I have a BEFW11S4 in my basement it is a wireless b linksys router all firmware up to date and it works great except....I built a new computer for in my basement so I wired it and it will not go online! THe cable is fine I have used otehrs and the nic is fine I coudlnt connect with my laptop either.

It sees it but it cannot reslove an ip. I am really confuzed. There are no real security settings for the wired part jsut the wirelessl

Am I missing something? I have already reset it.

EDIT: and set to factory defaults
