Not saying it is easily solved, but it should be do-able to put in Some programming Logic if the DC had An GPS lost signal and a Halow lost signal with a DC connection status with frozen 3 that it tries a reboot after for example 5 min, if the fault comes back it tries it two more times, if the DC connection status remains a solid 3 then it can give the current message that the router or an network/internet failure ocurred. Sure there are more parameters to make this Logic better work.
Current DC is makes the Yarbo unnessecary unrelaible, making interested people sceptic. People seeing the machine love the hardware, and to be honest me too!
Yarbo probably has a whole wishlist with software improvements. Hope they find Some time for this soon
