Hi

For my Two-Storey 6-rooms solid brick & concrete wall house, I am looking for a good Wi-Fi system. I have Gigabit Ethernet in every room in the house, so backhaul is not a problem. Currently I am using 4 separate TP-Link Wi-Fi routers which are turned into access points. Connection with Samsung Phones & iPad are spotty and not seamless roaming between rooms. Any recommendations?

I am considering TP-Link Deco X20 or Netgear Nighthawk Whole Home Mesh WiFi 6 because they seem to provide Ethernet backhaul. I saw suggestions to use Ubiquiti Access Points or Ruckus, I am not aware how they work, do you need special controllers to configure the APs in the house.

Google & NEST Wi-Fi are double the price in Amazon India. Google/Nest & Amazon's EERO are also not officially sold in India. I don't want to have any home automation or smart speakers (think Alexa or Google) features, even if they are there, I will be turning them OFF.

Any recommendations?
