Ubiquiti Access points are pretty nice, and good bang for the buck; but I’m not a fan of any of their core hardware.
The only mesh I’ve ever played around with was ASUS’ AiMesh built into their routers (three RT-AC68U’s in this case) actually worked pretty well when we were playing around with it, but that was more for shits and giggles.
Now many routers are not reliable. Even new powerful models may not help you. It is better to contact those guys who connected the Internet to you. My uncle had a case when the Internet was working slowly at home and he decided to try to restart the router, but it didn’t help. Then he told me about his problem and I asked him, turned to the employees who installed the Internet for him. They came and changed his router, but it didn’t get any better. Then I decided to go to https://192-168-1-1ip.mobi/192-168-1-254/ and see the settings. It turned out that the system was not fully configured. Now everything works fine for my uncle.
I totally get you. Some mesh networks have trouble with certain routers or smart home gadgets. If you have IoT devices or a server from your ISP (like Verizon or Sky), make sure the mesh system you choose works well with them. I’d recommend the TP-Link Deco X60, it’s more affordable but still reliable. Deco X60 | AX5400 Whole Home Mesh Wi-Fi 6 System | TP-Link Philippines
I get why you’re not sure about mesh networks. There are scary stories about unstable connections, moving between nodes, and firmware problems. Luckily, there are a number of reliable mesh systems that, when set up correctly, can provide fast, stable connections. One example is the Deco whole home mesh WiFi system from TP-Link which is affordable yet provides reliable internet. https://www.tp-link.com/ph/home-networking/deco/
