Here's how to pair your Wi-Fi Extender Kit with your TalkTalk Wireless Powerline Adapters. Please be aware that your Wi-Fi Extender Kit is not compatible with any non-TalkTalk powerline adapters or equipment. Set up your Wi-Fi Extender Kit using the steps above. Plug in your old TalkTalk Powerline Receiver (the one that wasn't connected to your router) and switch it on. You won't need the Powerline Transmitter. Press the and hold the Pair button on the Powerline Receiver for 10 seconds to remove the pairing with your old Powerline Transmitter. Then press and hold the Pair button again for 3 seconds to trigger pairing mode. The Power LED will start flashing. Press and hold the Connect button on the bottom of your Network Connector immediately after. After two minutes, your old TalkTalk Powerline Adapter will be added to your network.
