I've been working on getting a wireless router to work with a DSL modem from AT&T.
They are using a Motorola MSTATEA modem (with built in DHCP) from AT&T
The router is a Netgear WGB511 Wireless Router.
With only the laptop connected directly to the modem, the internet connection works. The modem normally has an internal DHCP server and automatically connects with the DSL login/password. It also has an internal webpage management to configure the modem and turn these features on and off.
When the Netgear router is connected into it, it will not get a DSL based connection. I've otherwise tested the username/password and confirmed we were using the correct ones. I can login to the router's configuration webpages.
If anybody has worked with this combination of router/modem before, I'd appreciate the help!
