Got a small home networking problem. I have a DSL line from at&t a modem from them 2Wire 1701GH which servs as a wireless router. I am trying to connect a Linksys WRTU54G-TM router to it because that one has a jack for a phone line so I can have my VOIP phone. I have connected a cable from port 1 of 2Wire into WAN in linksys. I have disabled DHCP on the linskys router but every time i access the web I get a message from 2Wire that a router behind a router was found and this issue needs to be resolve by applying a ip address for the given computer. When I press resolve to apply the changes I cant no longer get a connection to the internet. Although my phone line works perfectly fine. Can anyone give me any ideas of what can be wrong or how i can set iot up in order for it to work correctly?
