At home I am connected to network 'A' and can see WLANs 'B' and 'C' from my neighbours.
I suspend my computer and when I get to work the next day, the system still thinks it's connected to the same network 'A' and that it still can see the 'B' and 'C' networks, even though they aren't there.
It will stay there forever trying to connect to the 'A' network, until it's stopped and I select the correct network.
It is not a major problem (I can just open the list of networks and connect to the correct one), but is quite annoying.
It is like (but is different) this bug: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/893316 (in the bug, the system connects to a different WLAN even though the previous one is still available; with my case it's the opposite).
I think it's a NetworkManager problem, because I never saw it when I used wicd. What can it be?
I'm using x86-64 Arch Linux, NM 0.9.6.4, Intel Wireless 1030 card (iwlagn module).
