OT: 802.11g via USB1 vs 802.11b via pcmcia

[Andrew Gould]

I have an old computer that has USB1 ports and no internal wifi card.  I
have a 802.11b card I can use via pcmcia card and a 802.11g adapter I can
use via USB1.  Which wifi setup should I use for better performance?  (I've
never been clear about the speed of pcmcia.)

Thanks,

Andrew
