I have a Billion Bipac 7402VGO Wireless Router and am trying to connect my Inspiron 6000 with its Pro/Wireless 2915ABG Network Connection.  When I set the Wireless security to WPA preshared key and create my key, the 2915 does not connect even though I have set the security to WPA Personal and typed in the key of 12 characters.  Has anyone had similar problems with security and the 2915 connector?  Is this possibly a software update issue for the 2915?  I have a desktop computer with a wireless card and it has no problem connecting to the Router with WPA security using the preshared key.  This leads me to conclude that the problem must be with the 2915 connector.
