I suffer this same bug. Also KK 9.10 Release Candidate
2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux
When connection hangs, sudo rmmod and sudo modprobe ath9k, they both fail. The only way to get another 10-20 minutes of connection with
03:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)
on my Acer Aspire 5738ZG is rebooting the system.
