From time to time with increasing frequency the phone stops communicating with WiFi or 4G. Cannot ping the gateway router on local LAN or ping google.com on 4G. Power cycling the phone restores connection and communication. Access point show connection. Gateway router shows connection. This occurs w/o notification as both WiFi and 4G icons indicate connection. Do not know if telephony is affected. This behavior is relatively recent. No apparent action seems to start the behavior. I use MightyTextPro and the PC app to Phone is troublesome when there there is communication. Any suggestions... .. ?
