Hello I have an AV2000 Powerline kit that I'm currently using to connect my modem that's in one room to my router that's in a completely different room and so far it's worked fantstically for that purpose. But there's one room that gets horrible connection on my wifi 5.0 network. Since my router is only using one ethernet port on my TL-PA9020 to connect with the modem, can I use the second ethernet port to go from my router to Powerline WiFi range extender in the room with the poor 5.0 connection? All Powerline adapters including the WiFi range extender are all AV2 devices. I would imagine that it should work no problem. I just want to make sure there's no caveats to the different ethernet jacks on the TL-PA9020 that I'm not considering. I apologize if this has been addressed already, I did search for it. Thank you in advance for any help.
