network-manager can't find my wireless devices

asimov · 06-30-2006, 02:19 AM

i'm using ubuntu dapper on Thinkpad R50e laptop (with IPW2200). network-manager is not letting me switch to wireless networks. it only shows the wired (LAN) option.

Now I can't connect to wireless networks using this applet. how can I fix it?

Open a terminal, post output of:

Code:

/sbin/ifconfig -a
/sbin/iwconfig -a
/sbin/route -n
/sbin/lsmod

Note, you can redirect output to a file:

Code:

/sbin/lsmod > lsmod.txt

I have followed the link instruction, commenting out wireless card setting in the /etc/network/interfaces; however, I still can not see the wireless card ipw2200 appeared in the networkmanager.

kernel 2.6.20/ debian 3.1 testing

The problem does not happenes if I switch back to use the kernel 2.6.16. It is a bit weired. How to solve this? or where to check the log to find out any clue?

Thank you very much.
