droppy Wireless connection

[Night-Stalker]

I recently bought a Belkin G wireless desktop card for a friend and it works great at my house. When i took it to his house, his connection keeps dropping every now and then when he is gaming online. I tried nearly everything, I even got it exchanged for a brand new one and its still happening. Any idea on how to solve this?
