Hi all,
I'm here again reporting another possible problem with my wireless
card and b43 driver. Please don't bite me this time, I promise I'm
sending all useful inputs :D
Well, the problem is:
- After boot my laptop, the wireless card is not connected to my wifi
network. But if I just type sudo iwlist scan, then it connects.
- The same problem does not occur if I use ndiswrapper or another
laptops.
I believe it's a feature of mac80211. It only scans for APs under some
circumstances. Setting ESSID triggers scanning. I suggest that you do
it in this order:
bring the interface up
set the WEP key
set the ESSID
Hi,
I tried this, but it didn't work also.
By the way, your AP is set for shared key authentication. It delays
authentication because mac80211 tries open system first and fails.
I can wait for 5 minutes and it still doesn't authenticate.
The weird point is it does not occur with ndiswrapper or with other
linux laptop.
Even without that step, shared key authentication needs 4 packets to be
sent, rather than 2 for open system authentication. It's believed that
shared key is even less secure than open system. See e.g.
http://www.networkworld.com/research/2002/0909wepprimer.html
It's just a home network :) . But thanks anyway, it's useful to know.

David Cohen
Can you try this patch?
Same problem... didn't fix it yet. Same output logs also.
