for both your internet speed (sub g) and you adapter speed (g). No real need to pay more for a n if this is the intended use.
I have a belkin n router and a g adapter. The router is no good anymore. My question is do i need an n to play multiplayer games with lots of people? I never had a G before and my internet speeds are lower than what G offers. I get 15 mpbs max. So which one is right for me?
