I have a new solar battery installed at my house. But i cannot believe it does not have a wireless connection.

So i find myself in

the situation where i have a rj45 network cable in my garage and the router is the other side of the house.

I currently have a TL-PA9020P AV200 2 port kit working from my router to one of the bedrooms.

I want to add another to resolve my issue.

BUT do i need to add 2 new devices (one being connected to my router) or will just a single one work. Also does it have to be the same model. This is purely for monitoing purposes. so not real bandwidth or speed needed.

I really look forward to your thoughts, advice and comments.

Thanks in advance
