I see this particularly after a resume

Linux chickenhawk 2.6.31-5-generic #24-Ubuntu SMP Sat Aug 1 12:48:18 UTC 2009 i686 GNU/Linux

From watching /var/log/daemon.log and dmesg I'd say something cause it to lose several beacons, wpa supplicant disassociates, and this problem happens, which prolongs or prevents reassociation. happens the same whether I'm on an autheticated ap or an open one.

Disabling network manager and connecting to an ap manually appears to preclude this though I would also observe that once this happens I generally remove the kernel module and reinsert it.

card is:

01:00.0 Network controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)

part of dmesg follows:
