Wi-fi won't connect in 11.10.

[la_serpe]

When I updated my system to 11.10. wi-fi stopped working. I can see the available wireless networks but when I try to connect I always get the message that the password is incorrect. Password is good for sure because I actually updated the system while connected through wi-fi. On my second computer it also works fine. I even tried 3 different kernels with no result. I suspect the problem is in the ethernet driver. Here's some info:

uname -a:

Aspire-3100 3.1.0-030100rc10-generic

lspci:

06:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
06:02.0 Ethernet controller: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01)

Anybody knows how can I get it working?

It's unusual to not be seeing any scan results here.

Could you please try the following two commands?

nmcli dev wifi list

iw dev wlan0 scan dump

For the second one, you'll need to install the 'iw' package (sudo apt-get install iw). The goal is to try and see elsewhere if there are scan results from the driver. If nothing shows up in either command, this would end up being a driver issue.

Thanks in advance!

"nmcli dev wifi list" shows:
SSID BSSID MODE FREQ
RATE SIGNAL SECURITY ACTIVE

"and iw dev wlan0 scan dump" shows nothing

The strange thing is that I see the wireless networks but I can't connect.

My wi-fi is working again. I found this command at some forum:

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source

After that I run:

dpkg --configure -a

and afrerwords aptitude and suddenly wi-fi was working. I have no idea how did I do it but it works...
