Orinoco gold just supports 128 bit WEP as standard, the silvers are 64 bit.
You are right,well for the most part. The lucent cards with the white connector support TKIP also,which is a fix for WEP. It is basically a patched WEP as i understand it which fixes some problems. Still not as good as WPA/WPA2. Apparently the netgear MA401 is the only easy to find card ideal for WPA/WPA2 once the firmware is fixed.

I was wrong, Go with the netgear ma401. As for something to flash the pcmcia cards,your best bet may be to get a pci to pcmcia card adapter if you have the pcmcia slot free.
