My PC has a Dell wireless 1505 mini-card. It also came with a Netgear WNDR3300 wireless router. Initially, the router was set to use WEP. This worked well. When I change the router security to WPA I lose the Internet. When I set it back to WEP all is OK again. Netgear leans toward asking Dell if the 1505 supports WPA (I see other Dell posts saying "yes"). By this I take it that Netgear doesn't think it's their problem. The router has the latest software and the 1505 card has the latest driver.

Any ideas?

Thanks!
