Hello, I am having trouble connecting my two WF-803Ms with and Xfinity XB3 gateway. The gateway supports bonded Moca 2.0 and had limited setting (Channel is unmodifiable but listed as using D1 (1150 Mhz) and with the preferred network controller setting to enabled). The gateway does not detect the WF-803Ms, and the WF-803M cannot see the gateway. Interestingly, when I remove the gateway and connect the same coax to a WF-803M, the WF-803M will see each other and establish a Moca 2.5 connection. Is there something just incompatible with the XB3 gateway and the WF-803M? I flashed both to the newest firmware (v1.0.14) and no change - can't see the gateway but will connect to each other. Tried restarting the gateways and WF-803Ms numerous times and played with the preferred network controller setting to no avail. I need three locations with network access, which is why I am trying to use the Moca capabilities of the gateway for the third (instead of buying another adapter) even through I know speeds will be at Moca 2.0 levels.
Any suggestions. All splitters are Moca certified.
When setting up the Xfinity XB3, it seemed like everything would run smoothly. However, connecting it to my MoCA network turned into a headache with constant connection drops. After trying multiple solutions, I decided to contact https://xfinity.pissedconsumer.com/customer-service.html . Their team jumped right into action, asking detailed questions and providing tailored troubleshooting steps. With their help, I got the issue resolved, but it made me realize how crucial it is to have responsive support when dealing with tech setups.
Your issue suggests a potential compatibility problem between the Xfinity XB3 gateway's MoCA implementation and the WF-803M adapters. Here are a few possible explanations and troubleshooting steps:
1. Compatibility Issue:
The XB3 uses bonded MoCA 2.0, but WF-803M is MoCA 2.5. While MoCA is designed to be backward compatible, some implementations can have issues with cross-version communication.
The XB3’s MoCA controller may be using a different MoCA frequency band or settings that prevent the WF-803M from detecting it.
2. Channel Mismatch
The XB3 locks its MoCA channel to D1 (1150 MHz), which is not user-modifiable.
The WF-803M defaults to MoCA 2.5 auto-negotiation and may not be correctly falling back to MoCA 2.0 on the same channel.
3. Preferred Network Controller Setting
If the XB3 is set as the preferred network controller, try disabling this option and let a WF-803M act as the MoCA controller.
Conversely, try enabling this option on the XB3 only and disable it on both WF-803Ms.
4. Verify Coax Network Setup
MoCA won't work if there are cable TV filters (PoE filters) that block MoCA signals. The XB3 may have an internal filter preventing communication.
If possible, check if the XB3’s MoCA network is actually active by connecting a single WF-803M to the gateway's coax directly.
Test if the XB3 MoCA network is actually running:
Turn off all WF-803Ms.
Enable MoCA on the XB3 (if it's not already).
Check if another MoCA device (like a TiVo or another MoCA-enabled gateway) detects it.
5. Check for MoCA Security Key
Some Xfinity gateways require a MoCA privacy/security key.
If enabled, the XB3 won't recognize other MoCA devices unless they are set to the same security key.
Check the XB3’s MoCA settings in the admin panel and disable MoCA security if possible.
The XB3 uses channel D1 (1150 MHz). Make sure the WF-803M supports or is configured for this frequency band. Although you mentioned that the channel cannot be modified on the XB3, check to see if the WF-803M allows manual configuration of the MOCA channel to match the XB3 planet clicker

And some more information that I left out of the original post - yes, Moca is enabled on the gateway; (Moca) light on back of gateway is even on. I do have a PoE filter installed by Comcast on input to main splitter. Again, the go coax adapter see each other right away (within 10 seconds max) but can never detect the XB3 gateway. I tried with just one WF-803M and the gateway and WF-803M Moca light will never turn on even though the gateway Moca light is on, and then with two WF-803Ms, which will see each other when but never the gateway.
