2. Power up

Approximate time: 1-5 minutes

Note: Your Wi-Fi Gateway is now powering up. During this time (up to 5 minutes), do not unplug the power cord or the green data cable, as this can permanently damage the Wi-Fi Gateway and significantly delay your service activation.

For U-verse TV, restart your TV receivers after the Service light is solid green. Go to each TV and hold down the Power button on the U-verse receiver and DVR for 10 seconds.
