So... How did you even boost the signal anyway?

You have a wooden house, right? In a concrete house, one wall causes it to not work.

For my 5th grade science project I studied an ice cube.

Was it... a cool project?

My Wii U gamepad can work on the floor below, and one room distance.

Like so many aspects of the Wii U- one of the best features of the game pad- off tv play is hampered by the lack of range for it- I can t even use mine from the back of the room that the console is in_ it is a play rom so it is bigger than the other rooms in my house but I def can t use it n other rooms in the house- if they had made it w similar range as a typical home wireless set up, that would have been great- along w better battery life- I m lucky to get 2 hrs of batt life

It was an ice cube. You tell me. 

I live in a typical UK house. Wii U gamepad works in all adjacent rooms, including the one directly above, but not in the one diagonally above. Nor will it work on the stairs.

Fifa sucks

In Germany, too. We learned building solid houses by the Grimms tales ;)
