I reprogrammed an old visio today just for the hell of it and that channel shows up now.

|Installation did take about two hours. The tech checked all connections from the street and though the house. I structured wired my house about 12 years ago so I didn't expect any problems. The tech also said that this was a "36 point" job for the two boxes and Cox allocates one hour for each 12 points, so in other words 3 hours. Don't complain, I commend Cox for allocating the time to their techs so the job can be done right. What takes so long is the hardware doing it's first sync, then firmware upgrade, then I think another sync. It is excruciating! It will be interesting to see if the new hardware corrects the audio dropouts and macro blocking. I should mention the limitations after observing for about 15 minutes.|
Does that mean older (20 years) homes need new interior cable runs?
Every situation is different. Most modern coax cable is fine, but some cables have more roll off at higher frequencies than others that will result in the higher channels with less signal at the receiver for those channels, and too much signal for the lower channels. A bigger factor is the passive devices used in the home, such as splitters, connectors, etc. A potential big problem for homeowners will be situations where they bought some sort of house amp that is only rated to 750 or 860 Mhz and have a sharp rolloff after the stated spec. I've seen homes and situations where there is a 20 dB swing from the lower channels to the upper channels due to cabling and devices on the lines.
Yes there is a professional installation fee required, fees vary by market. $50.00 to $99.00. Time allotted for installation is 2-3 hours.
If your interior wiring, coax, is not RG6 and pristine, meaning no kinks, splitters, frays, it will need to be replaced. Any RG59 coax may also need to be replaced. All terminal connectors will need to be replaced all coax and splitters must be able to pass 1GHz signals. Some homes, mostly newer, where no modifications have been made to the coax should not need much extra work.
A special trap is also placed at the demarcation point to keep your network from leaking back to the pedestal.
Here is a really good Article regarding MoCA Home Networking. "Testing And Deployment: Making MoCA In-Home Networking Easier"
Wow... nice reply.....
thanks... yes all my cabling was done by me using the best RG6 i could find. All runs are pristine.
How do the 2 boxes communicate with each other?? are they physically connected to one another or is a splitter put in to branch off?
I have another TV in the house right now which will not participate at all with an HD or DVR services... just the basic cable service over line to the in TV tuner.
Right now i have a main line coming into a 3way splitter... one goes for main room (which is where the host DVR will go )..one line for upstairs Bedroom. (which is where the client box will be going) and one for the basement which is TV straight tuner function.
How will this type of set up be wired? so both new host/client boxes can talk? and downstairs TV will be able to function with no restrictions as it does now?
The two boxes communicate just over the Coax. Most likely Cox will "Certify" the entire home, so that if you add more equipment later everything is already tested.
It is a bit technical but the article is very informative for more info on MoCA Home networking:
Awesome thanks..... i'm thinking that perhaps the only hold back for this whole thing may be the actual cable coming from the COX box across the street... all underground cabling that i know is original when house was built back in 1986. I'm sure it is not the most up-to-date coax.. and that perhaps may be a problem.
This video may also help explain things.
