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.
It's tough. On one hand side, TP-Link has some weird issues. On the other, I spent a while debugging an issue with their engineers and they seem to actually care to improve things. Maybe the lower price is worth it sometimes.
