If you want reliable Wifi at home, get yourself Ubiquity access points and throw away TP-Link. The issue is not the protocol. After many years of unplugging and plugging back in my TP-link router I know that they are cursed.
Better yet, buy actual enterprise gear even if it's a generation behind. You can find decent Aruba, Ruckus and Cisco kit on eBay going for decent prices.
