You have a problem with your Wi-Fi Booster? First try the following solutions:
Restart your Wi-Fi Booster by pressing the Power button to turn off the device, then pressing it again a few seconds later. The Power LED doesn't light up? Check that the Wi-Fi Booster is connected to an electrical outlet.
Verify that the switch on the back of the Wi-Fi Booster is in the AUTO position, unless you have connected it to the modem via ethernet cable (in this case, the switch must be on Access Point).
