Comment 27 for bug 336055

For the original bug where NM tries to connect to an access point that's clearly not present, that's actually a kernel bug which I traced down this week. The drivers weren't correctly aging scan results from before suspend, thus when NM woke up all the APs from before suspend looked like they had been seen less than 10 seconds ago. These patches were submitted to the kernel this past week and should get into Fedora fairly soon; though we may need to backport them to recent kernels.

These patches should cover most cards in use today.
