I upgraded to 1Gbit and a technician from Guidon installed the new media converter last week and things were working good. However since this morning I don’t have an internet and I see that the PON light is flashing. I called the customer service but didn’t get much help, they said I need a visit from a technician and until now I haven’t received any communication to be able to make this appointment. This causes a lot of annoyance as I work from home and rely on being online all the time. I also read on this forum that a flashing PON light is not something that can be solved at home, so will the house visit even help in this case ? Also anything I can do here to have a faster resolution ?
