Here are the instructions for changing the channel and also displaying what the channel the Vudu Wireless kit is using:

Display channel setting:

- On Home 1 (router connected) press the reset button and release it before 5 seconds. The power LED will blink out (at 1 second intervals) the channel that the Wireless kit is set to. This should be between 1 and 11, both inclusive.

Manual selecting channels:

By design, the Wireless kit will choose a channel which has minimum interference. Automatic channel selection is the default mode. On the Home 1 press and hold the reset button for more than 5 seconds and release it before 15 seconds. While holding the reset button for more than 5 seconds and less than 15 seconds the Power LED will be blinking at about ½ second intervals. After releasing the reset button the Power LED will blink 3 times rapidly then go off. A few seconds later the power LED will come back on and a channel is selected.
- The sequence of manual channel selection is: 1,6,11,5,10,4,9,3,8,2,7,1 (switching from auto channel selection mode to the manual channel selection mode, it will always start on channel 1 and cycle through the sequence listed above every time the reset button is held for more than 5 seconds and released before 15 seconds)
- Use the Display channel to confirm the channel that the Master is set to and confirm the Slave is also set to that channel.

Please note that your environment may affect your wireless performance (ie: number of walls, distance, etc).
