I just bought a E1505 with an internal draft n wireless card.  I have a Belkin pre-n router, and I can't get the laptop to connect to it.  It sees the network but never connects.  The wireless is completely open - no encryption, security, firewall, or mac filtering.  I even reset to factory default.  It has the most recent firmware.  I have another computer in the house that connects fine.  I downloaded the most recent Dell driver for the adapter from the support page.  Does anyone know what else I can do to make this work?
