Hi, I have a Gateway desktop DX4860 (also have SNID), not sure but think it may have 802.11g (Gateway wouldn't help). I'd like to upgrade to a N900 router hoping that'll stop choppy streaming troubles. Can you tell me if this model has "g" or "n" band capability, and if only "g," how can I upgrade the desktop to allow for use of both the 2.4 Ghz frequency AND the 5 Ghz frequency of a N900 router?
