Comment 19 for bug 524454

had the same thing.

After I had drained my laptop battery to the max the laptod hibernated for the first time in Lucid
after putting it to the adapter i rebooted
then network manager was disbled. This hs not been the case before i hibernated
the /var/lib/NetworkManager/ file had the mentioned falses, i deleted it, i rebooted.
The wireless network was not disabled but did not see any networks
The wired network was working perfectly
tried a few things and rebooted a few time
finaly i put a noresume in grub, rebooted and the wireless got working again.
