Pls post even logs.

 

#1. Most likely one of of your US channels has noise and thats why you may be seeing 1 missing US channel.

#2. Your DS channels have noise and thats why you are seeing uncorrectables.

 

You may want to fix your cable. Do you have bad cable, connector or bad splitter at home?

Thanks for the reply.

I live in an apartment and the cable comes from outside wall into my living room.

I tried to see where the splitter is located but I could not reach it. It is in between two buildings in a narrow alley.

But pretty sure splitter is used. My landlord downstairs also has optimum. As far as I know they have no issue.

 

Please see logs:

    If you see your log, there are lot of T3 and T4 timeouts. they will cause intermittent disconnects. 

     

    Have you looked at the connectors at your house? are they are in good condition and not loose, etc?

      Hi, only have one connection in my house. It is tight on the inside of the house.

       

      Not sure what is going on outside.
