2 x 2 Port Powerline Adaptor - Router Setup
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Note: This is for the TL-PA7027P Kit.
I have a kit of 2 x AV1000 - each with 2 Ethernet ports.
I had assumed that this was 2 different channels, and required 2 connections to my broadband router.
However, recently I had some issues with the home network, which I identified as being caused by a loop, so started investigating.
Based on advice found on a Virgin support blog (search for "Virgin Supehub 4 and TP-Link TL-PA7027P")
I unplugged one of the connections from the router - and EVERYTHING kept working with my power line plugs, and the network issue was resolved.
This is the correct setup - and it turns out that "spare" port on the inbound adaptor can be used as an "output" for another machine:
Hope this is helpful to others - might be good for TP Link to be more clear about how to set up the multi-port adapters!!!
Hi @mrNo1r
Thank you for sharing your finds here! You are right that only one Ethernet cable between router and powerline adapter, two Ethernet cables may cause some loop in the network.
It is also welcomed to share your thread explaining the correct network topology in the Story here so its easier to find and could help more users!
