Yes. While I was trying out some Moca devices, just to see how MoCA worked, the Cisco TAs were completely rendered flaky by the MoCA. It's not a matter of the Cisco TAs just not being able to pass the MoCA through the internal amp and whatnot, they just can't handle MoCA signals. They should have been designed with a built-in MoCA filter, but either were not, or it's just not working. I thought you were "in the know on this"... Cox doesn't include MoCA filters with the self-install kits, as a "just in case", or by "assuming MoCA is present in the coax". They know about this situation, and went from withholding PoE filters, to giving them out just to make sure this doesn't happen. When you compare the TiVo instructions and diagrams to the Cox provided ones, TiVo would have you "pass-through", while Cox wants that split and PoE filter. Since I didn't stay with MoCA, I just placed one filter at the actual Point-of-Entry, to cover the whole house from outside ingress, and put the rest in my "box-of-cable stuff" box. People do need to be aware that a neighbor with MoCA and no PoE filter can punch their signal into other houses (egress & ingress), whether they use MoCA, or not. If a PoE filter is not at the PoE, a non-MoCA house can get poltergeists in their Tuning Adapters. Using Cox's split w/PoE at each TA would at least cover the Tuning Adapters. Obviously, a single PoE in a non-MoCA home is the better approach, while the split w/PoE is pretty much a necessity if MoCA is in use. No idea on the Motorola TAs. I've never had one, or known anybody who did. It seems they are less prone to this, based on the things I don't see being reported with them in MoCA situations. Many devices can be subject to MoCA-induced malfunctions. Cable modems, TV tuners, and more. Most new devices that have coax-in, now have built-in MoCA filters, like newer cable modems (that are not MoCA bridges), or any device that isn't design to be part of a MoCA network. Unfortunately, some that have them built-in, don't do the job, or fail. If it's not cost prohibitive, some might be best-off to place filters strategically, to only allow MoCA to get where it needs to go, and nowhere else.
