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.
Or better yet, Aruba Instant On. Enterprise hardware for SOHO money, truly plug and play, rock solid, no tinkering involved (which can be both good and bad depending on one's goals).
