I have a Dell Inspiron E1505 that has an Intel PROset Wireless card. I recently bought a D-Link 150N DIR-600 wireless router and am having a heck of time getting connected. The PROset card sees the D-Link router and makes an attempt to connect, but gets hung up on the security. I've never had any issues getting wifi connection before. D-Link support wasn't much help as their techs are only trained on Microsoft wireless. I've gone to Intel's website and have updated drivers, but still no go. Any suggestions?
