** Tags added: apport-collected
** Description changed:
Since upgrading my kernel to 2.6.38-10 (using update manager), I have
been unable to enable wireless. The wireless icon is just an empty
outline, iwconfig reports that none of my network adapters has wireless
capability (wlan0 is missing), and the wireless indicator light won't
turn on.
Please let me know if there are any log/config files I should post.
