Hello:
After doing extensive troubleshooting, I didn't find anything unusual in the cables and connectors.
Then, I decided to open the ONT and found an amber light in the MoCA connection status.
I connected my router directly to the ONT and still got the amber light. Tried with another router, same result.
So, at this time I suspected that someting was wrong with the ONT and decided to call Technical Support. After a few questions, they decided to send a technician. After a quick check up, he decided to replace the ONT. MoCA connection status light is now green and last night all HD channels were visible again.
Thanks for your reply.
