Hi,
I have Edimax EW-7811Un USB dongle.
The reason I purchased it was that I needed as small close-range AP to
connect my laptop to my work PC. Now, I have not managed to make it even
connect as client.
I have attached various logs and information about the HW from when I
was attempting to use it as AP. The client kept repeating
wlan0: authenticate with 00:1f:1f:e4:5b:67 (try 1)
wlan0: authenticated
wlan0: waiting for beacon from 00:1f:1f:e4:5b:67
over and over, but never really connected.
Can you give me some advice on how to debug this? Where can I create a
formal bug report, with kernel bugzilla down?
Oh, this is with 3.1.0-5.fc16.x86_64 (Fedora 16).
Thanks for your help,
Jan Dvorak
