We just had Fiber Optic cable installed in out community 1500 homes. Since then, a lot of the homes get freeze picture, and pixelation frequently. We also get WIFI on same cable ... and drop the connection for ten or fifteen minutes at a time before it re-connects. The set-up it WIFI TV as well as internet. So we lose everything.Not one or two, but probably all or most homes. Comcast says it's US, our house cable or our TV or our equipment (Their equipment) and mostly will do very little. Occasionaly, will dend out a tech and tell us everything is working properly. IT's NOT ...We are a senior community, and lots of folks online or on TV and much of the day. This install is recently complete - several months.I suspect Comcast installed a lower grade or small size Fiber Optic cable, and it's over-loaded. Any comment from you tech experts?? thxBTW: All boxes in our homes are new, and installed at the same time.

Hard to say, but fiber was the best, fastest internet I've ever had. Sure sounds like a faulty installation.

If it's every home, it's bad installation. Keep calling Comcast. Every time it happens. Also call the city or county or whoever has the contract with Comcast.If that is the only option you have for TV and internet the problem won't fix itself.

Has anyone made frequent speed tests with a reputable tool such as Ookla in order to determine if slow or overloaded Internet is the problem or something else ....

I just ran a speed test now ... 111 mbps DL --- 9 mbps ULSo, not the cable, but I don't know how many people are on it now at 4PM ...Our community has the contract ... but our BoD does pretty much nothing, most are worthless - as usual - some try, but are in a minority until next election.Comcast does the same thing each time it comes out ... and says nothing wrong. But something is wrong because we keep getting signal loss and pixelation, and we lose the internet. All is intermittent - no set schedule for it to fail. One minute we're watching a baseball game, next minute, nothing but a Rainbow screen. Five minutes later, it re-connects. Pixelation is random - minute or so at a time.I'm ready to confront the BoD, but need at least some tech info besides "it fails". BoD signed a community contract, so we have it in our HOA fees ... pay no matter if it works or not. Comcast knows that, keep deferring when one person calls ... it needs representation of our community.I Know, I know - HOA, as usual, mostly worthless - but it is what it is and we live here when not on the road.

“ Comcast says it's US,…”Just you or you and many of your neighbors? If it is a bunch of you…get after them. Does Massachusetts regulate them? Start with your local elected officials.

Does it happen at say 2 or 3 in the morning? That will tell you if it a overload situation. Could be a bad CAU or LAM if they are still used. Insufficient transmitting power, dirty/poor connections trying to do too much with too little.
