    Connection setting conditions

    1 the cat or home cable must be connected to the WAN port of the router

    2 when configuring routing, you must use wired connection routing LAN port

    after entering the management page

    1 LAN port setting to open the DHCP function

    2 WAN port WAN port setting to set the Internet access mode as PPPoE mode, input the user name and password given by China Telecom or China Unicom, dial up the network, and change the connection mode to automatic connection

    3 wireless setting SSID name optional; Because there is a mobile phone or tablet Internet, the channel 6 mode is 11gonly20mhz for safety; Encryption method wpa-psk / wpa2-psk, fill in the password

    3. Sometimes when the computer is connected to the Internet, it will be prompted that it has been successfully connected, but it is unable to access the Internet normally. If the router is used to access the Internet, it is the setting problem of the router. If the network cable is directly connected, it is the setting problem of the computer network
    1. If the computer is connected to the Internet through a router and shows that it is connected but unable to access the Internet, the following steps can be taken to solve the problem. The following is an example of TP-LINK wr740n wireless router

    2. First, make sure that all the network connections of the router are correct. If you are not sure, check whether all the connections of the router are correct in the way shown in the router manual, If all connections are correct, then proceed to the next step
    3, turn over the router, check and record the management login IP, user name and password on the bottom nameplate; The management IP is generally 192.168.0.1 or 192.168.1.1; The user name and password are both admin by default, which is subject to the name plate identification
    4. Open the browser, enter the management IP address just recorded in the address bar, enter the user name and password in the pop-up login window, and click OK to log in to the router management interface
    5. After entering the router management interface, click "network parameters" in the left navigation bar, First, check whether the WAN port is set correctly. If you are using dial-up Internet, you need to check whether the broadband account and password are correct; If you are using static IP, you need to check whether the IP address, gateway and DNS information are accurate

    6. After setting, click the "running status" in the navigation bar to check whether there is network data flow. If there is data flow change, it indicates that the router networking is successful. At this time, you can try to connect the router to the Internet with a computer to solve the problem; If there is no data flow, there are two possibilities. One is that the broadband account in the router is not set correctly and cannot dial normally. Check the router account setting again to solve the problem; Another problem is the network itself. At this time, we need to contact the network operator to solve the problem

    end. If the computer is directly connected to the broadband Internet,

    1, if the computer is directly connected to the broadband, but can not access the Internet, this is generally caused by DNS problems. Next, take Windows 7 as an example to introce the method of repairing DNS. First enter "network and sharing center" → "change adapter settings"
    2, double-click "local connection", select "Internet Protocol version 4" and click "properties", enter the TCP / IP protocol properties window
    3, select "use the following DNS server address" in the TCP / IP protocol properties window, and enter the correct DNS address provided by the network operator, After entering, click "OK"
    4. If you still can't access the Internet normally after entering the DNS address provided by the network operator, you can use the free DNS resolution server address 8.8.8.8 and 8.8.4.4 provided by Google
    5. Through the above settings, if you still can't access the Internet normally, it's generally a network problem. Please contact the network operator directly, Operators help solve problems
    4. This phenomenon is caused by three reasons: first, the responsibility of the operator (transmission and switching network failure): the operator must ensure that the signal quality (bandwidth, bit error rate, signal to clutter ratio, transmission rate, signal level, input and output impedance, signal stability, input and output impedance stability) to the user meet the national standards; Specific telephone: Telecom 10000 Netcom 10060 2: user (responsibility) the following factors will lead to your current status. If there is no problem with the above operators, the next is your user's own problem; If you don't have the following problems, you can call the operator directly and ask the operator to tell you about the relevant matters of the operator. Copyright statement: the answer is harmonious original, no one can embezzle! Three: website problems: 1: the website server is unstable; 2: The software of the website is unstable; 3: The quality of website operation and maintenance is low; Can not timely troubleshooting; For example: it's good to go to other websites, but one website is especially bad. This is the problem of the website itself, which has nothing to do with the operators and users. Copyright statement: the answer is harmonious original, no one can embezzle! The user needs to check the part: 1: power supply 1.1 use a multimeter to check whether the power supply is stable? 1.2 is the AC voltage fluctuation within the allowable range? Does it exceed 5% of rated voltage? Is the ripple coefficient of 1.3a/d power supply (checked by millivoltmeter) qualified? 1.4 is the temperature rise of the power supply abnormal? 1.5 whether the voltage stabilizing characteristics meet the technical specifications? 1.6 under 1.5 rated load, whether the voltage stabilizing characteristics and ripple coefficient meet the technical specifications? 1.7 when replacing a large fan, does your power capacity meet the requirements? 1.8 the power supply of general auxiliary equipment (router, network switch, cat, etc.) is rectifier power supply, which has no voltage stabilizing function. The ripple coefficient is large (which may be caused by dry filter capacitor), and the load capacity is poor; If the equipment cannot work e to heating, special attention should be paid to the monitoring ring operation. 1.9 e to the over-voltage of the equipment (like feeding a child, too much can last), low voltage (like feeding a child, too little will lead to malnutrition), large voltage fluctuation (like feeding a child, too much to eat, too much to eat), over-current and heating, the overheating protection action will be switched out of fault and the equipment will be out of operation (that is, slow, delayed Repeat start, delay, drop line, interrupt, break line, automatic shutdown, crash, etc; 1.10 whether the over-current protection and over heat protection of power supply operate correctly? Is the movement sensitive? Do you refuse to operate or misoperate? Copyright statement: the answer is harmonious original, no one can embezzle! ★ 2: check the network cable and crystal head (R45): 2.1 whether the crystal head and seat are inserted (loose)? 2.2 is the contact good? What is the contact resistance? 2.3 is there any ash deposit? Is it oxidized? 2.4 is the mechanical locking between crystal head and base locked? 2.5 is the locking firm? 2.6 is the network cable tightly pressed and in good contact with the crystal head? 2.7 the line to line insulation resistance of network lines (using a 100V megger) shall be greater than 20 megohm. Copyright statement: the answer is harmonious original, no one can embezzle! 3: lightning protection, grounding: grounding is mainly to protect the safety of people and equipment! Lightning will burn the network card; When serious, it can cause fire and casualties! Multi point grounding, repeated grounding and nearby grounding are the principles; Grounding is divided into protective grounding, shielding grounding and working grounding; Static electricity is the main cause of blue screen crash! I use a noise meter to test that the noise voltage is more than 6000 times of the signal when it is not grounded. If you are not grounded, can your equipment work with such a high noise? Grounding is the most basic requirement for it, especially for analog devices and digital circuits. Interference from all aspects can be eliminated or eliminated through grounding. External interference and coupling between local and local wiring can be eliminated and eliminated. Equipment grounding and shielding work should be done well. Many interference comes from poor shielding and poor grounding, Many people only work on the software, and many interferences are caused by poor grounding or no grounding. This kind of fault is very easy to occur and easily ignored by many people. Many equipment damage is directly related to grounding. No grounding or poor grounding will lead to inter symbol interference, bit error, delay, packet loss, interruption, disconnection (disconnection, interruption), crash, card Automatic shutdown, repeated startup, repeated startup, frequent restart (or repeated connection) and other phenomena. There must be more than two grounding electrodes for grounding, and the interval between each grounding electrode shall be at least 10 meters. The grounding wire from the grounding electrode to the machine room shall not have any joint. Soft copper wire with a cross section of not less than 25 square mm shall be introced into the bus bar of the machine room (no joint is allowed in the middle), and the grounding wire shall be symmetrically connected with the Faraday network to facilitate the diversion of current, The connection point with the bus bar shall be coated with silver powder conctive paste, the cross section of the grounding wire from each equipment to the bus bar (independent) shall not be less than 4 square meters of multi strand soft copper wire, and the grounding resistance of the bus bar to each grounding electrode shall be less than 5 ohm (the smaller the better). At least twice a year, the grounding instrument (more than 2.5 level grounding instrument measurement, and the instrument is within the inspection period) shall be used for inspection. When checking the grounding electrode, it is strictly forbidden to do it in thunderstorm weather. It is strictly forbidden to use the n-zero line of water pipe and power line as grounding; That is, independent grounding device. The line of each equipment shall be connected to the bus bar of the machine room independently. It is strictly forbidden to connect the bus bar in series. I can say subjectively: whether you are an indivial user or a collective user of a large computer room, you are not grounded at all. Copyright statement: the answer is harmonious original, no one can embezzle! 4: Bandwidth: the bandwidth from operators to users is very important. Without enough bandwidth, enough data traffic cannot be guaranteed; It is impossible for computers to get on the Internet smoothly; The bandwidth mentioned above refers to the bandwidth of the whole process. Like on the expressway, there is such a wide bandwidth that there can be no fluctuation in the whole process; A little fluctuation in the whole process will affect the network speed; The user has the right to ask the operator (test with sweeper) for protection; 5: Signal to noise ratio (signal to noise ratio, which can be understood as signal purity) is small, the useful signal is covered by the noisy spurious signal (especially the inter symbol interference), so that the way to receive the signal can not correctly extract the useful signal from the noisy signal, and the judgment circuit can not correctly judge the code element, which will lead to error code Serious bit error is packet loss, serious packet loss is the cause of delay, and serious delay is line dropping (slow, delay, repeated start, line dropping, delay, line dropping, interruption, line breaking, automatic shutdown, crash, etc.). Use a noise meter or level meter to measure whether the noise level is within the allowable range, Or use oscilloscope to observe whether there is stray signal? Is there inter symbol interference? Take measures to eliminate it. The signal to clutter ratio should be more than 60dB. Test (observe) with sweep frequency instrument and oscilloscope. This indicator is to ensure that the road is smooth and barrier free. There is such a wide road, but also the whole process barrier free. Copyright statement: the answer is harmonious original, no one can embezzle! 6: matching: matching includes level matching and impedance matching (test with level meter and signal generator). 6.1 level matching: the received signal should not be too low. When it is too low, it can not reach the threshold level required by the receiving Road, and the equipment can not work normally; If the level is too high, the front-end circuit will be saturated or burned out. If the receiving level fluctuates near the receiving threshold, the computer will restart frequently; Therefore, receiving level adjustment is very important. Use level meter or oscilloscope frequently in operation to monitor and adjust the receiving level at the connection within the appropriate range. According to the instruction, monitor the adjustment with a level meter. 6.2: impedance matching: the connection point must match the impedance relatively. If the input and output impedance do not match, it will lead to reflection attenuation, and no matter how strong the signal is, it will not work normally. Copyright statement: the answer is harmonious original, no one can embezzle! 7: optimize the network structure, people will generate garbage when they turn on the computer to access the Internet, just like eating, if they don't clean the table, wash the dishes, and clean the stove, they will generate computer garbage, and the computer will graally show slow, card, delay, repeated startup, offline and other faults; Therefore, I recommend using some small tools: such as super rabbit, optimization master, Lu master or 360, etc; Develop a good habit of cleaning up rubbish before going offline. 7.1: timely removal of garbage fragments and ie cache generated by the Internet: as long as you use the computer, garbage will be generated. If you don't clean it in time, it will accumulate more and more. If you don't clean it for a long time, it will make the running space of C disk smaller and smaller and disorderly. Finally, it will slow down graally until it crashes; Therefore, regular sorting and running C disk can keep the computer running speed
    7.2: synchronize the ADSL device first: power off the device and restart it. Copyright statement: the answer is harmonious original, no one can embezzle! 8: software setting and configuration 8.1: Download common software from large official websites as far as possible. Do not install 3, informal software, P2P (resource occupying) software, and uncommon software. Turn off all unnecessary network connections and startup items, such as Thunderbolt, BT, donkey, etc; Do not put the non running software in the running C disk; Update patches in real time. Game software should be downloaded from regular large websites. Pay attention to whether the software is stable. Immature and unstable software will lead to slow, card, crash and other failures, especially some popular game software. Some netizens have a strong response to this. Such software should be paid special attention to or deleted immediately; When downloading software, we should pay attention to the rogue software inserted into the critical computer security, at any time to clear. Many acceleration software are mostly with viruses or ad plug-ins, which occupy your disk resources. Some game software started, the game will be directly t off, after the unlimited drop, restart and other failures. Protocol: the protocol in the network should also match it, and mismatching will also cause some equipment failures. Software conflicts will also cause delay, card, slow, crash, offline, interruption and other issues. 8.2: antivirus software and firewall at least one valid genuine antivirus software, and often upgrade the virus library: proper firewall settings (not too much, too high, too low), will cause some web pages can not be opened; Virus can make the computer slow down, crash, drop line, card, repeat start and switch failure. Copyright statement: the answer is harmonious original, no one can embezzle! 9: temperature, humidity and temperature rise (the temperature is graally rising after starting up) with the extension of starting up time, the temperature of the main equipment and its auxiliary equipment (cat, router, network switch, etc.) will graally rise. If it can not be sent out quickly, it will change from delay to slow to offline to crash. 9.1: humidity: in rainy season or rainy days and areas with high humidity, the insulation between lines and devices is reced, and the signal level drops, resulting in inter symbol interference, bit error, delay, packet loss, interruption, and line dropping (short line)

    The reasons why the wireless network card cannot be detected on the desktop and the solutions are as follows:

    1. the desktop is not installed with a wireless network card. Please refer to the notes below for the viewing method. If the desktop is not equipped with a wireless network card, if you need to use WiFi function, you need to buy a wireless network card. At present, there are two kinds of wireless network cards for desktop computers in the market. One is PCI interface, which belongs to built-in type and needs to open the chassis of the host computer for installation; The other is USB interface, which belongs to external type, and can be directly inserted into the USB interface of desktop computer

    2. the wireless network card has been installed on the desktop computer, but it is disabled. You can enter the network connection interface to check whether the wireless network card has been enabled. If not, right-click the wireless network card and select the enable command

    3. the desktop has installed a wireless network card, but there is no wireless network card driver or the wireless network card driver does not match. Can download the driver wizard, automatically detect and download the network card driver, if the brand machine can also download the wireless network card driver on the official website

    4. < / OL >

      remarks: take win7 system as an example, the method to check whether the desktop computer has a wireless network card is as follows:

      1. right click the computer icon, and click properties to open the menu


    6. Hello, because I don't know what your specific situation is, I will list the possible situations as follows:
    1. IP is not set, the following is the solution
    1. Right click "my computer" and select "management" to open
    2. Select device manager and click to open network adapter
    3. Double click to open "console full screen video driver" to see if it is installed normally. If the yellow exclamation mark or question mark is displayed, re install it
    4. Check the "local connection" IP settings, click "properties" to open "Internet Protocol", change the manual settings to automatic IP acquisition, and finally click "OK" to complete the operation, and the computer can automatically connect to the network
    Second, the router may not be connected to the external network. The solution
    connect the network cable connected to the router directly to your machine to see if it can be connected. If it can show that the router has a problem, if it can't show that your network supplier has a problem

    Third, if the above methods can't solve it, Please go down to
    the diagnosis method of a single computer in the LAN is as follows:
    Step 1: first, determine whether a single computer can't access the Internet or all computers in the LAN can't access the Internet. If a single computer can't access the Internet, in Windows XP / 2000 operating system, click the start / all programs / Accessories / communication / network connection command in turn to open the "network connection" window (you can also right-click on the network neighborhood icon and select the "properties" command),
    Step 2: then check the status of "local connection". If the local connection icon is two small computers flashing, it will prompt "connected", which means that the line from the switch hub to the computer is normal, the network card can basically work normally, and the inability to access the Internet is caused by improper setting of the operating system or software restrictions. Use the ping command to Ping the remote host to see if it can ping. If it can ping, the network connection is normal. Then check the firewall settings and proxy server settings in the computer
    Step 3: if Ping does not work, it may be a network protocol configuration problem. Check the configuration of IP address, gateway and DNS
    Step 4: if the local connection icon in the "network connection" window is gray, it means that the local connection (network card) is disabled. At this time, just double-click the local connection icon to enable it again
    Step 5: if the local connection icon in the "network connection" window prompts "local cable has been pulled out", it indicates that one end of the network cable connector from the switch or hub to the subscriber network card is loose or there is a problem with the network cable. Then check whether the network cable is in good contact. If it is in good contact, check the network cable

    if the fault persists, it is recommended to check and kill the Trojan horse first and try to repair the system<

    it is recommended that you download malicious software and Trojan horse killing tool windows cleaning assistant to check and kill malicious software and Trojan horse:
    download website:
    after downloading and installing, first upgrade to the latest version, then exit normal mode and restart, press F8 to enter safe mode. Open the software, click "system scan", select all the scanning results, and then click "execute clean" button. If the software prompts you whether to "backup", select "yes" (backup is to prevent the occurrence of cleaning errors, and delete the backup if there is no exception after cleaning), Operate according to the prompt (the software can also check and kill in normal mode)

    1. Press F8 to leave the advanced option open. Select "last correct configuration" and press enter to repair
    2. Press F8 to enter the safe mode and then exit. Select restart or shutdown to enter the normal mode (repair the registry)
    3. If the fault still exists, please restore it with the system restore provided by the system, and repair it when you don't have this fault (or use the restore software to restore the system)
    4. If the fault persists, use the system disk to repair, open the command prompt, enter SFC / scan, enter (there is a space between SFC and / and insert the original system disk to repair the system, and the system will automatically compare the repair results
    5. If the fault persists, set the CD-ROM drive in BIOS as the first boot device, insert the original system installation disk, and press R to select "repair installation"
    6. If the fault persists, it is recommended to reload the operating system

    delete the original dial-up connection and try to re-establish it

    the DNS of local connection is not unified with that of wireless connection.
    7.

    There is no shortcut for broadband connection in the newly installed system. You can create one, the specific method is:

    1. Right click the network - properties, as shown in the following figure:

    5. Fill in the user name and password

    8. Hello
    if your desktop computer supports wireless connection, just connect to the wireless network and enter the wireless password to connect to the Internet. You can try again.
    9. mining Strategy:

    it's useless to hoard too many trees, as long as it's enough for you to use. Moreover, trees are a very cheap and easily available resource, and minerals must be accumulated step by step. Local tyrants have never said how many diamonds they have, not how many wood XD they have

    but we still need wood. I think you need at least one set of wood

    bring your tools and food. Just bring a torch and it's OK

    the best mining height is 11, which contains the most abundant minerals. If you don't know the height, you can download the basic integration package. These integration packages usually have a small map plug-in. The small map plug-in is in the upper right corner, and there is a value in it. If you don't know which is the height, you can look and jump to a box, That value will be + 1, and if you jump down, it will immediately be - 1.

    reach 11... It's very simple, dig the ladder = = if you don't know how to descend to 11, then I have no way

    the mining method developed by g-g-g is very effective, as you can know from your own experience,

    because you only have stone pickaxes, and many mineral stone pickaxes can't dig, so if you encounter iron, dig it down immediately, and then make a furnace on the spot to burn at least three irons to make an iron pickaxe

    when you are mining, you will encounter coal. Coal plus a group of wood you carry with you is a lot of torches

    the most important thing to be careful in mining is to step forward after you have finished digging one space, so as not to fall into the magma lake

    many people will encounter the problem of too many things on their bodies when they are digging underground. So before that, after you descend to the 11 grid platform, please dig a space like digging a hole in the ground. This space will serve as your base under the ground. There is a stove and several boxes in this base, and the stove and boxes also need to be locked

    the stove is used to burn iron, but please note here that iron is not burned as much as you dig, but when you need a pick to burn a few pieces of iron

    as for many unburned minerals, they are left to be taken to the ground after finishing work

    the most important point of a local tyrant is frugality. Many people use diamonds as pickaxes when they dig diamonds. This is a waste. They should use stone pickaxes to dig, and use iron pickaxes when they encounter things that stone pickaxes can't dig.
