Status in “network-manager” package in Ubuntu: Incomplete Bug description: Whenever I leave my computer long enough for it to suspend for a few hours and then return, the computer is unable to connect to any wireless networks. It keeps prompting me to enter the already known security key, but it never connects. It is fixable by restarting the machine, but nothing else seems to work.
