Topic: Supported wi-fi dongles?

I pulled my chumby out of storage after moving cross-country and the network appears to have died. I'm probably 2 years or more out of warranty so I pulled it apart to check. It looks like the wi-fi dongle died - it doesn't show up if I move it to the back of the chumby or indeed to a different computer.

So, what can I get as a replacement that (hopefully) won't require re-flashing the kernel with new USB IDs?
