My configuration has an XFinity Modem/Router device (CISCO DPC3941T) configured in the network and I enabled the MOCA Network option within it. For the last few months I have had an ActionTec Network Extender (ECB2500C - Not Bonded) configured in the granny flat on the property and working fine (200ft away and the original line was I believe installed by Comcast before we arrived). I have recently added a second device (ActionTec Network Extender ECB6200 Bonded MOCA 2.0) onto the network in the house and internet access through that has been working fine. I have now found the original device can't get a connection through the COAX (light is no longer lighting up for it). I tried replacing the older ECB2500C with a newer ECB6200 but I still couldn't get that to connect any longer (still no COAX light now) and no internet access. I tried unplugging the newer ActionTec ECB6200 in the house to see if the older ActionTec ECB2500C from the granny flat would show up on the XFinity router/modem MOCA Troubleshooting page, but no luck (I haven't been back to the granny flat yet to recycle the power for that device when the newer is unplugged yet).
It appears to be rather finicky as to when a second device will work, and I haven't been able to work out an order or situation yet that specifically works. I have been trying to get a second one in the house working (of either model), and some times they will, and sometimes not.
Just in case it affects the picture, due to our location we have a "COMMSCOPE AC Adaptor" (CSAPAE415V500) to boost the signal in the Coax to get anything to work (including the initial XFinity modem/router). This was already here when we arrived so I assume a Comcast component from the previous owners. Could these devices be putting additional load on the network making it tough for a second MOCA network extender to work? Perhaps needing a second COMMSCOPE AC Adaptor? I wouldn't have thought so, but I am a little out of my depth here.
Ultimately I expect to need 3 MOCA network extenders on the network to best provide support, so I would really like to work out what else is needed to have this work.
Any suggestions on what to try?
If this isn't an expected configuration for XFinity with MoCA, is there something you can point me to that indicates what is?
Are all splitters, if any, MoCA compliant? Is the amplifier MoCA compliant?
I am checking with the manufacturer of the amplifier, so hopefully I would have an answer in the next day or so. The only splitter visible inside the buildings is between the Modem/Router device and the network, so everything was going through that when it was working in the other location, and currently to the new location. If there are other splitters they are in the walls or under the house and were cabled by I believe Comcast before we moved in. I will take a look at all that tomorrow in the light to see what I can see.
This was a self install on my part, so is this something that a Comcast technician would be able to help with if they were to come on site do you think?
Also, I know the MoCA POE filter isn't currently installed, could that also affect this?
I only found two splitters in the configuration, but also found a second Commscope component. Commscope are painful getting any information out of regarding these components and how well (or if) they should work with MoCA, and I am still waiting for a straight answer.
I removed one splitter from my network and replaced the other with a MoCA splitter and still found the configuration was only supporting a single MoCA/ActionTec network extender. This was all using the built in MoCA capability in the XFinity/Cisco Modem/Router combo. I finally turned the Cisco MoCA support off and placed an ActionTec component coming from the modem back into the Coax network and all seems to be working fine now for the two remote ActionTec Network extenders and network connectivity. Seems like the Cisco router support may not be that great for more than a single device, or over a certain distance (the second location has over 200ft of cable from the modem/router). For what it's worth, the Commscope components seem to be working ok in this configuration as well. I am dissapointed with the XFinity/Cisco Modem/Router though.
Thanks jweaver for your comment. I have the POE filter here, and have tried to install it at the point where the cable comes into the property, but the person who originally tightened those cables did a very good job.
Considering the modem/router could be anywhere in the household, how does having a filter in it help? I understood the POE filter needed to reside at the entry to the house to prevent those from outside the house gaining access to your network, and thus everything after the filter in your network is secured.
