Comment 20 for bug 548992

Right after I commented above, I started Googling in a different direction and found this bug report in Red Hat (see comment #10):
https://bugzilla.redhat.com/show_bug.cgi?id=503983

Basically they said that the N-mode that was causing connection drops, so I added this line to /etc/modprobe.d/options.conf, and it works great then.
options iwlagn 11n_disable=1 11n_disable50=1

I've tested several times with that line enabled and disabled, with reboots in between, and confirm that it does fix the problem (I can reproduce the problem again any time by disabling that line). The network connections without that fix was reported as jumping between 0 and 130 Mb/s, whereas with that line enabled, the connection speed goes between 48-54 Mb/s.

I've only tested during the last hour with WPA2-Enterprise. If I won't report further then it works with my WPA1-personal network too.
