Questions: MoCA turn up and set up at new site move on August 27

Hi everyone!

I am a former network engineer that has used MoCA successfully previously at my home. I am presently moving from a townhouse with Xfinity 2G internet service thru XB8 router to a townhouse and moving service on Thursday, August 27, 2026. I understand that I have to turn on MoCA on the XB8 (as I did not use MoCA at my present Xfinity location with the XB8).

1) I assume this will be straightforward through logging into the router or do I need to involve technical support to accomplish this?

In regards to the MoCA boxes, I understand that I will need one (Xfinity compliant) for each of the three rooms that I want to have ethernet access through the present coax wall connections.

2) Is there a webpage listing Xfinity authorized/compatible boxes?

3) Do I need one at the site of the XB8 or does is that unnecessary with the XB8?

Please confirm location of any additional equipment (i.e. splitters, etc.). I have not moved in yet and have not had extensive time in the townhouse so I have not spotted where Internet service enters the townhouse.

4) I would like to know some specifics regarding if splitters are inside or outside townhouse.

5) I was planning on a self-install. Should I schedule a technician to come out to the townhouse on Thursday August 27, 2026 the date of my Xfinity service move?

Sorry for the length of message but my experience with MoCA was through an AT&T fiber network Internet connection and I want to be sure that I follow Xfinity standards/guidelines/best practices for my Internet service at my new location. Would appreciate any assistance here ahead of my move on August 27.

Thanks,

@user_a5ctvh Thanks for adding a post to the forum. Once the service is installed, you can enable the MoCa setting through the Admin Portal. It's a good way to use your service if you choose. That may not be immediately available though, so you want to follow the steps here https://www.xfinity.com/support/articles/admin-tool-access. Once the Admin Portal is enabled, you can use it to enable the MoCa setting under Connections. A filter on the modem is recommended usually for best performance.

For any additional equipment, it would be up to the home owner, and what they want for their network. Customer service agents do not have any insights to the property, or the connections. That includes any wiring, splitters, or where service enters, and how it is managed inside the home. The home owner would need to do that onsite to learn how everything is set up. Agents are able to see the equipment that is assigned to the location, and their health. The length/condition of cables, or if there are splitters is something agents usually ask customers during troubleshooting.

We always recommend a self install as it's free, especially if the home had Xfinity with the last owner. A technician would be great to install the service if you're not comfortable with it, but they would only make sure the service is active and working. It would be up to them to coach a customer on how to add or manage a MoCa network. Not to say they wouldn't, but they're not required. If you need more info to feel secure about using MoCa at the new location, there are many posts here on the forum with guidance from community experts. If you have any questions, or other concerns before getting started let us know.

Thanks Benny,

I have a couple of possible complications in that I do not own the townhouse but am on a yearly lease. Also my townhouse is one of 5 or 6 on the block and they are all attached. I just came back from viewing the property and still am not sure where the Internet entrance is for my townhouse.

I believe that I will probably require a technician to identify exactly where outside the Internet entrance to my townhouse is and check if there is already a MoCA/POE filter installed.

Question: If there is not one installed would Xfinity tech be able to provide it for installation or do I need to purchase it for installation?

Thanks again for your response!

@user_a5ctvh When it comes to town houses, they usually have a community set up / lock box that is used to distribute everyone's service. It's either connected by a pole to the building, or underground up the side of the building. Usually in the back or sides. You may or may not have access to it as the tenant, but should be able to verify. To make it easy on customers, the filters are always recommended to be placed on the back of the modem.

If you think it's worth the professional install fee, we can help modify the order if you need. However, they only need to make sure the service works with the default network, not help enable additional networks in the home. A tech providing suggestions or helping with that would be them going above and beyond. It would be a sure thing to pick one up for free at a local Xfinity store, or purchase one from a hardware store.

It would only be a sure thing for a tech to take one if the location is causing signal issues, or leaking interference to the neighbors.

Do you want help with modifying the order? I think you'll be good without it considering your prior experience and skill level.

Benny,

I am comfortable with installing the MoCA adapters and splitters where necessary but the big issue is the MoCA/POE filter location. In reviewing the property again it appears that all electrical and communications facilities for the townhouses on one side of the block are connected at facilities at the outside wall of the first townhouse on the block. It does not appear that I would have access to install the MoCA/POE filter there.

What I am hoping is that the install tech would be able to identify where the Xfinity connection comes into my townhouse and access that Xfinity communications block (for lack of a better word) and install the MoCA/POE filter that I would provide or at least determine if one is installed.

I read where the HOA may need to give permission but since this a security benefit I am not sure why they would decline but I cannot ask for permission if I don't know where the entrance facility is and if a MoCA/POE filter is already installed.

Please advise if this is reasonable. I can handle all of the internal portions of a MoCA install.

@user_a5ctvh What you're essentially asking, is for the tech to enable a different network than the default one. That isn't part of their required checklist to complete an installation, so we wouldn't hazard expecting them to do so. Getting to the lock box, or accessing it may not be possible for everyone, that is why it's recommended to place the filter for MoCa applications on the back of the modem. Techs normally reserve placing a POE filter on the property when the location is interfering with the neighbors. That is the common application for a filter from a tech perspective. You'll still have to pay for the professional installation of them connecting the modem in the home and confirming where the building connects to the service, even if they don't have a filter or provide any coaching on how to enable the MoCa network.

@user_a5ctvh You can't put a MoCA filter at the back of the gateway if the gateway's built-in MoCA feature is going to be used. It needs to be at the demarc.

As stated. If you place it at the back of the gateway, the built-in MoCA feature will not function. You could try without any filter at all, but it's a potential security risk for both you and your neighbors. No matter if you use the gateway's feature or a standalone adapter, any MoCA network should be protected with a PoE filter.
