About the Internet access of the router, ask all the heroes

1.If it's a switch, you can plug it in any port.

2.If it is a router, you have to plug all the incoming and outgoing wires into the LAN port.

In addition, because you are a campus network, the line that comes in should directly belong to the LAN access. Therefore, the router is directly used as a switch, which is the connection method mentioned in 2.

But there is also a reason to consider, just to mention, but there should be no such situation, that is, every computer that goes online, should be automatically obtained IP, and you should not need to set the IP or bind the MAC address on the main router.

One more addition.

3.If you plug the incoming line from the campus network into the WLAN port, and then connect the other two lines to the LAN port, you must also go into the settings in your router to see the relevant settings of the gateway of your subnet, so as not to conflict with the gateway and subnet settings of the campus network.

In fact, the second method is the most direct and effective. You don't even need to use it to set up your router.

Hello! You plug the broadband back into the WAN port of the router, and the desktop plugs into the LAN port of the router.

After logging in to the router, in the network parameters, click on MAC address cloning and then press the "Clone MAC Address" button inside.

After saving the settings. Then test whether the router can access the Internet.

It's your router problem! Restart your router! First of all, you need to do a factory reset! Then go in and set it up! Choose Always Connect! Don't choose to connect on demand! If I'm on the spot, fix it right away! Give me a point.

Check that your routing connection line is connected correctly.

Set the IP information of the desktop computer to the WAN port of the router, plug the WAN port of the router into the main line, turn on DHCP on the router, and then change the IP of the desktop computer to automatically obtain.

You have to wipe the cable connecting the main line to the computer at the AN port, and then try again. Good luck.

Have you ever changed your password? If you change the networking parameters in the router from the new settings!

It could be a router setup issue. If your router is set up with a Mac Allow Access List or other similar feature. You won't be able to get on. You manually set the IP to change the MAC to try.

The router settings page could not be opened. Explain that your computer has no way to connect to the router to see if your network card interface is good (the copper interface cable in the interface is oxidized) it is best to change the network card to see if there is a problem with the network settings in your computer.

Use the routing configuration page on your neighbor's computer to see if there is MAC address filtering or MAC address binding. Then look at whether your IP is in the range of the IP address pool in your neighbor's router, and see if the DNS is the same.

The problem is weird enough!

You can only check first, your network card, if your network card and the crystal header, not fully contacted, will also show that it is connected but can not access the Internet.

Your neighbor checks both ends of the network cable he uses to see if the 8 cables are arranged in the same way, and if they are different, redo the network cable head.

You can also try a solution that is not the way to go. When using the cable from your neighbor's house and your computer, use the network cable in a different way, which is the same cable head that your computer uses on the current router. Don't ask why, I don't know why it's solved, and I can't analyze the principle.
