If you intend to add WLAN to a non-PC platform, the easiest route to
take is to use a CompactFlash or PCMCIA (not CardBus) card. Problem is,
it's kind of difficult to add either of these to a ready-built PC (yes,
I know it's possible, but there are software and hardware layers that
you just don't want to be bothered traversing - they make it MORE
effort, not less, to add WLAN support).

The gumstix board was specifically designed with Linux in mind. Again,
it's considerably "more computer than you need" for an eCos application.
Not that you can't run eCos on it, of course, but your life would be
made a lot easier if you just ran Linux on the PCM-5860 and then Linux
on the gumstix board and ported your app over. On the Advantech board,
you could use an off-the-shelf WLAN module on the USB interface.

I repeat the question: What is it that made you choose eCos? If eCos was
chosen by your professor, what is it that made you choose the PCM-5860?
