Hi all,
I just upgraded from 10.3 to 11.1. Wireless used to work (with a few up and downs in connection). Now it does not work anymore. More in detail: it worked a couple of times, but now it’s silent.
KnetworkManager does not even try to connect.
First the details.
Kernel
Linux rodolfo 2.6.27.7-9-default #1 SMP 2008-12-04 18:10:04 +0100 x86_64 x86_64x86_64 GNU/Linux
My wireless card is
Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection
This is the dmesg output when it relates to my card:

Here we start with the problems. Sometimes the card is able to scan for all networks, included mine; sometimes it just shows some of the networks. In the second case, there is no things I can do to make it find all networks, except rebooting.
In any case, this is the output of iwlist scan, in a case in which all networks are shown:

My network is ‘Lonesome Wireless’.
Finally, this is what happens when I listen for what my WLAN does with iwevent - nothing ever happens. I mean, I try to connect with Knetworkmanager and nothing shows up in iwevent. All I get is
iwevent
Waiting for Wireless Events from interfaces...
19:06:20.379019 wlan0 Scan request completed
So, summing up:
- wireless sometimes sees all networks, including mine, sometimes it does not;
- it usually does not connect - though it happened once that it connected;
- knetworkmanager does not seem to interact at all with the wifi card;
- I have tried to follow the thread in which it is advised to install compat-wireless, but I had not the guts to go on and make it load the ‘new’ drivers *.
Any help would be much appreciated.*
