Thread: Can't get wireless to work on Ubuntu 10.10

i installed 11.04 on new lenovo t420 having major problems (namely kept logging me out randomly , programs crash inexplicably) went 10.10.

when got desktop, there no option search wireless networks, strange because had no trouble in 11.04.

seems i'm missing driver or something.

here's info:

i'm running ubuntu 10.10, 2.6.35-22-generic i686 on new lenovo thinkpad t420 alongside preloaded windows 7.

iwlist scan:

code:

lo        interface doesn't support scanning. eth0      interface doesn't support scanning.

sudo /etc/init.d/networking restart:

code:

 * reconfiguring network interfaces...  ignoring unknown interface eth0=eth0.

sudo modprobe iwlagn did nothing.

tried installing compat-wireless (http://www.orbit-lab.org/kernel/comp...-03-31.tar.bz2), didn't work.

@ point don't know do...please help!
