360 connection trouble

[runing.man]

Hi I don't know if any one can help with this problem but it would be great if you can, the thing is every time I turn my 360 on it cuts all my Internet connection off on everything it does this every single time for the last 2 days, up until then it's been fine, and on the modem the broad band and wireless lights will flash red then after about a minute they will turn blue then I can connect ok. But then it will go off on the first game of black ops I join for some reason. When my 360 is off my connection is fine with everything else.

Does any one have any ideas how I can fix this ?

Many thanks.

Hi thanks for your reply, the pc is working ok in every port and every other device works ok, just the xbox cuts my connection off every time wired or wireless, it was fine up till a few days ago do you think it could be the xbox it's self ?

Thanks for your help
