I'm living in a house with 2 other guys that regularily use the internet.

In the house the router is positioned on the bottom floor livingroom as it has to be close to the tv set for the virgin media channels.

The house has 3 stories and my friend is in the one on the second floor directly inbetween me and the router.

I have to use a wireless usb for my computer to get coverage which usually works well until my friend in the room below starts using the internet, then it just cuts out.

I need to find a solution to this problem before i can play poker with any sort of seriousness as its costing me quite a few buy-ins when I jus cut out in the middle of a game.

Any suggestions?
