Remote Router

[redtop1]

My Router is in Office  Outbuilding remote from my house (Around 10  metres,)

I want to maximise WI FI signal to Smart TV in house.

Tv is on separate Circuit and Breaker to Router and cable not an option .

I have a TP extender but weak signal.

Can I just get another Extender to use with existing or buy a more powerful one.

Your best option would be to run a cable from the router to an access point in the house, but as you said this isn't an option the next best option would be to use a Point 2 Point system. Basically a wireless link between 2 buildings, then connect an access point in the house. 

The Ubiquiti Nanostation's are great, but require a little technical know how to set up and get working. You'd need 2 nanostations, one for the out building, and one for the house. Connect one nanostation to the router using a cable, and the other to an access point for the house. You should then have a decent speed wireless connection from the outbuilding to the house. 

Point 2 Point devices require a clear line of sight to work, so obstructions such as trees and walls may prevent them from working, so you would need to place them on the outside of each building.
