I also have the DNS panel in the “Broken” state.
All DNS, including Google and Cloudflare, are in Error with “Reverse lookup failed” indicated
In this condition the whole network is stopped and I am forced to activate all the PCs on the router.
If we connect directly to the router, with the cable or with the Wi-Fi, we navigate without problems, so it is not a line problem.
My router is a Teltonika RUT950 and uses a Vodafone SIM for 4G connection and we have been using it for over a year.
Its internal IP address is 192.168.43.1 and Red’s address is obviously 192.168.43.2 with the gateway on 192.168.43.1.
