truemobile and win2k problem

I have a win2k professional pc with a pci to pc card adapter (TI
cardbus) and an Avaya gold card. It works great with an Orinoco
BG2000.

Recently a lightning damaged the bg-2000 gold card (the one inside)
and I bought a truemobile card to replace the damaged orinoco.
Everything worked out fine.

But, with the idea of being prepeared for further eventualities, I
bought a new Truemobile so that if the Avaya card on the PC or the
Dell Truemobile inside the BG-2000 ever got damaged I'd have a
replacement.

Anyway, I replaced the Avaya in the PC and Win2k recognized the card
instantly and asked me for the CD to install the Dell Client Manager
and drivers. I did and the client reported an excellent connection (34
db on both the pc card and the bg-2000 test partner). And the link
test had 0 (zero) lost packets at 11 Mbps. I had previously disabled
WEP/MAC Filters on the BG-2000 and I do not use DHCP.

But, I have no connection to the network! If I try pinging the
bg-2000 (network gateway)it times out without a reply. And the little
network PC screens on the bottom right corner (next to the clock) on
the PC report a 2 Mbps network link, not 11 Mbps as they do with the
Avaya.

Do you guys think this is a driver problem? Or could it be that the
card is damaged? What puzzles me the most is that the link test (on
the Client Manager) works perfectly at 11 Mbps. Yet the pings and
everything else doesn't.

Firmware on the Dell truemobile is 8.10 and driver version is from mid
2001.

Also, I really deslike the Dell Client Manager, is it possible to use
some other Orinoco/Lucent type of software with this cards?

Any suggestions will be very much appreciated.
