Help with issues regarding installation of Debian

NetworkManager does not detect wireless connections

Postby dokondr » 2012-08-07 21:46

I have just installed Debian 6.0.5 (Squeeze) on HP Probook 6560b.
Problem: NetworkManager does not detect wireless connections, which I easily connect with my Mac at the same place. NetworManager connects to ethernet, though.

In /etc/NetworkManager/NetworkManager.conf I have:
[ifupdown]
managed=true

Please, help.

Well, it should be false. Anyway, there are various possible causes.

Believe it or not, we cannot know what your network device is unless you post the relevant lines of lspci -vnn.
Are there any relevant messages in dmesg? For example, a request for a particular firmware.

Thanks for your help!

Here are relevant lines from lspci -vnn:

25:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)
Subsystem: Hewlett-Packard Company Device [103c:145c]

and dmesg:

[ 17.752673] brcm80211: module is from the staging directory, the quality is unknown, you have been warned.

It looks like BCM4313 802.11b/g/n Wireless LAN Controller fails to start?
