It’s often the case that techs direct-connect the modem to the incoming provider line, and disconnect all other coax lines. the first thing to do is determine whether the two coax outlets are even interconnected. Another would be disabling MoCA in the gateway in favor of using another MoCA 2.5 adapter as the main MoCA/Ethernet bridge, bumping shared throughput up to 2000 Mbps (2500 Mbps TURBO).īut I wouldn’t necessary head down either path until incompatibility is confirmed. It’s not impossible that there’s a compatibility issue, as there have been reports of the MaxLinear 2.5 chip having issues with older Broadcom MoCA 2.0 chips.ĭowngrading the MoCA 2.5 adapter would be one option. Should I just get a 2.0 adapter instead of this 2.5 one? Supposedly it's backwards compatible but I'm seeing some people say they've had issues. To be clear, its built-in MoCA bridge is standard MoCA 2.0, so shared throughput with any standard MoCA 2.0 or better MoCA adapter will be limited to 400 Mbps (500 Mbps in a 2-node only “TURBO” setup). This modem/router has MoCA capability at 2.0 (see here and here)Ĭomcast/Xfinity TG1682G. The frequency spec isn’t determinant for splitter MoCA compatibility. I looked at all the splitters in the system and they're at least 1000MHz. u/RoweDent created this awesome resource on network theory u/tht1kidd_ has created a suggestion post regarding information everyone needs to provide when asking a question about their network There have been some excellent guides written in this sub, and we're always looking for more!

I suppose the right thing to do would be to send it back. Oh, and the 8 port unit eventually arrived over this last weekend.
The area manager that was supposed to contact me 2 weeks ago finally called and committed to have an engineer check to see if any of my noise was leaking out to their infrastructure. The low-frequency "electrical" noise remained, but I'm neither sure it affects my signal nor causes problems for my neighbors. I called Comcast and asked them to check my cable plant again and they found none of the high-frequency noise they saw previously. It actually arrived on time and I installed it immediately, also making sure everything that was supposed to be terminated was terminated with 75 ohm caps. When it hadn't shown (or left Stoughton) for 2 days past its scheduled arrival I ordered this unit. I had originally ordered this unit, but Amazon managed to lose it in their Stoughton MA distribution facility. Had you bought or installed any electrical powered device at about the same time the issue started ? If it does not come back, then it may be 1) heat related on one of the devices, or 2) spurious electrical noise - appliance, motors, power supply, etc that is radiating enough to be picked up on one of the cables due to a shielding fault or improper termination. If there is still an issue it is on the comcast equipment. if the baseline does show noise issue, unplug your coax one at a time until only the power and input connections are connected. If they hook up the spectrum analyzer again, power off all of your equipment ( including the modem) connected to the amp, get a baseline reading of the noise present (since it may be on their side / or from your cables somewhere) - see if that situation has the issues, and then assuming it does not show any issues, power up the ISP devices and then your devices, starting with the modem, one at a time until the noise comes back. Looks like what comcast installed should allow the MOCA2 bands to operate as you experience.
