It's almost never that simple :)

The Syslog.txt in that first Launchpad bug shows a lot of:

Jul 18 17:17:28 molly kernel: [25847.724098] wlan0: no probe response from AP 00:13:d3:81:ac:d6 - disassociating

It looks from that bug report that NM is working correctly, but often
the driver simply disconnects you because the AP is not responding to
probe requests, or the driver has a bug which causes it to miss the
probe responses.
