The wireless router can t connect to broadband when it s plugged in

1. Before connecting the modem to the router, you must set up the router.

<>2. After setting up the router, the line can be connected according to the figure below.

Note: After the modem and router are connected, there is no need to dial up the Internet. If you continue to dial up the Internet on your computer with a broadband connection, you will get a 678 error because the router itself is dialing and the computer is dialing repeatedly.

First of all, use money to guide wireless, that is, you must first use a wired to set the IP of the router, or, if you want to set a password for wireless, so that others can't use your network. After setting up, draw the network cable, find your router in your wireless signal, and enter the password.

You take a separate network cable to connect the computer to the router, and then access the computer through the computer to set up the router. If you can't connect, it means that there is a problem with the router.

First of all, I suggest that you do a jumper first, connect the router to the computer, use the computer or enter, if you can't enter, it is recommended to restart the router, in order to ensure that the router is not broken, the line is not a problem, if the infinite can not enter. Just restart indefinitely. Until you go in, because there are network operators that provide networks that really make routers miserable.

Or some routers are not very easy to use.

Without setting up the router, how do you get on. Unless you're using it as a switch.

Change the router and give points

View the network information, IP address, and gateway information obtained by devices that can connect to and access the Internet.

Check whether the network information obtained by the computer can not access the Internet is normal, if it is normal, you can enter cmd in operation, enter ipconfig flushdns and press enter, and then enter arp -d and then enter, if it still does not work, disable the network card, and then enable the network card to try.

1. Set the router account password to see if there is a problem.

2. If it is convenient, set the local DNS.

3. The local computer should be in the same network segment as the router.

Reset the router first.

Then go to the router and reset the broadband account and password.

Try again and see if it works.

Broadband can access the Internet normally, but the solution is that the Internet cannot be accessed after the router is properly connected and set.

ADSL enters the home, and the network cable is inserted into the WAN port of the router and cannot be accessed correctly, and the indicator light of the WAN port of the router is not lit.

If you suspect that there is a problem with the network cable entering the home, remove the router, insert the network cable directly into the network cable socket of the computer, and enter the account number and password to connect to the broadband.

Able to access the Internet normally. So I suspect that there is a problem with the router, and I use another route to connect and set it up correctly, but I still can't surf the Internet normally. At.

Enter the WAN port found parameter in the IE address bar, and the WAN port is not connected. Observe that the WAN port indicator does not light up.

Try to cut off the crystal head at the entrance end of the network cable and make a new one. Set it up properly after connecting the router. Everything is ok

Analysis and conjecture: The network cable is composed of 4 pairs of 8 twisted pairs, and there are 4 actually used cables. It is estimated that only two of them may be used for broadband access.

Or connect 3 roots to access the Internet normally. You may need to connect all 4 routers to connect them.

Try to modify DNS.,Replace it with Google.,It seems to be.,Actually, I don't think it's necessarily a DNS problem.,The key is that you couldn't get on it before.,Will it be a routing problem?,Is the login normal?

It is not recommended to use 360 antivirus, it is easy to kill by mistake.

Could it be that you checked the wrong port when you accessed the router broadband?

See if the router's DNS has been changed.

The local connection of the computer automatically obtains the IP and DNS to try.

It is recommended to turn off 360 antivirus first!!

Don't use the preferred DNS server, it will have a certain impact on the speed of domain name resolution, use your local DNS.
