I have a ASK-SFE116 Verizon 4G Extender that is approximately 18 months old. Has worked fine for the last 17 months. We have not changed anything with our ISP router or location. Today it keeps rebooting when connecting to the HEMS/HEGs server. All firewalls are turned off on the routers. Service says Inactive/Open. I have tried unplugging it for an hour, have tried Factory resetting it numerous times and it keeps rebooting. If I cannot get this to work I need to change carriers as I get almost no signal in our house. I have made multiple attempts to call support and spent over 15 hours with them and it is still doing the same rebooting continuously. Is this just an extender that failed after 18 months?
