I have AT&T Uverse. They give me a Wirless router that runs all of the phones, T.Vs, and internet in the house. I have an Airport Express that I want to connect through an ethernet port to the AT&T router. Its a 2Wire 3800. I've read up a lot on how you need to set up the DHCP and Static IPs and stuff, but I just cant get it to work. Can anyone help me?
