Arduino and USB wifi adapter

Hello!

Has anyone had any success using a usb wifi adapter with the arduino?

Thanks!

The Arduino is a usb "device", and can only talk to a usb "host" like a PC. The same is true for the wi-fi adapter; they won't talk to each other (at least, not without enough additional logic to remove the price advantage of the USB wifi adapter over a specialized embedded wifi adapter.)

Also, my understanding is that the low cost wifi adapters require A LOT of host-side processing to make them work; the support code just to be able to authenticate to a network probably wouldn't fit in an Arduino...

That's what I thought. Never hurts to ask though.

Just to kickstart this discussion again, I'm wondering why I can't (in theory) pry the USB antenna off of the USB dongle and make it work? I guess the WiFi shields being sold have a lot of logic coded onto memory on them, or something?

Yes that is it, they contain processors that do the USB protocol stuff leaving the small arduino just the job of feeding data to it.
