Wifi Connection Lost

Just purchased the ring doorbell pro and it has worked great for about 3 weeks. Then one day it lost Internet connection. I reset this and the doorbell came back online and worked for about 5mins, it then drops the WiFi signal again connection is lost and I have to repeat this process again. Same result everytime. I have tried resetting the device, even uninstalling and reinstalling again with the same end result. Works for 5mins then quits again.
