BlueTooth/WiFi issues after iOS 11 update on iPhone

I updated iOS to 11 and every update since and have had nothing but issues with WiFi and Bluetooth. The Bluetooth will connect but is choppy and skips a lot, WiFi will have full signal, then drop the connection and won’t reconnect until I put in the password 5xs (every WiFi connection, any Bluetooth device). I’ve reset network settings, turned the airplane mode on, “forgot” all connections and reconnected, even reset my phone as a new one. Still no dice! This didn’t happen until iOS 11. Any help? This isn’t the first time an iOS update has messed my phone up. I am considering going to Samsung (I know this doesn’t matter to anyone, but my level of frustration is astounding).
