I'm looking to get a wifi adapter for a mag254 I ordered. I am going to need one with a good range because I plan on moving to a bigger location and may possibly have two floors. Need something that if my router was on the first floor (and assuming the router has a good wifi signal range), then my mag254 wifi adapter on the 2nd floor would be able to pick up the connection and stream fine. I know this is possible as my dad in law has a router locked inside a cabinet in the basement and I still got good signal on the main floor.
