Comment 0 for bug 414560

I cannot find any rhyme or reason to this, but my

01:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)

seems to like to disassociate/reassociate a lot since I started testing karmic as of alpha 4.

A typical dmesg excerpt:

Performance drops significantly when this starts going on. At times it becomes impossible to look up hosts, etc. Other times, it will run fine for hours on end.
