This computer, (running Ubuntu 11.10 oneiric) I'm writing from is connected to the inet via Clearwire modem, to Belkin N600 DB wireless router (ethernet cable). This router successfully connects via wireless to a laptop in this house.
My problem is my computer (Dell Dimension 4500) in an adjacent room is successfully connected (by eth cable) to a Netgear N300 Wireless Router WNR2000 v2, but I can't connect it, via wireless, to my Belkin router. That computer does get inet access if I physically swap it to the same setup I have in this room.
