You can try swapping out each of the wall wart power supplies to see if it makes a difference. Your cable lengths in a house should be short enough that power budget is not an issue unless one of the modems has an issue or the power adapter has an issue. You may have to go to each node, if one modem does not report both modem's values. IS there any report of the power budget used/avail on the modem diagnostic pages ? The barrel connection should be between 3.5 and 5 dB at MOCA frequencies. When you removed the splitter, you removed about 10 dB of signal loss in the path based on the Holland spec sheet for insertion loss at MOCA frequencies. If the issue is with all ports, then there is likely too much signal loss for that path and you will need to get a 0 loss MOCA2 powered splitter or a minimally amplified MOCA2 splitter. If the issue is only with one pair of ports or a single port, then replace the splitter. It can also be an issue with the termination of the cable end. Sometimes it is just how well the connection is made between the cable termination and the receptacle rather than the splitter itself. One test would be to hook up the other room cable that has not shown an issue to the "bad port" and see if packet errors are reported. Then repeat except using the other cable. Disconnect power to both modems and then connect power. Take the two cables of concern, keep one at a constant port on the splitter and move the other one to different ports. See if the bad packets are associate with specific connections on the splitter or specific cables. I don't know what the 1-2 msec lag will do to your gaming, but i would be surprised if it caused packet loss. You could get a 25 ft or whatever length you need of pre-terminated RG6 and test the modems alone to see if it is in that part or the in wall coax plant. I suppose it could also be an issue with one of the modems as well. You may be able to pull the wall plate and connect the GoCoax modem directly to the cable in the wall on the cable segment that shows packet errors. Most likely it is a termination or possibly a slightly loose connector on the wall plate. Of course that doesn't tell you if it is the coax or the terminations. To try to track down which segment of cable might have an issue with packet drops, you will have to pair up two GoCoax and run the test over just one segment of cable. You can either use a RG6 barrel connector (union) to connect the two coax or get another GOCoax modem and run two pairs with an ethernet cable between them. ie point to point between the two locations of interest. Run your test without the Holland splitter. You will have to isolate elements in the coax plant as much as possible to figure out where the issue is. Short of replacing the in-wall coax (at that point, I should just install CAT6), is there anything you'd suggest looking at to avoid the packet loss, or is this inherent to MoCA? Replaced all coax patch cables with new RG6.Replaced old barrel connectors with Holland 3GHz barrel connectors.Added Antronix MoCA filters to my point of entry, modem, and STB.Put 75ohm terminators on every unused coax connector.Replaced an older amplifier with a MoCA-compliant Holland splitter. I've tried quite a few things to improve MoCA performance, including: This eliminates the packet loss completely, and it prevents the teleport glitch in SMB. Presumably it never touches the MoCA network. If I move the Shield to my bonus room, I connect it to the same unmanaged gigabit switch as the gaming PC. Also, my GoCoax status screen (see attached) shows "Rx Bad" packets. Throughput is >900Mbps when I run 10 parallel streams, but the UDP tests show packet loss. I got the attached results from an iPerf3 server on the Shield and a client on the gaming PC. I use Moonlight's "Prefer Smoothest Video" mode, and the teleporting happens regardless of what bitrate I stream at (0.5Mbps, 50Mbps, or 150Mbps.)Īt first I assumed this happened because MoCA adds 3-4ms of latency, but I'm wondering whether it's related to packet loss. in an NES emulator, Mario "teleports" for a split second once every 15-20 seconds. I stream at 1080P 60FPS and it usually works great, but there are quirks that are most noticeable in side-scrolling 2D games. My network consists of three TP-Link Deco X60 mesh routers with three GoCoax WF-803M MoCA 2.5 adapters (see attached network diagram.) I have a gaming PC in my bonus room, and I use GameStream/Moonlight to stream games to an NVIDIA Shield Pro in my living room.
