Comcast modem no longer working when using MOCA

[jalopez]

Hi,
I recently starting experiencing some issues with receiving certain channels on my Tivo. A few channels had no signal and HBO HD was coming in totally pixellated. I spoke with comcast CS and they rebooted that cable card which was no help. I decided to replace the coax cable that was running from the 2.4ghz splitter to the Tivo (it was this super skinny coax unlike a standard cable) and that did the trick. However, now my Cable modem is no longer working when going through the MOCA adapter.

The cable modem does work when I go straight into it, bypassing the MOCA adapter. I tried also replacing the coax that connects the MOCA to the cable modem but that didn't work.

The cable modem has a 'US' light which blinks and the ready light never comes on.

When I was checking all the splitters I noticed that I never changed one of the splitters (5-1002mhz) and I wonder if perhaps that's the culprit. It's strange that simply replacing a coax cable would cause all of these problems.

Any suggestions?

You've got a lot of cascaded splitters and the cable modem signal has to pass through two splitters, one of which does not pass MoCA signals and the internal splitter in a MoCA adapter.

I don't know why replacing the cable caused your setup to not work. But the signal to the Cable modem was probably borderline as it was.

Get the splitters out of the way of the cable modem and replace that 1 GHz splitter with a 2 GHz. Actually, while you're at it, just get a three or four way 2 GHz splitter and simplify.
