thanks for the info meem! can you think of any other way
to diagnose an incorrect WLAN key that doesn't involve
non-response from a DHCP server (since we don't
want to lump DHCP server failures in with incorrect
WLAN keys)? i played around with this thinking
the opkts statistics might help, but the DHCP
requests are counted even in this case of course. thanks!
