Step 1:

First make sure that your modem is working. Connect your main computer directly to the modem. Make sure that your main computer is able to access Internet directly through the modem. If you are not able to access internet directly through the modem then contact your service provider and get your modem working first.

In case of DSL connection, you may not be able to access the Internet directly through the modem. In this case you must have PPPoE User name and password from the DSL company. Make sure that you have the correct PPPoE user name and password. if you do not have PPPoE user name and password then get in touch with your Internet service provider and get it.

Step 2:

Connect the computer and modem to the Linksys WRT1200AC router with the Ethernet cable. Connect the modem to the Internet port (which is standing alone ) and computer to the Ethernet port. If you connect the modem and computer to the wrong port, you will not be able to open the Linksys router setup page. If you have computer connected to the WAN port then it will not communicate with WRT1200AC. Connection is very important. You will see 4 lights, Power, WAN, wireless and Ethernet.

One comment on “Linksys WRT1200AC router setup

  1. linksys wrt1200ac router not working.
    Connectivity problem with WRT1200AC.
    I have a problem with my WRT1200AC router. Two problems actually.
    First one is that when I am connected to the 5Ghz channel the connection is getting lost quite often, I had a massage about that before and after few advices it is still like that. I have changed the channels so they don’t overlap with my neighbour wifi and few other things that were recommended from you guys.
    The second one is more recent . After not resolving that drop of the connection on the 5Ghz, I ran a cable to my primary computer for better signal. It worked very well in the beginning but not anymore. Now when using the cable the connection to Internet is dropping again often. Then I connect the computer on the wireless and there is Internet. After some time the cable is on again.
