High score bounty!! Exception issue with local connection

In the command prompt, ipconfig all to check the mask of your machine, whether the gateway IP and DNS are filled in correctly, this is very important!

Then see if the IP is available

Check whether the gateway can ping through, and if so, ping DNS

Look at the returned result, if it is also passed, rebuild the arp cache table, arp -d If it is a local network configuration problem, reset the winsock directory: netsh winsock reset

If it still doesn't work, it may be a problem with the NIC driver, remove the NIC driver, and then reinstall the NIC driver

Whether you are Netcom or Telecom, if Netcom brings broadband to the world, it would be good. Local connections don't care about it.

The IP cannot be changed when an IP is specified on the connection cable.

Check your computer's configuration.

It's strange, how can you ask questions at the moment, you don't say it too clearly. It's very good, or not at all, or the kind of situation where you can only get on QQ.

Personally, I think you're going to have a hard time getting in. That's how I usually do it. Disconnect first.

While connected, restart the computer if it doesn't work. in the connection. If it still doesn't work, you have to analyze whether it is a software problem or a network card problem.

You can next a dialing software, yes, the Internet Star Dialer software can automatically check for problems, this software is very easy to operate.

1) If it is a problem with the broadband itself, first directly connect the broadband network cable to test the roll, if it is a broadband problem, contact broadband customer service to solve it.

2) If it's a problem with the router, if it can be used originally, it can't be used for the time being, my own practice is to cut off the router bend with the source plugged in, and I'll take a look. After there is a factory reset, it can be used from the new settings (this is on the premise that the physical connection is correct).

If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.

3) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

4) If you turn off the wireless switch, just turn it on, if it is a wireless connected by software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

5) If you have any questions, please ask me.

1. The notebook with the problem, if you determine the network IP address or something, then you uninstall the network card driver, refresh it, let it automatically install the network card driver, and see if it can go to the Internet normally. Sometimes the network card driver has a small fork and can be reinstalled.

2. If it doesn't work, then it is recommended to reinstall the system, and it is also possible that there is a problem with this module of the system's network, and the reinstallation system can sometimes be solved.

3. If the reinstallation system still doesn't work, then you have to consider whether there is a problem with the wireless network card or wired network card of the notebook, which is a hardware failure and can only be repaired, and cannot be solved by software debugging.

As for which problem it is, you need to check it one by one. I met the problem of renting here, and I also troubled the problem step by step and then solved it.
