Yes, just remember your wifi conection should use WEP (there is no WAP support).
Yeah my Sharp Zaurus doesnt need further configuratoin when using just plain WEP so I've stuck to that standard.
Just wondering if the PCMCIA wifi card doesnt work if theres any reported issues with using PCMICA <-> CF Adapters.. wondering if chipset on adapter plays any role in incompability etc.
Probably have to find out myself

Does the PCMCIA card definitely have to be 16-bit interface or can it be 32-bit?
