Due to my house being older and somewhat solidly built I've had continueing issues supply a solid WiFi signal to all corners of the house.
With the prolification of predon=minantly Smart TV's I found that mine, in many locations really struggles with WiFi

I installed many so called solutions with the best results provided by DLink DHP 1321 coupled with a Netgear EX6100 Range extender.

That was till I found the Ubiquity range of products, specifically the Ubiquiti UniFi 802.11 AC PRO Access Point

This is the coverage I now get.
