wifi boosters , mesh, powerline kits : getting better

Hi guys.Whats the current state of wifi coverage bosting tech, to remedy poor coverage ?**** please dont say run cables. If I could run cables everywhere this would be a non issueWith Many newish homes, running cables & cutting holes in walls etc just isnt an option

Ive installed a few powerline kits at various sites , them are OK, but far from perfect

Have boosters & repeaters become any better ? Ive never had much success with those in the past.

I see some ISPs now offering ~mesh~ kits . What the real world experience with those ? If its a house/building with realwifi degradation through walls, will mesh will still struggle ?

There a company thats been advertising on the radio : guarenteed better wifiLooking at there site, they are relying on running network cables: so thats a fail, in many homes it cant be be done without ugly trunking runing up wallsand across ceilingsThat also claimed "capable of transmitting data at a rate of 1300Mbps" . Is that just marketing BS ?

Is handoff between access points/mesh nodes etc still an issue , or is that more or less solved now.Ive seen mesh systems where Ithings would stay connected to the weaker more distant node, requiring the ithings wifi to be cycled off/on . People just expect wifi that allways works, everywhere . Trying to tell them its not realistic seems like you're making excuses
