OTA MoCA Problem

You might call TWC and ask them to put a trap on your internet feed to block the lower channels. I believe ch 2 - 13 are the same for cable and OTA, but don't quote me. The lowest frequency is 54MHz, so that is a typo with the 20 MHz, or did I read it wrong?

 

Hi Tim,
I have a suspicion that you may be getting interference from those MoCA adapters. For a quick troubleshooting step, just temporarily cut off the power to the adapters and see if your missing channels come back.

The only place the TWC feed needs to go is into your cable modem. I'm not sure why you would distribute the cable signal around your house.

 

Yeah, but the cable coming from TWC has nothing to do with MoCA. You should have a TWC cable that plugs into your cable modem. Then you have a line that comes from your antenna and splits off to the MoCA adapter and the other rooms. The two systems do not need to talk to each other. The link between internet and your MoCA adapters is the ethernet line between MoCA and the router.

 

That requires coax, but the TWC signal doesn't need to be on it. The simplest solution is what JoeKustra suggests: have TWC put a trap on the line to block the lower frequencies. Alternatively, you could run a separate coax to the cable modem and reserve your existing coax for OTA and MOCA.

One way or another you need to get the cable signal that is in the OTA frequencies off the coax that runs to the DVR.

 

You could try a DirecTV Band Stop filter. The DECA version of MOCA that DirecTV uses operates in the OTA band (as opposed to above the highest cable TV frequency), so they sometimes need to filter this band from their older equipment. It might be worth $7 or so to see if this saves having to run another wire. It available from Solid Signal for $6.99 plus tax and shipping: http://www.solidsignal.com/pview.asp?p=BSFR01&ss=488104

 

Okay now I understand. I thought you had TWC and antenna coming into the same room.

 

Hey Tim, try this. Call TWC and thank them for the free TV, mention you're are going to post on FB that they are really nice, and that you are going to tell all your friends.

You should see a trap installed in a few hours.

 

I am looking for similar help. I have a Roamio OTA and use TWC. Each has it's own coax line. At no point are they shared. My OTA signal is distributed throughout the house to five different locations. My OTA signal is very strong and I pick up all Los Angeles OTA stations. The Roamio OTA DVR is located near the downstairs Family Room TV. The TWC internet cable is located upstairs and is connected directly to a Modem/Router combo. When I signed up for Tivo, I purchased two MoCa adapters but could not get them connect a MoCa network. I called Tivo and they told me that the TWC and OTA cable must be on the same coax and I should consider using a combiner. I have not tried this as I have no easy way to get the OTA coax to run upstairs to the modem/router. My goal is to add a mini to the master bedroom TV. Any help would be appreciated.

 

This is one of the best setups.

This is one of the worst setups, and could break what you already have working. Some people are lucky and it works anyway though.

It's possible to use a diplexer to run MoCA on a shared video signal line. It's hard to make a exact suggestion though, without knowing what cabling is already in the "target" room, and the "source" room.

 

Source room: Ota coax connected to outdoor antenna. TiVo Ota is wirelessly connected to home network.

Target room: Ota coax connected to outdoor antenna. I want to add a mini to this tv. It currently receives Ota reception directly from the outdoor antenna

Neither source or target room have hard wire Ethernet connections. TWC Internet is connected to the modem/router in my upstairs office. TiVo Ota is wirelessly connected to this network. I also use a wifi extender in the living room for better TiVo Ota signal strength

Hope this helps paint the picture of my setup.
