I have tried everything possible, but my new AT&T Motorola 2210 modem works fine with just the DSL line, but not when I try to hook up either my LInksys router or Netgear router. The wireless network shows configured, but the internet connection is not detected. I've have tried tech support for each and no one can figure it out! Should I just return the AT&T modem and try the new 2wire modem/wireless router instead??? THOROUGHLY FRUSTRATED.
