wifi help need w/ WEP encryption

Any help appreciated. I can not get WEP encryption to work under Linux
(Mandriva LE2005) with my PCI wifi modem (ZyXEL ZyAIR G-300, which states
on the box "Great security with 64/128 bits WEP and Wi-Fi WPA). Of course
I would prefer WPA, but I will take WEP 64 bit at this point in time. WEP
64-bit works great with WindowsXP, so I know the router and modem are
capable of doing this. Without encryption, the wifi modem works great
under linux.

I have triple-checked the 10 digit (64bit) hex code of the router. Here
below is the output of ifconfig, iwconfig, lspci, /var/log/messages. What
more can I do? Perhaps WEP is just not possible under Linux with this
modem?

I am using a linuxant.com driver; I am open to trying some other
driver (tried Mandriva ndiswrapper before linuxant and could not get that
to work, but I believe I once heard of a more specific ndiswrapper site
with better drivers, not sure where that is?)
