Wireless Router dropping when playing Xbox.

Ok this is going to sound strange but...... Even if I unplug my xbox from my router (I don't have a wireless adapter) and play a game offline, it still disconnects my Internet. This only happens when my xbox is on so it is definitely that causing the drop
in Internet. I can only assume that it is the wireless controller connection that is causing this? Had anyone heard of this before? I have tried changing the channel my wireless router works on but this has not solved the problem.

I am completely stumped, any suggestions?

Are you able to take the Xbox to another room and try it? If not it could also be that there is interference between the Xbox and Routers wireless signal that will cause the drop of signal and disconnects.

ok after reading the event log on the router the xbox live connection was dropped (disassociated code 4) to renew the network wireless lease and it wasn't the xbox's fault. Fixed this by changing the lease time on the router.

So the moderate connection through windows ICS is still working ok plus I think I've narrowed it down to a few possibilities as to why the bridged open connection keeps dropping. At the minute I'm looking at snmp.exe on the computer, which was active at
the time when there was no need for it to be. Also enabled port clamping on the router.

Yes, they are both R7000 Routers. So when I set the one up in AP mode, it just pulls the settings from the main router. I even disabled the Wireless signals I am not using.

I am only using the 5 GHZ on the Router, for the Xbox

2.4 GHz on the AP, both Normal and Guest.

All Other Wireless is disabled to ensure no interference.

What is getting me concerned is that the Desktop dropped off the UPnP list at the same time the Xbox did, and returned the same time. I never noticed a disconnect on the desktop, but I was not on it when I got disconnected on the Xbox. The desktop is hardwired
direct to the main router.

Try going to your routers settings online, when your in look for 'wireless settings' in there you should see a drop down menu saying 'auto' click that and change it to '1' or any other number.
