Hello

Me and my fellow room-mate discovered earlier today that when-ever i turn on my computer, the other 3 people in the room's connection becomes very unstable, and becomes stable again if i shut down my Wireless network card.

From this, we're drawing the conclusion, that the card in my computer is simply too powerfull, and creates alot of noise.

Can anyone help us fix this problem? I've tried rearranging my antenna to point away from the other computers, which helped abit but not much.

Currently, I've detached 2 of the antenas, but i dont think this as a viable solution...

It's my schools network, so I cant really find out exactly where it all goes...
But there only appears to be one router in the area, but it has 6 antennas on it...
3 on top, in the pattern 5 Ghz, 4.2, 5 and
3 on the bottom, following: 4.2 5 4.2

The yellow marked network, I believe to be the one the others connect to, blue is me.

I managed to force my computer onto the 5 ghz band, which seems to help alot, but it's still not as good as when my computer is off
