It probably won't be there right out of the box unless the stick uses the same chipset as the N800 (which it better shouldn't, or it would have the same problem), but theoretically, you can add all missing modules.

However, the N800 uses a ARM CPU, and as many WiFi chipsets have closed-source binary components or assembly code as part of their Linux drivers, it is rather unlikely that you could compile a driver for your WiFi stick - beyond outdated b-only hardware the chances are somewhat slim.
