit) must fill in
3) do not use Alipay, WeChat and other transfers. p>
4) do not fill in the opposite account incorrectly
< UL >about 1-2 hours, you can check whether your QC has arrived in the financial center
after the account is received, you can trade in the "QC" zone of the "spot trading". You can choose the transaction you want to buy and buy the order
2. As a bitcoin trading platform, fire coin has won a round of 10 million RMB capital investment from Zhenge fund, Dai Zhikang, Sequoia Capital (shareholders of many global well-known companies such as apple and Alibaba). Fire coin implements strict risk control management and operates stably. As of the end of 2016, the accumulated turnover of fire currency reached 200 billion yuan
on September 15, 2017, huoyuan.com announced that registration and RMB recharge services will be suspended from now on, and all users will be informed before September 30 that they will stop trading. At the same time, all transactions of digital assets against RMB will be graally stopped before October 31. Fire money network said it will stop virtual currency trading on October 31, 2017. You can contact the fire coin net official consultation refund question

3. Solution
1. First, make sure that the ADSL modem dials normally or the physical link between the network cable directly entering the home and the switch is unobstructed. Because the IP automatically obtained by the network card is not cleared, when dialing again, the network card cannot obtain a new IP address, and 678 will be prompted. The operation method is: turn off the ADSL modem, enter the network connection of the control panel, right-click the local connection, and select disable, After 5 seconds, right-click local connection, select enable, and then open ADSL modem to dial; If you are a direct network cable user, you can disable the local connection, right-click to select the status after enabling the local connection, check whether the receiving and sending are normal, and check whether you can obtain a valid intranet IP (Telecom has no intranet IP, only limited to mobile fiber broadband)
2. If the first step is invalid, you can still disable the local connection (network card) when you turn off the ADSL modem, restart the computer, enable the local connection (network card), and then turn on the ADSL modem
3. If the above steps cannot be solved, check whether the network card light is on. If the power light is flashing, check the power supply and modem itself; If the outside line indicator light is still flashing, you can check the indoor line
4. If the network card light is normal, step 1 and step 2 cannot be solved, then lead the user to unload the network card driver and re install the network card driver. If the user XP system follows: knowledge number: 9973, how to set the ADSL dial-up connection method under WinXP to lead the user to create a dial-up connection, if the 98 system recommends that the user install the rasppoe software or ehernet300 software to connect
5. If the above operation is invalid, contact your local network provider to confirm the port
6. ADSL modem failure is the main reason. Maybe the router was not set up. The writer, ADSL, thought that the router was broken and bought a new one, but the result was the same. Later, he read the manual and realized that it was not just good to plug in the cable, but also need to set up. Take TP-LINK for example, first enter 192.168.1.1, then set up the wizard, fill in admin for both user name and password, click next, and choose the Internet access mode, Just fill in the relevant items, and pay attention that you don't need to dial in the future
7. If multiple computers use a router to access the Internet, try to remove the router and connect to Internet. If you can access the Internet smoothly, it means that the router is faulty. You should remove the router or replace it with a new one
8. If you are an annual ADSL user, if this happens ring use, it may be e to the phone. Please consult the customer service center. Some regions of China Telecom or China Unicom users, in the case of telephone arrears, can get through the phone, but can not access the Internet. At this time, it may also be telephone arrears, because some regions of the telecommunications department in the case of telephone arrears, not to stop the use of the phone, but to stop the use of the network
9. The lack of power supply of some brands of modems is also easy to cause error 678
10. If none of the above methods can solve your problem, you can try ADSL modem reset and try again by pressing two or three times
11. The damage of ADSL modem equipment can also cause error 678. Although it seems that ADSL modem works normally, the connection fails. The author encountered this kind of problem, and finally changed a new ADSL modem to solve the problem
12. The poor contact between the cat line and the distributor can also cause error 678. When the contact is poor, there is no problem in calling, and the broadband can be connected occasionally, but it is easy to drop the line or report error 678. The author is worried about this problem, and the cat has changed one, but later she accidentally reconnects the cat line, and it is OK. I hope it can help
13. Bad contact or damage of network card may also cause 678 error. Try to unplug and re insert or replace a new network card to solve the problem
if not, try deleting the broadband connection and creating a new one< [2]
14. Use Xunlei's game accelerator, and it will be 678 the next day. After repairing the LSP, the accelerator will be unloaded. When 678 appears, it is suggested to recall what software has been installed before and what settings have been changed.

4. There is no communication between the sending card and the receiving card. The LED terminal should be given private IP. You can ping to see the difference.
5. According to you, your IP address is automatically assigned to you by the school's DHCP server. As for the Ruijie client, I think it must be designed before the DHCP server when setting up the network. So you don't care about the client that doesn't ask for pain. My advice to you is to renew or update your NIC driver first, and then make sure that your NIC driver is normal. In addition, first uninstall the Ruijie client, I don't know if your school has set up the network card binding. After confirming that there is no problem with the NIC driver, set it to automatically obtain the IP address, and then install your Ruijie client. This broken software was easily won by the big brother in the dormitory when he was in college. I haven't paid the Internet fee... Even if the network card is bound, you can use it after modifying the parameters of the network card. So this charging software sucks. Do you understand? Some n-card drivers even conflict with Ruijie, which leads to high CPU utilization.
6. When using ADSL to access the Internet, we often encounter the phenomenon that the web page cannot be opened, the download is interrupted, or the online video and audio stream is interrupted, QQ is dropped, and the game is dropped. We might as well assume that the landlord is using ADSL to access the Internet. In fact, the reasons why other ways of Internet access are often offline are roughly the same as the following reasons. Now let's analyze the reasons for ADSL offline
first, the line problem
first, check the line at home to see if the connector in the house is connected properly, and whether the line passes through any interference source, such as air conditioner, refrigerator, TV, etc., and try to keep a certain distance from these electrical equipment. It can also replace the indoor lines with more anti-interference network cables. Make sure the wiring is connected correctly. After entering the home, the telephone line is connected to the junction box, and then separated to the voice separator, one line goes to the telephone, one line goes to the modem (the separator is marked). At the same time, ensure that the communication quality of the line is good without interference, and no other equipment that will cause line interference is connected. And check whether the junction box and crystal head have poor contact and whether they are wound in series with other wires. If possible, it's better to use standard telephone line and connect PC with twisted pair attached to ADSL modem. Line is one of the important factors for the quality of image access to the Internet. Signal interference sources such as radio transmitting tower, electric welding machine, tramcar or high-voltage power transformer within 100 meters from the user's cable can make the user offline receive clutter (copper clad steel wire has weak shielding and strong signal receiving ability), causing strong interference to the user's line. The interfered signal is usually the unshielded offline part, because the relay cable has a shielding layer, so the interference and influence are very small. If you use some shielded downlines in places with large interference, it will rece the speed instability or disconnection caused by interference. In addition, the power line should not be paralleled with the ADSL line, in order to avoid crosstalk, resulting in ADSL failure. In addition, there are many other factors that cause network instability, such as signal interference, software conflict. The mobile phone, which has a large radiation, must not be placed next to the ADSL modem, because the mobile phone will automatically find the network every few minutes. At this time, the strong electromagnetic interference is enough to cause the ADSL modem to cut off the current
Second, the network card problem
the network card is usually PCI network card or on-board network card. When you choose, you must choose the one with better quality, otherwise the quality of Internet access may be poor. 10m or 10m / 100M adaptive network card can be used. In addition, many machines share the Internet and use al network cards, which also causes conflicts, which is also worthy of attention. At this time, you should pull up the network card connecting to the LAN or other computers, and only use the network card connecting to ADSL to test the Internet. If the fault returns to normal, check whether there is any conflict between the two network cards
Third, ADSL modem or network card setting problem
now modem generally has two working modes, one is the normal mode of using dialing software, the other is the routing mode of automatic dialing. In normal mode, you don't need to set modem, just use the default mode. The routing mode needs to be set. Modem has its own flash memory, which can save the account and password box settings for automatic dialing. The most common method is to set the IP address of ADSL modem or DNS server incorrectly. Because for ADSL virtual dial-up users, there is no need to set the IP address, which can be automatically assigned. TCP / IP gateway generally does not need to be set. But set DNS must be set correctly, DNS address can be obtained from the local telecommunications department. In addition, TCP / IP settings are most likely to cause the situation of not being able to browse web pages. Generally, it is set to automatically obtain the IP address, but DNS must be filled in. Other default can be used
Fourth, ADSL modem synchronization abnormal problem
check whether your phone line and the ADSL connection are in poor contact, or there is a problem with the phone line, the poor quality of the phone is particularly prone to drop, but this problem is not easy to check, so be sure to use a good quality phone line. If it is suspected that the separator is broken or the ADSL modem is broken, try to directly connect the external line to the ADSL modem without using the separator. The connection between the separator and ADSL modem should not be too long, otherwise it cannot be synchronized. To eliminate the above situation, as long as the ADSL modem is restarted, the synchronization problem can be solved
fifth, operating system, virus problems
in addition to the above-mentioned line conditions, there are also computer system problems. For example, the legendary killer caused the LAN to drop. This problem occurs in a large area all over the country. The virus will affect the Internet cafes (LAN) of host agent and router agent. Legend killer is a destructive software that can cheat LAN by ARP and create virtual gateway address to collect login information of Legend game in LAN and analyze it to get user information. Workflow: first of all, broadcast local Mac to LAN by ARP Cheating, so that the workstation in LAN mistakenly thinks this machine is gateway. This process will cause the connection between LAN and Internet to be interrupted, When the user restarts the game and logs in the account, the account information will not be uploaded to the proxy server directly through the gateway, but will be uploaded to the legendary killer software which is carrying out ARP deception, Attack situation: LAN and Internet link speed suddenly slows down or even breaks down. Online games break off the link, and after logging in again, the server will be prompted that there is no corresponding response. It is suggested to check and kill the virus first; If you have the ability, re install the system; If the machine has two network cards, unload one network card; It is suggested that users who are not familiar with computers should not install all kinds of firewall software at will. Incorrect settings will cause unstable Internet access. Some operating systems may have compatibility problems with ADSL related components, so you can go to Microsoft to upgrade the system or repair the system. If possible, it can be reassembled. If there is a conflict in the software, try to find out the conflict software, uninstall it or solve it by other methods< (6) the firewall and IE browser are not set properly.
although ADSL is less likely to be attacked by hackers and viruses, it does not rule out the possibility, especially web viruses and worms. If the virus destroys ADSL related components, there will also be a disconnection phenomenon. If it can be determined that it has been damaged and attacked by the virus, and there is a disconnection phenomenon, it is necessary to check the installed firewall, proxy server software for sharing the Internet, Internet acceleration software, etc. after stopping running such software, it is necessary to test the Internet to see if the speed returns to normal. If the Internet is not stable, you can try to turn off the firewall first, test whether it is stable or not, and then set it accordingly. In addition, firewall or IE browser failure can also lead to normal connection, but can not open the web page< Seven, static problem
static is an important factor affecting ADSL, and the power supply in the home is generally not grounded, coupled with the interference of various electrical appliances (such as refrigerators, TVS), it is easy to cause static interference, resulting in frequent disconnection of ADSL in use, please lead the grounding terminal of the three core socket out of the wire and make a good grounding, which can generally solve the problem of disconnection. General solution: add grounding wire to solve the problem of disconnection< Eight, software conflict problem
there are two ways for ADSL to access the Internet: virtual dial-up and private line access. Now most of the ADSL of indivial users are virtual dial-up. PPPoE (point-to-point protocol over Ethernet) virtual dialing software has its own advantages and disadvantages. After many tests on different operating systems, if the operating system is Windows XP, it is recommended to use its own PPPoE dialing software, which has less current interruption and relatively improved stability. If you are using Windows me or 9x, you can use the following virtual dialing software -- enternet, winpoe, raspppoe. Among them, enternet is now more commonly used, and enternet 300 is suitable for Windows 9x; Enternet 500 is suitable for Windows 2000 / XP. When you have problems with one PPPoE dialing software, you may as well uninstall the software and use another PPPoE dialing software. Please be careful not to install multiple PPPoE software at the same time to avoid conflicts. Because the telephone line is the main way of broadband access, so we must set up a virtual channel. If several kinds of dial-up software are mixed, it will cause conflicts, resulting in network instability. If there is a conflict in the software, try to find out the conflict software, uninstall it or solve it by other methods. For example, some friends BT download will lead to network offline. It may take too many threads to download, resulting in disconnection
in addition, besides the above reasons for your own computer, the reasons for QQ and game offline may also be related to their own server restrictions and server attacks or failures Poor contact of network lines, most of them are loose plugs, some of them are disconnected
2. There are problems with the quality of network hardware, such as double glue cable, crystal head, separator, cat, router and network card. It is important that the quality of cat, router and network card is excellent
3. Pay attention to the heat dissipation of separator, cat and router
4. If the integrated network card is unstable, you can replace it with an independent network card to update the network card driver
5. XP is best to use the system's own dial-up program, 98 Internet dial-up tool software, raspppoe or winpoe can be selected. Note that only one kind of dial-up tool software can be installed in a computer, otherwise it will cause conflicts
6. Establish a new network connection
7. Reset the TCP / IP protocol
(1) start - connect to - show all connections - right click local connections - properties - General - click Internet Protocol (TCP / IP) - properties - select the following IP address (this is my IP address, your IP address, the network will tell you):
IP address: 192.168.0.2
subnet mask: 255.255.255.0
Default Gateway: 192.168.0.1
use the following DNS server address (my server address, ask your network provider):
preferred: 1.1.1
standby: 24.24.24
(2) right click broadband connection - properties - Network - select automatic IP address - OK
8. Users are too far away from the computer room, resulting in large line loss and interference
9. Although ADSL is less likely to be attacked by hackers and viruses, it does not rule out the possibility, especially web page viruses and worms. If the virus destroys ADSL related components, there will also be a disconnection phenomenon
10. The firewall and IE browser are not set correctly. Turn off the firewall first, test whether it is stable or not, and then set it accordingly. In addition, firewall or IE browser failure can also lead to normal connection, but can not open the web page.
first, the line problem

It is suggested to check and kill the virus first; If you have the ability, re install the system; If the machine has two network cards, unload one network card; It is suggested that users who are not familiar with computers should not install all kinds of firewall software at will. Incorrect settings will cause unstable Internet access. Some operating systems may have compatibility problems with ADSL related components, so you can go to Microsoft to upgrade the system or repair the system. If possible, it can be reassembled. If there is a conflict in the software, try to find out the conflict software, uninstall it or solve it by other methods< (6) the firewall and IE browser are not set properly.
although ADSL is less likely to be attacked by hackers and viruses, it does not rule out the possibility, especially web viruses and worms. If the virus destroys ADSL related components, there will also be a disconnection phenomenon. If it can be determined that it has been damaged and attacked by the virus, and there is a disconnection phenomenon, it is necessary to check the installed firewall, proxy server software for sharing the Internet, Internet acceleration software, etc. after stopping running such software, it is necessary to test the Internet to see if the speed returns to normal. If the Internet is not stable, you can try to turn off the firewall first, test whether it is stable or not, and then set it accordingly. In addition, firewall or IE browser failure can also lead to normal connection, but can not open the web page< Seven, static problem
static is an important factor affecting ADSL, and the power supply in the home is generally not grounded, coupled with the interference of various electrical appliances (such as refrigerators, TVS), it is easy to cause static interference, resulting in frequent disconnection of ADSL in use, please lead the grounding terminal of the three core socket out of the wire and make a good grounding, which can generally solve the problem of disconnection. General solution: add grounding wire to solve the problem of disconnection< Eight, software conflict problem
there are two ways for ADSL to access the Internet: virtual dial-up and private line access. Now most of the ADSL of indivial users are virtual dial-up. PPPoE (point-to-point protocol over Ethernet) virtual dialing software has its own advantages and disadvantages. After many tests on different operating systems, if the operating system is Windows XP, it is recommended to use its own PPPoE dialing software, which has less current interruption and relatively improved stability. If you are using Windows me or 9x, you can use the following virtual dialing software -- enternet, winpoe, raspppoe. Among them, enternet is now more commonly used, and enternet 300 is suitable for Windows 9x; Enternet 500 is suitable for Windows 2000 / XP. When you have problems with one PPPoE dialing software, you may as well uninstall the software and use another PPPoE dialing software. Please be careful not to install multiple PPPoE software at the same time to avoid conflicts. Because the telephone line is the main way of broadband access, so we must set up a virtual channel. If several kinds of dial-up software are mixed, it will cause conflicts, resulting in network instability. If there is a conflict in the software, try to find out the conflict software, uninstall it or solve it by other methods. For example, some friends BT download will lead to network offline. It may take too many threads to download, resulting in disconnection
in addition, besides the above reasons for your own computer, the reasons for QQ and game offline may also be related to their own server restrictions and server attacks or failures Poor contact of network lines, most of them are loose plugs, some of them are disconnected
2. There are problems with the quality of network hardware, such as double glue cable, crystal head, separator, cat, router and network card. It is important that the quality of cat, router and network card is excellent
3. Pay attention to the heat dissipation of separator, cat and router
4. If the integrated network card is unstable, you can replace it with an independent network card to update the network card driver
5. XP is best to use the system's own dial-up program, 98 Internet dial-up tool software, raspppoe or winpoe can be selected. Note that only one kind of dial-up tool software can be installed in a computer, otherwise it will cause conflicts
6. Establish a new network connection
7. Reset the TCP / IP protocol
(1) start - connect to - show all connections - right click local connections - properties - General - click Internet Protocol (TCP / IP) - properties - select the following IP address (this is my IP address, your IP address, the network will tell you):
IP address: 192.168.0.2
subnet mask: 255.255.255.0
Default Gateway: 192.168.0.1
use the following DNS server address (my server address, ask your network provider):
preferred: 1.1.1
standby: 24.24.24
(2) right click broadband connection - properties - Network - select automatic IP address - OK
8. Users are too far away from the computer room, resulting in large line loss and interference
9. Although ADSL is less likely to be attacked by hackers and viruses, it does not rule out the possibility, especially web page viruses and worms. If the virus destroys ADSL related components, there will also be a disconnection phenomenon
10. The firewall and IE browser are not set correctly. Turn off the firewall first, test whether it is stable or not, and then set it accordingly. In addition, firewall or IE browser failure can also lead to normal connection, but can not open the web page.
7. When using ADSL to access the Internet, we often encounter the phenomenon that the web page cannot be opened, the download is interrupted, or the online video and audio stream is interrupted, QQ is dropped, and the game is dropped. We might as well assume that the landlord is using ADSL to access the Internet. In fact, the reasons why other ways of Internet access are often offline are roughly the same as the following reasons. Now let's analyze the reasons for ADSL offline
first, the line problem
first, check the line at home to see if the connector in the house is connected properly, and whether the line passes through any interference source, such as air conditioner, refrigerator, TV, etc., and try to keep a certain distance from these electrical equipment. It can also replace the indoor lines with more anti-interference network cables. Make sure the wiring is connected correctly. After entering the home, the telephone line is connected to the junction box, and then separated to the voice separator, one line goes to the telephone, one line goes to the modem (the separator is marked). At the same time, ensure that the communication quality of the line is good without interference, and no other equipment that will cause line interference is connected. And check whether the junction box and crystal head have poor contact and whether they are wound in series with other wires. If possible, it's better to use standard telephone line and connect PC with twisted pair attached to ADSL modem. Line is one of the important factors for the quality of image access to the Internet. Signal interference sources such as radio transmitting tower, electric welding machine, tramcar or high-voltage power transformer within 100 meters from the user's cable can make the user offline receive clutter (copper clad steel wire has weak shielding and strong signal receiving ability), causing strong interference to the user's line. The interfered signal is usually the unshielded offline part, because the relay cable has a shielding layer, so the interference and influence are very small. If you use some shielded downlines in places with large interference, it will rece the speed instability or disconnection caused by interference. In addition, the power line should not be paralleled with the ADSL line, in order to avoid crosstalk, resulting in ADSL failure. In addition, there are many other factors that cause network instability, such as signal interference, software conflict. The mobile phone, which has a large radiation, must not be placed next to the ADSL modem, because the mobile phone will automatically find the network every few minutes. At this time, the strong electromagnetic interference is enough to cause the ADSL modem to cut off the current
Second, the network card problem
the network card is usually PCI network card or on-board network card. When you choose, you must choose the one with better quality, otherwise the quality of Internet access may be poor. 10m or 10m / 100M adaptive network card can be used. In addition, many machines share the Internet and use al network cards, which also causes conflicts, which is also worthy of attention. At this time, you should pull up the network card connecting to the LAN or other computers, and only use the network card connecting to ADSL to test the Internet. If the fault returns to normal, check whether there is any conflict between the two network cards
Third, ADSL modem or network card setting problem
now modem generally has two working modes, one is the normal mode of using dialing software, the other is the routing mode of automatic dialing. In normal mode, you don't need to set modem, just use the default mode. The routing mode needs to be set. Modem has its own flash memory, which can save the account and password box settings for automatic dialing. The most common method is to set the IP address of ADSL modem or DNS server incorrectly. Because for ADSL virtual dial-up users, there is no need to set the IP address, which can be automatically assigned. TCP / IP gateway generally does not need to be set. But set DNS must be set correctly, DNS address can be obtained from the local telecommunications department. In addition, TCP / IP settings are most likely to cause the situation of not being able to browse web pages. Generally, it is set to automatically obtain the IP address, but DNS must be filled in. Other default can be used
Fourth, ADSL modem synchronization abnormal problem
check whether your phone line and the ADSL connection are in poor contact, or there is a problem with the phone line, the poor quality of the phone is particularly prone to drop, but this problem is not easy to check, so be sure to use a good quality phone line. If it is suspected that the separator is broken or the ADSL modem is broken, try to directly connect the external line to the ADSL modem without using the separator. The connection between the separator and ADSL modem should not be too long, otherwise it cannot be synchronized. To eliminate the above situation, as long as the ADSL modem is restarted, the synchronization problem can be solved
fifth, operating system, virus problems
in addition to the above-mentioned line conditions, there are also computer system problems. For example, the legendary killer caused the LAN to drop. This problem occurs in a large area all over the country. The virus will affect the Internet cafes (LAN) of host agent and router agent. Legend killer is a destructive software that can cheat LAN by ARP and create virtual gateway address to collect login information of Legend game in LAN and analyze it to get user information. Workflow: first of all, broadcast local Mac to LAN by ARP Cheating, so that the workstation in LAN mistakenly thinks this machine is gateway. This process will cause the connection between LAN and Internet to be interrupted, When the user restarts the game and logs in the account, the account information will not be uploaded to the proxy server directly through the gateway, but will be uploaded to the legendary killer software which is carrying out ARP deception, Attack situation: LAN and Internet link speed suddenly slows down or even breaks down. Online games break off the link, and after logging in again, the server will be prompted that there is no corresponding response. It is suggested to check and kill the virus first; If you have the ability, re install the system; If the machine has two network cards, unload one network card; It is suggested that users who are not familiar with computers should not install all kinds of firewall software at will.

if this is not the case, the network in your area may be unstable, which is very common. Try to avoid the rush hours.

In this case, there may be an error in the DNS resolution of the computer, and the DNS needs to be replaced. The method is as follows:
1. There are many software to provide DNS replacement service. Here, take Tencent's computer manager as an example (the operation method of other software is roughly the same), open the software and switch the page to the [toolbox] page
9. Is this a router
please describe clearly
in general, under unknown conditions, take measures to restart the network device, and then re connect the mobile wifi
please describe clearly
in general, under unknown conditions, take measures to restart the network device, and then re connect the mobile wifi
10. You re-enter the user name and password on the broadband connection as follows!! Hehe, I used to be like this, that's how I solved it! Thank you ~ ~ if you are satisfied, please add points!
