The wireless controller allows users to play games on their Microsoft Xbox 360 consoles from across the room without the need for wires. Up to four controllers can be used at one time on each console. The controller should have a strong signal, but if you are having problems with your connection you can try some troubleshooting steps that should boost the range of the wireless controller.
Check the batteries. Open up the battery compartment on the back of the controller and reinsert two new AA batteries, making sure to put the positive and negative sides pointing in the correct direction.
Keep the controller away from metallic objects such as refrigerators, filing cabinets and mirrors. These objects can interfere with the signal.
Make sure no objects are blocking the path between the controller and the Xbox 360 console. They can also affect the signal and range of the controller.
Turn off cordless phones, cell phones and wireless video transmitters. Devices such as these can cause problems with the operation of the controller.
Synchronise the console and the controller again. Press the sync button on the controller (near the charging kit slot) and the corresponding button on the Xbox 360 console (below the memory card slots). The ring of light around the guide button of the controller should spin and then the top-left quadrant will stay lit to signify this is controller one.
