I had many wifi issues due to the layout and structure of my dwelling, and Unifi was the only setup that solved them. I started with my original Orbi (Voxel firmware) mesh setup from my previous home, but performance wasn’t where I wanted it due to the age of the devices. Then I tried the TP-Link w7200 sets from Walmart, but it didn’t meet my needs connecting a remote building on the property.
Unifi are expensive, but I have no regrets. Even added their security cameras to my network when the old system needed replaced.
