Can't add 2nd laptop

Purchased Wireless Notebook "G" Kit. Setup base unit on
home computer #1 (Windows XP), added home computer #2
(running ME). Next, I added setup work laptop #1 (windows
2k). Home computers 1+2 in same workgroup (can share
printer/files) OK. Laptop #1 is work computer (running
VPN and domain setup) so no sharing enabled.

Trying to add MN-720 adapter to 2nd work computer (also
Windows 2K and VPN) and am constantly getting WEP not
valid error (128bit a.k.a. 26 character password)...Have
typed it about 20 times, so confident its not a fat-finger
issue :-)

Swapped MN-720 cards between laptops and both work on
laptop #1.

Interestingly, on laptop #1, when I look at setup wizard,
I see 2 line items. One line item for adapter (MAC# on
PCMCIA card) and 2nd line-item is Base unit (MAC# on base
unit). Laptop #2 only shows MAC# for adapter. Also,
running Base Station Mgmt tool shows 4 computers attached
in DHCP Client Settings (includig laptop #2 with WEP not
valid error message). Checking Network Settings on laptop
#2 shows an enabled LAN connection for MN-720 adapter.

Not sure what to do on this one? Any ideas would be
appreciated.

Thanks!
