Yeah I’ve used them for years - I get some people have different experiences and people occasionally get lemons but I don’t remember the last time my UniFi gear was the source of an outage that wasn’t caused by my misconfiguration.
I’ve had only a simple / reliable setup experience with a great UX
Unifi WiFi has been highly reliable for me in simple set ups.
An elderly friend had high-speed Internet installed in his farmhouse. The lath and plaster walls were reinforced with chicken wire mesh, and ISP’s WiFi router box couldn’t penetrate it. I thought maybe he would need a few UAPs, but a single UAP-LR puck has been serving reliable Wi-Fi for 10+ years with no need for a unify controller. I’ve repeated this installation for other elderly and non-technical friends. I get absolutely zero service calls.
