As far as I know, at least one of them should be able to do at least WPA.
The cards are:
1. Netgear WG511v2 (the made in China one) PCMCIA.
2. Linksys Dual-Band WMP55AG PCI.
The Linksys' drivers were last updated in 2004, so that I suspect rules out WPA or WPA2. I checked a few places for firmware, however each time I downloaded the 'firmware' it turned out to be the 'drivers' again.
The Netgear isn't any different, drivers stopped coming a long time ago, which is a shame.
Pity me and my poor buying decisions
