Online WDTVLive Hub to Offline WDTV LIVE?

I’m considering upgrading my WDTV Live to the new Live HUB.

I’d like to put old WDTV Live box in the bedroom, however the bedroom is without wired internet access. Apparently with the new HUB, I can use the old Live box as a stand alone media player that has no external storage attached. Obviously It will need to be online for the HUB to see it. Is there a WiFi thing that I can attach to the Old box that will work well enough to stream off the HUB?

Thanks

I use a buffalo N USB adapter on my WDTV Live and stream the movies from the WDTV Live Hub.  I have no problem with the streaming but my signal is very good for my wireless.
