I don't know if this relates to your problem, but if you are subscribing to Xfinity TV channels and use a rented wired cable box at the TV, you don't even need to have in-home Internet or WIFI to watch TV. The TV channels and some apps are delivered to the TV through the COAX cable. Some people think that they need the Xfinity Internet service to watch TV. If you are using a wireless Xfinity box, you do need Internet service, and you still need the box to decode the Xfinity TV channels that you pay for.

I doubt it. I don't even have channel 157 on Xfinity.

We live just north of 466 and get momentary loss of signal occasionally with Xfinity. Now it is just for short periods - like 15 or 20 seconds. About a year ago it was much worse and they came out and installed a new cable from the house to the terminal box in the back yard.

If you notice it is worse after a rain it is likely the cable buried in your yard; like it was for us.

Great, thanks! I think this is the problem. We had a lightning storm and I think it hit very close by.

We had this exact problem a few years ago, lightning strike so close we heard it, felt if and saw it at the same instant. The neighbor had around $7000 in electrical damage, we apparently had none, UNTIL around 18 months later, the cable for the Comcast signals started to fail. It took 2 technicians and a few hours to figure this out, and a week later we had a new cable, and no problems.

No issues like that up in the Sumter Landing area. We are using a 7-year-old Arris modem. Xfinity speed is 1Gb but usually runs about 400 to 500Gb

We had the same issues for several years ( live south of 44 in new area). It would get very frustrating. Finally we switched to Spectrum and never had the issue again. Sometimes I thought that Xfinity may not have sufficient infrastructure and it gets overwhelmed. There was never any explanation for it but a lot of people complain about.

I’m in DeLuna and our village definitely had some hits during that last wicked storm. A home was hit and burned, and our veranda neighborhood had a street sign hit at one of the entrances that caused it to fall, and then the water main at that corner was also hit which caused a loss of water pressure, and for some homes water was lost completely for several hours. Thankfully our Spectrum internet wasn’t affected. It was a wild night!

We blip from time to time. More than any place I’ve lived in the past 20+ years. I power cycle the router/modem combo to speed up the recovery. It comes right back. Alexa devices take a bit to realize it’s back up, too, so I power cycle the one I need to use.

I had Xfinity come out to the house multiple times with new modems that did not correct the problem you are talking about. They said one of my cable outlets had interference and I had someone come out to replace the wiring to that outlet. I was lucky enough to have a neighbor that had a family member who had worked for Xfinity tell me to go buy your own router and modem. Problem solved. Apparently Xfinity can mess with their own router/modem without you ever knowing, and messing with your internet. I would imagine it has something to do with amount of traffic they have.

I would be skeptical that this information is accurate. Xfinity provides the Internet service, and they can "mess" with it if they want to, regardless of who owns the modem. It is not your Internet, it is their's.

Do you know the speed rating of your 7-year old modem? Your modem may be creating a bottleneck, which will cause your Internet speed to be slower than what you are paying for.

From Hitrontech.com:

"Age of the Modem: If your modem is more than five years old, it’s likely outdated. Technology has advanced considerably in that time, and your modem may no longer support current internet speeds or security features."

If it happens a lot, bring your router to the Xfinity store and get a new one. They don't last very long, and everything is refurbished.

I agree. I rent my router from Xfinity for two reasons. One, they will replace it anytime you want. And two, if you have an issue with your Internet service, they can't blame it on your router.
