When I first got wii my neighbors wifi connection i share, would disconnect every 3rd race in mariokart, the only online game I used at the time. Since getting a new router its never happened again. The router is downstairs, and one room away from my wii u, and was the same for wii. I entered the wep key and that's it...nothing else. Idk if that helps but it disproves the theory the wii had better range. Oh btw my connection is always 4 full bars or whatever when I look at my available connections.
