I see the Wii has built in wireless. It's not 802.11n but it should still work, just not as fast. You may not even notice it.
The router location should be ok. Try to place it about 6 feet up. Like a small shelf or something up on the wall. I doubt you'll need the AP at this point. Don't spend the money if you don't need to.
Good Luck! I'll be away for a few hours, back later tonight.
