I have been working on the same problem. I found information on the router settings on the USR website http://www.usr.com/support/8054/8054-ug/three.html but after the wizzard was run and PPoE setting was set to automatic (IP is Dynamic), it still doesn't work. I believe the modem needs to be set to bridge mode, instructions for this are on AT&T's website. http://helpme.att.net/article.php?item=12197 Good Luck.
