I've tried power cycling everything in every way possible. That doesn't seem to be the issue. I know all the cables work because I can take it out of the Linksys and plug it in to my laptop and viola it works. Perhaps the DHCP lease is locked to a MAC address for a period of time. It could be that the Linksys died but it literally was working just fine with Comcast just hours prior to me testing it at the new location. I think I'll try feeding it a dhcp address from a dhcp server running on a Linux machine and see if that works. I'll also play with the STP settings. Thanks for the ideas. Eric
