Err, that's interesting and all, but nobody sets up their routers with MAC address filtering, and nobody needs to fiddle with the wireless settings on a stock Windows install (and certainly not on the Aspire One: I know because I have one).
So, really, it should Just Work (assuming it's switched on), and if it doesn't it's borked.

Yes, some people do set up the MAC address filtering in their routers. Ask me how I know.
