Fiber mesh

I’ve been told that I can’t make a mesh network work with the newest infinity xer10.  The last person I talked to from technical support said he’d put it bridge stays for me and it’d work.  After an hour and forty minutes he kicked me back into the cue.  Has anyone figured this out? I’ve been to the store (no help) the sales guy who said it would work (no help) several calls to tech support (no help).  At this point I’m ready to give up and switch back to my old provider.  The xer10 hardly covers any of my house and I was told it would cover my backyard as well.

@user_9zovgo  I understand the frustration that’s a lot to go through.

Your gateway can work with a mesh system, but it needs to be set up correctly. To use your mesh, the gateway has to be in Bridge Mode, which turns off its WiFi so your mesh can take over. If that didn’t fully complete (or something like xFi Pods is still active), the mesh won’t work properly.

The coverage you’re describing is exactly where mesh should help it just sounds like the setup didn’t finish correctly. Have to checked settings in our Xfinity APP?

The XER10 doesn't have a toggleable bridge mode feature.

I suspected that was the case.  I went through the steps in the app and also through the admin tool and there isn’t an option.  Are there any others that will work with the fiber connection and can be put in bridge mode?

Hi @user_9zovgo,

I am one of the rare folks that also has a XER10. Unfortunately, this device cannot be put into bridge mode. If your mesh network is router based you will be unable to complete the setup of a mesh network. I would recommend taking a look into the Xfinity Wi-Fi extenders, the Xfinity Wi-Fi Extenders FAQs does a good job of answers commonly asked questions about the extenders. 

To answer your other qustion, there are curreently not any third-party modem or routers that are compatible with our Fiber network. Does the XER10 seem to have any connection issues, or are you just experiencing coverage issues?

Coverage issues.  What about using the XB8?  I have the  TP-Link Deco XE75 AXE5400. Would I be able to use that mesh with the XB8 off fiber?

It is my understanding, and I've also seen many posts here, indicating that 3rd-party routers can be used with the XER10 placed in a DMZ. Their fiber-based systems use the (DPoE) Docsis Provisioning over Ethernet protocol for management and authentication purposes with the XER10. You just can't connect a 3rd-pary router directly to the ONT (Optical Network Terminal)

You could use their XB8 device but depending on your subscribed to speed tier, your speeds may be limited. You could also use your own 3rd-party router and place it in to a DMZ to avoid an unwanted double-NAT condition, which occurs when cascading two routing devices.
