Windows crashes continously with 100gx

I bought a full package consisting of one 500gx router and two 100gx pcmcia cards.
Unfortunatily both cards (or better the drivers for the cards) are causing big problems.
Both of my laptops are crashing regularly since I've installed the cards with a blue screen showing "unexpected blah blah... then the machine reboots).
Upgrading the drivers to 3.70.12 did not help much.
I've heared that regulating the output power of the cards down might help... but the only option I've found for doing that was on the 500gx.... there does not seem to be a way to do it on the 100gx.

What can I do.... right now the cards are simply unusable for me.... working is not possible as the timeframe between the resets varies between 5 minutes and 2 hours... and that really stinks. Will there be any new drivers soon?... especially as I seem to not be the only one having this problem!?
