You disconnect it, reconnect it, and then reboot it.

If you connect to a router, it shows that the connection is useless, and you must ensure that the router is connected to the network.

If you are using a router to access the Internet, if the computer is connected to the Internet through a router and it shows that it is connected but cannot access the Internet, you can follow the steps below to solve the problem, the following is to take the TP-Link WR740N wireless router as an example.

Make sure that all the network connections of the router are correct, if you are unsure, you can check whether all the connections of the router are correct as shown in the figure below, and then proceed to the next step.

Turn the router over and look and note down the admin login IP, username, and password on the nameplate at the bottom; The management IP is generally or; The username and password are admin by default, and the nameplate identification shall prevail.

Open the browser, enter the management IP address you just wrote down in the address bar, enter the username and password in the pop-up login window, and click OK to log in to the management interface of the router.

After entering the management interface of the router, click "Network Parameters" on the left navigation bar, first check whether the WAN port settings are correct, if you are using dial-up Internet access, you need to check whether the broadband account and password are correct, if you are using a static IP, you need to check whether the IP address, gateway and DNS information are accurate.

After the setting is completed, click on the "running status" at the navigation bar to see if there is network data traffic, if there is a change in data traffic, it means that the router is connected to the network successfully, at this time, use the computer to connect the router to try to surf the Internet, generally you can solve the problem, if there is no data traffic, there are two possibilities, one is that the broadband account in the router is set incorrectly and can not dial normally, check the router account settings again to solve, and the other is the network itself, at this time you need to contact the network operator to solve.

You need to check if the IP address and gateway, DNS settings are correct. If the ping fails, it is estimated that the IP address and the gateway are not on the same network segment. If you can ping, you need to check whether the DNS is correct, if it is a small home router, the DNS is not clear, you can also set it as the gateway address.

If it still doesn't work, you need to check whether the firewall has opened port 80, it is recommended to temporarily turn off the firewall to see if you can surf the Internet.

You can fix the network connection here:

1. Open Online Neighbors.

2. Check the network.

3. Local connection (broadband connection), right-click to repair.

It's done.

There are 2 computer connections, local connection and dial-up connection, which can be seen in the network neighbors, the former represents the normal network card, and the latter represents the normal Internet access Check these 2.
