Mesh system (TP Link Deco) - one ethernet for input and one for output?

[Filingo]

The TP Link deco has two ethernet ports:

 

Is one of them for the input from the wall - then it transmits wifi, and the second one for output, say for a computer/switch?

 

Because I need both wifi and cable, so it could be a good solution

I have these, the ethernet is for backhaul so if a cable broke it would have no downtime or issues along with second optional routes. You can plug stuff into these ports as well. So I go from my router into one then into a switch. But I also have some things plugged into the ports in other rooms.

Yes. One is modem WAN input, and one will be LAN… I assume.

 

Also just or note, I have had great luck with Nest Wifi (formerly google Wifi). Have it deployed at multiple family members houses and it works great.

Can you please provide a link to Amazon? To be sure it's the same one I saw

so it can both be from the same source as backup, and if you plug one to it for source and out from it to a PC it automatically detects it? nice
