Comment 9 for bug 361461

Same "wlan0: disassociating by local choice (reason=3)" here, but without wicd.

Using NetworkManager, sometimes I can stay connected for a while, sometimes I don't.
It only happens with the local university wireless (eduroam), which uses WPA&WPA2.

No problem, on other networks with WEP security.
