MSI do USB / PCMCIA / PCI versions of a wireless card, that can be swithed into AP mode too, so you could have one set as AP and one as client ??

but now a second question

WHY ??? :confused:

I think if you re-read it, poster just wants two PC's to connect wirelessly
IP config / domain not withstanding

Yes they can talk
just bear in mind HT's bit
they have to be compatable
