Internet issues

I've recently been having major issuses with my xbox 360. When ever i switch it on my internet signal stops working, and I can no longer use brroadband with my wireless laptop and my 360.....

...Now you'd think the sensible solution would to be to unplug the ethernet cable from the router right?......Wrong!!!

Forsome bizarre reason i cannot use the internet and my 360 at the same time in my house....this is really bugging me and i may have to resort to burying my 360 in the back garden. Does anyone have any sensible sudgestions before I resort to drastic mesures.

I apologise for any bad spelling and grammer, it is quite late.....and i'm quite pissed

So let me get this straight...even if your 360 is not connected to the router, whenever you turn it on, you lose internet?

Are the 360 and the router connected to the same power source?
