My mates mother in law's zgemma 2s has lost its internet connection and is showing the no internet message on screen. He's checked the connections and rebooted the router but nothing changed. I've told him to reboot the zgemma next time he's at her house but I'm wondering if there's anything else he can do? The led lights on the Ethernet port are on but not blinking. The box is running wooshbuild v5. Thanks in advance for any ideas.
