Hi

I have a home office at the top of my garden and a Deco P9 network throughout the house. The wifi signal to the office is quite weak and I am looking to provide something much more powerful outside. 

My question is whether using a TP-Link EAP225-Outdoor AC1200 MU-MIMO is the correct solution. If so, do I just plug in a network cable from a P9 unit into the EAP225 or do I need some additional hardware? The description I can see shows that it has Power over Ethernet which is making me think I need something additional to provide that power.

TIA

David
