>Description:
	
	Attach an ath card to a Linksys WRT54G base-station with
	a non-broadcast SSID, and a 128 bit WEP key. go into ACPI
	sleep mode, then on re-awake, although you can DHCP an
	address, your arp cache never has complete entries, and you
	have no functional 'route to host' for the entire local net.
>How-To-Repeat:

	as above. I reset my base to non_WEP, and this problem went
	away, the network comes back fine.

	
>Fix:
	NFI. I wonder if the ACPI restore-state matrix is excluding
	something from the state recovery, or if in userspace its
	neccessary to clear and re-bind the WEP state. If WEP has
	session-keys, possibly it has to be a clean re-bind to avoid
	re-use of a stale key (this is hypothesis, I really have NFI)
