Mesh is awesome with wired backhaul (connecting them with ethernet back to the main one) and 'ok' depending your house over wireless backhaul.
If you want to solve it forever, get two or three WiFi 6 mesh pucks from TP-Link, Asus et al and wire them together. I ran external cat6 between my three.
It will completely and forever solve the issues you're having.
