1.
Enter the network connection property interface, select Internet Protocol version IPv4, and select automatic acquisition of IP address and DNS server address in the general property interface. The detailed steps are as follows:
1. Click the start button, find the windows system folder from the start menu, and enter, as shown in the figure below
2. . You see if your ADSL is set as a shared connection. In attributes. In the last item. 2 You see if your computer office or network is connected. 3 The general situation is that each computer can not set a gateway. The second computer gateway is set to the IP of each computer. You can have a look. 4 You may have made a mistake in setting the DNS in TCP / IP protocol or forgot to write it
it's better to call it automatically. If DNS is not allowed, the gateway is also problematic. It's OK after a day or a certain period of time. If the local gateway can't access it temporarily, it's useless to do anything````

3. You can change a computer to visit the same page to see what the reason is, is it the problem of the website itself, or your computer problem, if it is the problem of the website, then there is no way, can only wait for the website to repair. If it's a problem with your own computer, you can first check whether the DNS server of your own computer is filled in incorrectly. The specific operations are: network connection - properties - internet protocol (TCP / IP) - IP address. Check whether the settings are wrong, or whether the DNS server of Telecom is filled in incorrectly, resulting in the inability to access these websites. If there is no problem, just call the telecom customer service directly and consult.
4. 1 If the router is used, first disconnect the router single dial test
[2] if there is a modem device, you need to pay attention to whether the device is overheated. You can turn it off for a few minutes and try to restart it again
[3] if the program is disconnected when running alone (more than when playing games), it is recommended to restart the computer to try or re install the program
[4] if the whole network is disconnected, please check whether the access line and the network line are loose or in poor contact, and try to plug the line again;

Solutions and steps for router to diagnose DNS root domain name resolution failure:
method 1
1. First, open "360 security guard", select "function complete" at the top of the page, then click "my tools", and click the left mouse button, as shown in the figure
6. Nothing. It'll be OK after a while
7. Disable it, then enable it again, or fix it. There should be no problem. Then Ping the network.
8. Restart to see if it doesn't work
9. 1、 Use NSLOOKUP to judge whether it is really DNS resolution failure
1. Confirm that the system is Windows 2000 and Windows XP or above, and then enter the command line mode by "start run enter CMD"
2. Enter the NSLOOKUP command and press enter to enter the DNS resolution query interface
3. The DNS server address used by the current system will be displayed in the command line window. For example, the DNS server IP of Xiaobian is 118.123.8.174
4,
next, enter the domain name corresponding to the site you cannot access. For example, small input http://www.www.51web.com If you can't access it, then DNS resolution should not work normally
we will receive the prompt message of DNS request timed out, timeout was 2 seconds. This shows that our computer does have DNS resolution
failure. If DNS resolution is normal, the correct IP address will be fed back
2. Check whether the DNS server works normally
1. Confirm that your system is Windows 2000 and Windows XP or above, and then enter the command line mode by "start run enter CMD"
2. Enter ipconfig / all to query the network parameters
3,
in the ipconfig / all display information, we can see a place that says DNS servers, which is our DNS server address. For example,
118.123.8.174. It can be seen from this address that it is an external network address. If there is a resolution error when using the external DNS, we can change another DNS server address to solve the problem
4. If the internal network address of your company is displayed in the DNS server, then the DNS resolution of your company is completed by the internal DNS server of your company. At this time, we need to check the DNS server and perform NSLOOKUP operation on the DNS server to see if it can be resolved normally. Generally speaking,
problems can also be solved to solve DNS service failures on DNS servers
3. Clear DNS cache information
when a computer accesses a domain name, it is not always necessary to ask the DNS server for help. Generally speaking, after the resolution is completed, the resolution entry will be saved in the DNS cache list of the computer. If the DNS resolution changes at this time, because the DNS cache list information has not changed, When the computer accesses the domain name, it still won't connect to the DNS server to obtain the latest resolution information, and it will resolve according to the cache corresponding relationship saved on its own computer, which will lead to
current DNS resolution failure. This can be solved by the clear cache command
1. Enter the command line mode through start run enter CMD
2. Execute the ipconfig / flushdns command, and when the prompt "successfully flushed the DNS resolver cache" appears, it indicates that the cache information of the current computer and the cache information have been successfully cleared
3. When you visit the domain name next, you will get the latest resolution address from the DNS server, and there will be no resolution failure caused by one bit cache< Modifying hosts file is to modify the corresponding relationship of DNS resolution in hosts file, so as to achieve the correct resolution purpose. Because when the local computer accesses a domain name, it will first view the
host file in the local system, and the resolution relationship in the hosts file takes precedence over the resolution relationship on the DNS server. In this way, we can do it by adding parsing entries to the hosts file
1. Find the hosts file, file path: C: & # 92; windows\ system32\ drivers\ Etc directory to find the hosts file
2. Double click the hosts file and select Notepad to open it
3. Add the entry you want to do DNS resolution to the hosts file, format: IP address domain name, such as 192.168.1.1 Century Oriental virtual machine rental
4. After setting and saving, you can access it.
1. Confirm that the system is Windows 2000 and Windows XP or above, and then enter the command line mode by "start run enter CMD"
2. Enter the NSLOOKUP command and press enter to enter the DNS resolution query interface

Take tplink r4149 as an example:
1, browser input router management IP, default 192.168.1.1, enter
2. Enter the router administrator account and password, and click OK. The default is admin
3. Click network settings -- Wan settings, re-enter the correct DNS server address, and click save
remarks: the DNS server address can be obtained by calling the local ISP. If it is not available for the time being, it can be set to 8.8.8.8 and 114.114.114.114
China Telecom provides the best quality network communication service. At present, Anhui Telecom has a privilege package for examinees, with a discount of 1 call fee, 9 yuan for 99 yuan. It is recommended to inquire directly through Anhui Telecom Business Hall or entity business hall< br />
