Advertisements Conventional wisdom says to put a moca filter at the point of entry. Which was my set-up for close to two years. In the last two weeks, I kept losing internet. Nothing changed in my home. But Spectrum also said no outages, nothing unusual in my neighborhood. They sent a tech out and immediately he was uncomfortable seeing my moca adapters, he was also uncomfortable seeing a moca filter. I just think when you're not sure what's going on, those are easy things to target and blame because those are things they did not install. He didn't really have any definitive answers for me what's going on. He did have his gadgets that communicated back and forth with Spectrum. He would test out the line by connecting to his gadget, and not the modem. I wonder if this testing process was actually the cure. In any case, after his visit. My internet is rock solid, I have not lost connection for close to 24 hrs now. He did several things, which he admitted were minor, and that we still need to monitor things. But I am perplexed why after close to two years, these things would be issues. 1. He grounded a wire at the p.o.e. He said it was never grounded. But why after close to two years, this would be an issue now? 2. He put a 2-way splitter before a 3-way splitter. The modem gets a connection on this 2-way splitter, and the other line goes to the 3 way splitter. But again, from Fios to Spectrum, and back and forth, all the installers have always used a 4-way splitter. Why is this an issue now? 3. He took off the moca filter. And again, why is this an issue now? 4. He took away the moca adapter at the modem, so the cable goes directly to the modem 5. He disabled WMM APSD on both wifi frequencies. When he left, I put back the moca adapter at the modem. My logic is if I can't use my moca adapters, then I'm leaving Spectrum anyway. So I don't need to know or care to know if the internet works perfectly connected directly to the modem. So this has to work my way, or not at all. So anyway, with the moca adapters in play, I'm still getting rock solid internet. Prior to the tech visit. It would drop completely after every 30 minutes or so. I had to unplug the modem, and disconnect coaxial at the p.o.e. Then reconnect everything. I haven't had to tinker for close to 24 hrs now. So #4 is not the culprit. But I also can't see why 1,2, or 3 are the culprits either. #5 is interesting, could that function cripple a network? I'm also thinking when he was testing the coaxial line by plugging it into his device, could that process actually somehow magically put everything back in order? Metaphorically, was that the actual CPR? I wanna put back the moca filter, but I'm worried that it is actually the culprit and I might mess things up and require the tech to come out and do CPR on the lines again. LOL! What do you guys think? And going back to my headline, how vital is a moca filter? Maybe I can live with people stealing internet connection or some channels, but can they get into passwords and stuff just because I don't have a filter?
