Yeah, I've tried tp-link, d-link, netgear (consumer), and they're all really bad. Each time I think I've found the silver bullet, but I keep hearing how good Ubiquity is. I know they're not defying physics, but I'm sure that as they aimed at commercial then I'll hopefully be getting something way better than what I'm getting now.
I think this plus laying cable should last me another 10-20 years
In my neck of the woods (France), Ubiquity is fairly expensive. I've had good results with a cheapish (~100 €) netgear "business" access point, the wax214.
It supports poe, wifi ax (but only on 5 GHz), wpa 3 and can broadcast 4 separate networks, each on its own vlan (but it doesn't do any routing). It's been great for random iot junk that I don't want on my main network.
Routing is handled by an old HP elitedesk I've saved from the bin at work.
