Hello, I have a FunBox 2.0 router and 80Mbps optical fiber or something like that. And I got a DSL cable in the set, otherwise a telephone cable to connect the router to this port, which the fitter comes and installs, and I decided to order a longer cable for Allegro 10m. And when there was a storm, I turned on the router and when the storm passed, I turned it on and the DSL LED is blinking all the time as if it could not connect all the time and restarting the router all the time does not give anything, everything is connected somehow with the cable that was included in the set this gray it connects normally and it works, what should I do? Help.
