Anyone know how to connect 2 computer with a Rouch Router?  

you should be able to use any router of any brand as long as the Internet provider uses a standard protocol such as PPOE static IP or dynamic IP. Just connect the router and configure it properly. Go to the IP of the router (192.168.x.1) and enter in your username and password, then configure the connection by choosing the correct protocol, any related information (such as hostnames or DNS servers) and save and reboot it.

There is no need to buy their router. Is she sure the router she has works okay, has she tried all of the ports?

I have never heard of a rouch router and can't find a router by that brand on the internet so I'm afraid I cannont be a whole lot of help.

I'm guessing Hardwired so the basic things to check are:
Make sure your using CAT5e cable (basic LAN cable)

Make sure your plugged into the right ports in the router (modem is connected to internet port and the computers are connected to the numbered ports)

Can the computer see the router under the networking center?

You will also need to check the second computers networking settings to make sure that it obtains the IP address automatically and that it obtains all the information automatically. (these will be under internet explorer under the tools and then internet options)

Hi icyorchid, No two PC should have the same IP number, did you just assign this or it was given it yo you by ATT? If one PC is say 192.168.1.1, the other one should be 192.168.1.2. If you change IP address it is a must to restart every unit even your router.

I don't know how to help you myself. I tried to look the information up online for you but alot of people just say it is a pain to do and that it is awful and they would never try to do it again. It must be very hectic to do. I'm sorry I could not help you either.
