Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Confirmed


Description:
Under Breezy, the wifi works out of the box. With Dapper, the wifi
network is scanned but the pcmcia card can't connect to it because the
signal power is at 0.

I have a PCMCIA wifi card on my laptop with atmel chipset.
Under Breezy, it works out of the box. I just had to plug and play.
I dist-upgraded to dapper (kernel 2.6.15-18).
Since then, my card is still recognized, it can scan the wifi network available, but it can't connect to it. The Signal power is to zero.
I made a test :
- using Breezy live CD : works good
- using Dapper live CD Flight 5 : can't connect (signal power 0)

So here they are infos under breezy :
