I'm experiencing latency spikes on my MoCA network and I could use some help. My ISP is Spectrum, but my Xbox is in a different room from the modem, and using Wi-Fi alone just isn't cutting it. To improve things, I've set up MoCA using coaxial cabling. Here's the layout:
- The internet line comes into my apartment through a wall panel with a POE filter for the MoCA network.
- Splitter 1 connects to two wall panels: Room 1 and Room 2.
- In Room 1, I have another MoCA-rated splitter that connects to my modem and Router 1 (an Eero Max 7).
- Router 1 is also linked to a MOCA 2.5 unit and my desktop computer via a hardwired connection.
- In Room 2, there's another MOCA 2.5 unit connected to Router 2 (an Eero Pro 7 mesh) that feeds my Xbox and laptop wirelessly.
I've noticed packet loss occurring randomly. This morning, during a gaming session, I didn't see any issues, but I observed packet loss during a specific test on both my laptop and Xbox. The computer connected directly to the modem didn't show packet loss during that time. Here's some packet loss data I captured: https://imgur.com/a/ErkGE33.
I'm wondering if these latency spikes could be caused by some kind of interference rather than just the MoCA setup. Any insight would be greatly appreciated!

Why aren’t your Xbox and laptop wired in? If possible, plug them directly into the Eero node. Also, could you share the models of your MoCA-rated splitters? I recommend adding a 70+ dB MoCA filter on the modem to better protect it from MoCA signals.
Have you checked your network using Wireshark or a similar tool? It might help identify any retransmissions or collisions when the latency spikes occur. Let me know if you find anything!
I'm new to Wireshark, but I'm downloading it now. I’ll report back once I've had a chance to figure it out. Any tips on spotting collisions or retransmissions?
Sure! Look for repeated packets in the capture and check their sequence numbers. That usually indicates retransmission.
I can wire the Xbox, but I prefer having my laptop flexible for use on the couch. Here are the details:
- Splitter 1: Amphenol 3-Way Digital Coaxial Splitter MoCA 2.5 ABS313H
- Splitter 2: Amphenol 2-Way Digital Coaxial Splitter MoCA 2.5 ABS312H
I tried adding a 70+ dB MoCA filter but it blocked the signal. Something might be interfering with the Wi-Fi, which I haven't ruled out yet. Here's another packet loss example I captured: https://imgur.com/a/Pbfpg4o.
