My WiFi send to drop every once in a while. It drops for a very short time enough that it doesn't really effect regular internet use for streaming but I do online gaming so as soon as it has that hiccup I just get disconnected. It usally happens about every 10 minutes but then there's days when it doesn't happen at all.
There are other options. Google for WiFi repeaters / range extenders, WiFi mesh systems / pods, powerline ethernet adapters, MoCA adapters. Good luck !
