Wireless network broken, access to WRT54G & Motorola 2210-02 via http.. denied

I have att yahoo dsl which I installed about a year ago. The process required bridging the ADSL Modem (in my case a speedstream 4100) and accepting dynamic IP addresses and configuring PPPoE on the WAN side of my Linksys router. The ATT support person walked me through the entire process over the phone even though I was comfortable with making the Linksys configuration changes as I had to do the same in China without technical support. The modem configuration was no more difficult than the router configuration as it was performed from a web browser too. The biggest warning was that to reverse the modem change (if desired) required use of a reset button because the web interface was disabled as a result of the configuration change. My advice to you especially if you are willing to attach the Linksys router to the telco modem is to contact the ATT highspeed DSL support line and see if they will walk you through it like they walked me through it. Reviewing your Linksys User's Guide and understanding the configuration of that device would probably be appreciated by the ATT Support person as well as assuring you can access the Linksys router to configure it during the call.

Motorola 2210-02 uses a ip address of 192.168.1.64. So I set the router ip address to 192.168.2.1 and fixed the problem of no communication between modem and router..
