My A55 5g is just a week old. It connects to WiFi network ok with internet access but then, randomly, will drop the internet leaving me with the message "connected without internet". Turning WiFi off and on still leaves "no internet". Only cure is turning the phone off then on. Trouble is, the fault is random so it's a real pain having to keep checking if I have internet or constantly turning the phone off and on. It seems this was a common fault with previous A models
