umm, all wireless networks run on 2.4GHz
something is wrong with your controlers then. They are using a technology where they use subbands of 2.4GHz so they don't iterfere, because wireless internet, most wireless phones, microwaves etc all use 2.4 GHz.
But I've got one and it works flawlessly. I would reccomend getting a usb extender if you arn't really close to the router, mine is a floor up so I taped the wireless thing to the wall near the ceiling and used a USB extender cord to connect them...
And I know my spelling sucks balls.
