How to add an extra powerline adapter to the existing powerline network with pair button?

Note: We only need to have one of the powerline adapters(Wired units) plugged into the main router with the Ethernet cable directly, then pair the other units with this powerline adapter.

In this scenario, Powerline adapter A and Powerline adapter B form a HomeplugAV Network, Powerline adapter C wants to join this network.

The following steps are suitable for:

TL-PA211, TL-PA201, TL-PA210, TL-PA111, TL-PA101

Step 1 Press and hold the Pair button on Powerline adapter C for 3 to 8 seconds.

Step 2 Press and hold the Pair button on Powerline adapter A or B for 3 to 8 seconds. (This step must be taken within 120 seconds after step 1 is finished.)

Step 3 Wait for about 60 seconds while your Powerline adapters are trying to connect. The Power LED on Powerline adapter A/B and C will stop flashing and become solid light when the connection is made successfully.

The following steps are suitable for:

All Powerline adapters except the models mentioned above.

Step 1 Press and hold the Pair button on Powerline adapter C for 1 second.

Step 2 Press and hold the Pair button on Powerline adapter A or B for 1 second. (This step must be taken within 120 seconds after step 1 is finished.)

Note: The sequence of step1 and step2 mentioned above can be exchanged.
