No Detect WPA wireless LAN's

Hello

 

I'm having a problem with detection of wpa's wireless lan's, either with adhoc or infrastruture lan's.

I cannot see any of those.If i setup a adhoc connection with no encryption, i can see the connection.

This happens with C610 and C840, with the Truemobile 1150 wireless card, version 7.86.15.638 - 29-09-2003, that i download from the Dell Support site.

 

Any body have the same problem?

 

Thanks in advance...
