If the wifi on my iPod Touch is on nothing else on the router will connect to the internet

Ever since I updated my iPod Touch 4th Gen to iOS 6, If the wifi on my iPod Touch is on nothing else on the router will connect to the internet..

It's the weirdest thing.

My Wired and WiFi computers are experiencing DNS errors, unresolved URLs and in general having difficulty connecting to the internet...

That is.... UNTIL I SHUT OFF THE WIFI ON MYiPOD 4th Gen TOUCH!!!

Then everything works fine.

I've reset my router, several times.

I've reset my Cable Moden, several times.

The problem persists until I disable the WiFi on my iPod
