Cox and MoCA share the same coax line.
Cox and MoCA share the same coax line.
Based on the different MoCA versions and hardware setups, compatibility can vary. This depends on devices adhering to the same configuration and channel settings to prevent signal interference.
MoCA 2 was created to work with DOCSIS 3 and 3.1 standards. The initial version supported DOCSIS 2 but faced challenges with DOCSIS 3. Additionally, it’s recommended to place a MoCA filter at the point where coaxial cable from the coaxial provider enters your home.
The main goal was to repurpose the unused coax lines after removing the old network. Adding a MoCA filter at the ground connection should suffice. A second filter at the modem connection is advisable for added protection.
You’re good with Cox internet alone. Adding Cox TV won’t cause problems since DECA adapters are designed for satellite, not cable channels. For MoCA filters, install one near the cable entry point to prevent your signals from leaking into neighboring homes. If multiple residences or apartments use MoCA without filters, their networks will combine and share bandwidth.
You can easily mess with the area by just taking out the filter. Thanks.
Just in case you're aware: if enough individuals express concerns, they'll employ signal analyzers to pinpoint the source of interference—even if it means a thorough, step-by-step inspection of each node. It could be time-consuming, but by then the local staff and supervisors will likely be quite frustrated because the process dragged on.
Edit: To clarify, since you're using DECA adapters that operate on standard cable channel frequencies, the splitters and amplifiers should prevent signals from traveling upstream. Cable splitters typically have multiple inputs and outputs, besides simply dividing the signal; most are equipped with passive components to stop feedback. The need for separate MoCA filters arises because higher frequencies can evade these filters. Even with your DECA adapters, it's still wise to add a MoCA filter for added protection.
It seems like the signal issues are quite significant. Cable Co has reported that interference is impacting their network. There have been cases where the company had to physically remove a customer's cable to resolve the problem before determining the source of the disruption.
Updated: The attempt didn't succeed. The DECA adapters caused interference with the internet connection going to the modem. I experienced a significant decrease in speed after linking the DECA adapter to the splitter on the modem side. At that time, nothing else was connected. Initially, everything worked fine—just the splitter between the wall coax and the modem. Once I connected the DECA adapter to the other coax port on the splitter, my speed dropped from around 198 Mbps to about 48 Mbps. It's unclear if MOCA adapters would behave differently, but it might be simpler to run a second coax line from the cable box outside to the room with the router. You should be able to do this easily. All the necessary connections are in place; just need to route the cable from the attic down a suitable path as shown in some videos. Thanks for your support. Final advice: keep the internet line separate from the MOCA/DECA line, using different coax runs.
