![]() That setting isn't available from the customer GUI, so a call to Comcast would be necessary to make certain that it is set, but the Gateways are typically set up as PNC by default, so this shouldn't be necessary. If you have any issues, the one thing I didn't mention is making sure the Gateway is set up as the PNC (Primary Network Controller). Port to Port Isolation (when it travels from one output port to another) = 25dBĪnd if you have a MoCA filter, that reflects the signal, so it is about -2dB to the total. Before moving on, you must have a cable Internet connection in order to use MoCA adapters. Splitter loss (when it passes between an input and out on the same splitter) = 5-8dB 3 steps to enable MoCA on a Xfinity router. Total attenuation cannot exceed 72dB, but preferable to keep it under 50dB.Ĭable loss = about 7dB per 100' of cable it has to travel between devices Then, if you want to make sure things work, do the math: See if you have a MoCA filter at the ground block, but chances are you do (it's rare to find a house without one anymore). You just need to make sure the coaxial outlets you are using are all connected, using quality components (no gold Radio Shack splitters or 40 year old crimped connectors). They are rated to carry video at full 4K for Wireless Xi5 boxes, so they offer "satisfactory throughput". That's a non-issue for a while, especially since attenuation of those high frequencies would require re-engineering the entire system to account for loss.Īll Xfinity XFi Gateways (basically, anything less than ten years old) run MoCA 1.1 or 2.0. Yes, the 3.1 standard allows spectrum up to 1700 MHz to be used, and DOCSIS 4.0 ESD can go to 1794 MHz, but that will require major plant upgrades throughout the system that are expensive and will take years to accomplish. What about those DOCSIS signals above 1002 MHz? Nobody is even using them yet. That keeps your MoCA devices from trying to talk to the neighbor's devices, plus the filter acts as a reflector, increasing the signal strength across the MoCA network by 2dB. To illustrate the point, the Comcast X1 system with the XiD client boxes is COMPLETELY MoCA-based, and has been installed millions of times with our standard "1002 MHz Splitters", with sometimes a dozen devices on the network.ĭo you need to worry about the Point of Entry (POE) filter? Well, you are supposed to have one if you have MoCA, but once again, if Comcast has been there in the last 8 years, then there will either be a MoCA filter at the ground block/tap, or it will have a ground block with an integrated MoCA filter. It just changes the attenuation, so we plug that number into the math to calculate MoCA signal strength. They don't need to be "1500 MHz", because 1002 MHz splitters pass the signal along just fine. if Comcast has been there in the past decade or so, then what you have will work fine. That's why we create industry standards in the first place, such as DOCSIS, USB, and IEEE 802.11.ĭo you need to worry about the splitter? Not really. That being the case, anything labelled as "MoCA #" has to be compliant and compatible with anything else with that same standard, so YES, your extenders will work. MoCA stands for Multimedia Over Coaxial Alliance, of which MoCA is an agreed-upon industry standard for communication over coaxial networks. Just buy from a reputable retailer with a good return policy so you can test them with the wiring in your home, as not all home wiring works well with Powerline AV adapters.I see so much misinformation here, I'm just going to simplify this to accurate answers that address your actual question. Powerline AV adapters is another great way to get an ethernet outlet in a room where one doesn't exist yet. Same goes for these off brand ones you linked to. In the world of networking, you get what you pay for (usually) so even cheaper name brand extenders can introduce more interference than the range they extend causing worse wireless performance than if you didn't have them at all. Yes, my first thought is invest in a system that actually works well, such as a MESH networking system, or at least a Ubiquiti Access Point. so extending wifi, or getting a repeater with shorter cable so its closer to my room would be the best option i think. Parents said i cant drill a hole, or add an access point to the wall in my room so i can have a direct cable. the router is in the room directly above me, and winds around the house and what not. I use the 5Ghz, while the rest of my family uses the 2.4Ghz (their laptops dont support 5Ghz, and the apple TV only sees the 2.4Ghz)īut im not sure if any of these would be compatible with the router.Īnd i can put a cable to my room because it would be about 35-40 feet of cord to my room. So i have this Router - With Comcast internetĪnd i was wondering if there would be a way to extend the range so i have a better connection from across the house with a wifi extender or repeater.
