Wireless issues on Thinkpad T60 with ubuntu 7.10 server edition

[Jet Ley]

Hi,

I have installed 7.10 server edition on thinkpad t60. My lan ethernet
connection is working but wireless does not work.  From the kernel log
messages, "Dec 15 11:23:46 jetley-t60 kernel: [   13.610000] ipw3945:
Detected Intel PRO/Wireless 3945ABG Network Connection", I can see that
ipw3945 finds Intel card but iwconfig cannot find a wireless interface. Do I
need to do any other configuration for wireless to work.

Thanks,
Jet
