Every time I connect my Bluetooth headphones (Behringer HC 2000BNC) to my Android tablet (Archos 70 Oxygen) the router stops working correctly. In the mild cases wifi devices can no longer connect while the router continues to send beacons. In some cases even ethernet devices can no longer access the internet. I have to power cycle the router to bring it back to life.

To be clear, I'm not talking about a temporary problem. The router remains permanently unusable even if I power off the tablet and headphones.
