No Wireless on Thinkpad T41 with Ubuntu 12

  • 772

I just installed Ubuntu 12 on my old Thinkpad T41. I've done this once before but back then I installed Ubuntu 11 first and upgraded to 12. This time I''ve used the Mini iso file.

Before the wireless worked perfectly without any tweaks, but now, it's checked off as enabled in the notification area, but I can't see any wireless networks.

If I do nm-tool I can see that for the device wlan0, the driver ath5k is used, but it has state: unmanaged.

    I (kind of) solved this be installing Ubuntu 10, and then upgrading my way up till latest version (12.04). Now everything seems to work just fine.

  2. Edit /etc/NetworkManager/nm-system-settings.conf and change:

    Managed=false

    to

    Managed=true

  3. Did you assign any static ip address for your wireless card earlier?

    You can check/edit /etc/network/interfaces file.
