I've been installing our stripped down NetBSD 4.0 based software on 15 
identical Dell Latitude 100L laptops with cardbus ral(4) cards. The 
customer is using 64-bit WEP. We are using the very latest netbsd-4 
sources. On 13 of the 15, everything works fine; ral0 associates in about 
5 seconds and dhclient runs fine. On the other 2, the network status 
eventually shows as active (after say 20 seconds), but dhclient doesn't 
get an address (and a manually configured address doesn't work). The BSSID 
and channel are found and correct. It's not a network card issue, I've 
tried swapping.

Any clues how to proceed?
