Continuous brief loss of interent/wifi the last few months

Continuous brief loss of interent/wifi ...

Connection problems that affect both Internet and TV service 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 or http://10.0.0.1):

• model number
• uptime
• downstream: power levels, SNR (or MER), and error counts for all channels
• upstream: power levels for all channels
• complete 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.)

Copy and pasted text is preferred over images. Be aware that, if you post any images, your message will be made Private for a time, as all images must be approved by the Forum Moderators before the messages containing them become generally visible.

You would likely be charged for a tech visit if bad coax, splitters, amplifiers, or connections are found in your home (even if Comcast originally supplied them) 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.

We are in Plymouth, MI and started having these same issues Friday/Saturday.  I can't tell if its the router or external.  Things clear up for a while after restarting the router, but then return later in the day.  Its sporadic.  There have been no physical changes to our home, router, cabling, etc.  It normally just works.  It's in a temperature controlled room so is not environmentally overheating or dirty.

During the last disruption a short time ago I ran Ping Plotter v5 and it shows heavy packet loss across all hops when pointing it at any of the pre-defined destinations (Google was one).

I conclude that this is a problem outside of the home.

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 someone else's thread can delay getting help.

@BruceW  Thanks for your feedback.  I will try to track down all the information to share, but do you think it would be a coax issue if neighbors on my block with Xfinity are also experiencing the same issues?  I just heard from a neighbor a few doors down and they have been dealing with the same sporadic loss of service, specifically the internet.  I don't have the Service Protection Plan and I don't mind calling a tech, but I think it's ridiculous that even if Xfinity installed something faulty I would end up being liable for paying for that service.

There's just no way to know without someone onsite to check out the problems. Suggest you send the DM that @XfinityJoe requested and take it from there.

Please circle back here and post any possible solutions for the issue here in these open forums so that all readers here may benefit from the exchange / info. This is in keeping with the spirit for which these public help forums were originally intended. Thank you.

I’m in Minneapolis, work from home, depend on reliable internet, pay for higher tier, and feel like I could have written this. Unfortunately here outages are often much longer - 30 min to several hours of no internet whatsoever. I too sign up for text updates each time there’s an outage and receive none. According to outage map the cause is Network Damage. How long until it’s fixed for good? Is there a way to sign up for text updates that actually works as advertised?
