Multiple Outages Every Day

We have been having outages every day, multiple times a day for the past month or so. Starting around 9AM til 9PM. Loss of signal on the modem. Usually lasts anywhere from 2 minutes to 3 hours. I have called multiple times, once I was told there was some work and they have constantly "closed my tech visit" for me because of this. Some have tried to blame the modem (which is mine) but this only happens during the day time hours. Its completely stable after 9PM or so.

What work is being done, and when can we expect to have a reasonably stable Internet connection again?

Central Florida; 34715

I've begun monitoring, and below is just a week. Its also testing every 5 minutes so its not catching the tiny blips.

... Loss of signal on the modem. ...

Are you connecting via Wifi or Ethernet? If Wifi, it's best to switch to an Ethernet cable connection if possible for testing. That would allow you to determine whether the problem is the Wifi signal or the link between your modem or gateway and Comcast's network. Network connection problems that affect both Ethernet and Wifi devices are often due to poor coax connections or damaged coax cable, usually in or near your home. Running the cable through a surge protector, a defective splitter, or too many splitters can cause signal problems as well. If there is an amplifier in the line make sure it's getting power. 

If you want to troubleshoot this yourself, please see Internet Troubleshooting Tips. If you still need help, please post your Internet plan speed and the following information from your modem or gateway (from http://192.168.100.1):

  • model number
  • downstream: power levels, SNR (or MER), error counts, and uptime
  • upstream: power levels
  • event log, if available (Be sure to remove or blot out any MAC addresses. Forum security processing considers them "personal information" and may prevent the event log from posting if these are present.)

If you can't find the problem or you'd rather have Comcast take care of it and an employee does not respond to your message here, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. It's not likely they can fix the problem remotely. If not, insist they send a tech out to identify the cause and correct it.

If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit ($70-$100) unless you have their Service Protection Plan ( https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device or anything outside your home you shouldn't be charged.

Please be aware that there are 2 kinds of responses in this Forum: Replies and Comments. When you Comment on a post by scrolling down to "Comment on this post here...", I am notified of your response. But if you select Reply, I am NOT notified and may not be aware of your response.

Hello, @User_85960. Thank you for voicing your concerns here on the Xfinity Forums. No one likes a service interruption inducing me. I know it's frustrating to lose connection. If one or more of your Xfinty services are not working you can check for a reported service interruption in a few different ways. The Xfinity Status Center is a quick and easy resource to check your account status, and, if nothing is reported you can even fix common issues.

In some instances, we can determine your interruption status. If you've registered your mobile phone number for Comcast Alerts, you'll receive proactive text messages for certain service-impacting interruption types providing that information. You'll also receive estimated resolution timeframes, periodic updates, and a final message when the services are restored.

Additionally, you can text OUT to 266278 (COMCST) to check for interruptions in your area. Data and messaging rates may apply. You can also choose the option to Text me with updates to receive a text message update as soon as your Xfinity services are restored. I hope this info helps!

Sadly no, its still constantly up and down. It's been online and working since the 8th but that was over the weekend. I fully expect it to drop again at least twice today and going into the week.

I'm going to call again and try to get a tech to visit and just test the lines, or at least tell us there is work in the area.

Same thing here, 08021 last two weeks or so, few times a day Internet goes off for few minutes. Any ideas why is it happening and when it is going to be fixed?

Also on Xfinity website it was a note for a while that outages were reported and it will be addressed couple days ago. Obiously it did NOT get addressed

Hi, @user_3c34a2! Thank you for patiently waiting for a response after contacting XFINITY over our forums' page for help with the internet service concerns. I have been in your shoes before so I can understand the inconvenience that this can cause. Are the services still going off for a few moments since we last spoke?

@user_g9rvd6 

Please create a new topic of your own here on this board detailing your issue. Thanks. 


For future reference, it is better to submit your own post as it creates a ticket to get help, and posting on an old thread can delay getting help.
