Mini-pci 802.11 compatibility

[tp23]

I understand that if a ThinkPad bios doesnt support a particular piece of hardware, drivers will not install. My question concerns mini-pci wireless lan cards and I'm curious which brands of cards are actually bios compatible with T-2x series machines. If the drivers install and the OS recognizes the wireless lan card and reports it's working ok and yet the card cannot connect with a working wireless router, there obviously has to be something wrong with the setup.
This is a brief explanation of my issue with two used Broadcom BCM94306 802.11 54G b/g mini-pci cards and two T-2x series ThinkPads, two identical cards will install but not connect with a working wireless G router. Network properties are set for auto detection of addresses, and radio function is on.
The antenna in use in a T-20 is factory installed in a used replacement display and the other antenna I installed in a T-23 is situated in the leading edge of the palm rest, and my workdesk is less than two feet away from my router. The antenna in the T-23 is one of two new coaxial antennas I bought with the cards, and the other antenna I taped to the top of the display housing after the internal antenna seemed not be working.
Also, the T-20 mini-pci port worked with the IBM 10-100 nic installed. Yet neither machines after the wireless upgrade connect with my router. I temporarily use a D-Link Air-Plus card and a Belkin USB wireless adapter in these two machines and I only want to use the mini-pci wireless cards in them.
I have a chance to buy a couple new PRISM 802.11 b/g cards but are fearful that these will not work on these two systems.
Any help will be greatly appreciated.

Upgraded my router's firmware to the latest version.........still does not connect with these mini-pci cards.

Hmm, no. I hade the same problem when I tried to install a non-IBM mini--pic in my t30. Apparently everything was ok, just no signal was ever detected. I think there is a lot of information on the matter if you search the forum.

I tried that but didnt find anything conclusive....besides, the dealer I bought them from claimed they were compatible with T2x series......
