If you are having a problem where your wireless Xbox controller is not being detected by your console (the circular LED keeps blinking), despite changing batteries, this simple trick will help you out.

How to Connect Controller to Xbox

There's a small button on the top right corner of your controller above the right LB and LT buttons. You'll see the same kind of button on your console (below the memory card).

Press and hold both button simultaneously, for a couple of seconds.

Your Xbox will simultaneously search for your controller whilst your controller searches for the Xbox. This should solve your problem.
