troubleshooting wireless configuration problems (association / authentication part), OpenSUSE 12.1

Hi,
can anyone help me with troubleshooting wireless configuration (association / authentication part)?
I reach the point where the scan reveals the required AP, but no network connection is available.
Configuration was via “YaST / Network Settings” because I want the connection to be available for all users and the laptop hardly leaves home.
Firmware and driver seem to work fine and the scan reveals the AP.
pinging the AP (wifi router) results in “Host Unreachable”.

Is there any description which logs to check to pinpoint the problem?

‘/sbin/lspci’
03:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 01)

‘/sbin/lspci -n’
03:00.0 0280: 14e4:4315 (rev 01)

‘dmesg | less’

‘/usr/sbin/iwlist scan’
also reveals the required AP among others.

I do not understand from your post if you successfully authenticated to the wifi router or not…

You say you saw the AP so the scan and hence the wifi card work but you say network connection is unavailable so I guess it’s a misconfiguration from your side.

Have a look here for a step by step instructions with relevant informations. You can start at 20.5 but I’d suggest to read it throughly.

Did you already disable NetworkManager from Yast?

What ifconfig -a shows?

What’s the content of /etc/resolv.conf (did the router send you the dhcp ip / gw and dns) ?

Cheers.
