Internet disconnects same exact minute, most every hour, last 2+ weeks

Still happening, I've tried

-a couple hard resets on gateway modem/router (all in one device)

-setting a static ip address, no change so back to default

-checking ip lease times, they are a week apart. (ip lease times were left out when using a static ip, is that due to it not changing?

-traceroute and ping tests that show up normal when connected to internet

Every xfinity person I've spoken to has a different story: there's an outage that will be fixed the same day, another told me that I was only connecting to two towers and I should be connecting to 6 (I know nothing about this at the moment, is that sound advice?). Yesterday I was told to not call back till a tech comes, and a tech can't come out for over 10 days because of the risk with co-vid but my neighbor had a xfinity truck over their house 2 days ago. I don't mind to wait due to crisis, but I hate paying premium prices just to be lied to and possibly being told BS, I am not a fan of this.

Anyone gone through this and have some ideas?

Well over a month dealing with this happening every day, and comcast won't do anything to help since "it is not disconnected at the moment when talking to them on the phone." They refuse to send a replacement modem or send a tech out to try and help, even when xfinity told to us they were, and when we call back they know nothing about it, and will do nothing further.

I think the best thing to do, is if you have other internet options other than xfinity in your area go with them!!! We are going to look into AT&T, T-Mobile, and others if anyone has some recommendations.

I have the same issue that my wifi disconnects exactly every hour for about 1 min. It turns out that it is not a problem with the modem, but a problem with the network adapter driver in my Windows 10 computer. Just try "roll back driver" or "update driver" (search online how to do it specifically). For me it solved the issue

Hope this helps

I have had the same issue for the last two weeks.  Internet goes out for 2 to 4 minutes at 42 or 48 after the hour randomly.

We will be moving to another provider soon since this isn't being resolved.

I have the same problem. Just connected to Comcast. Called to a customer representative and he told me that was because I wasn't registered. So I registered, but the problem persists. 

Every 30 mins or so my modem goes off. The lighst aren't on. I need to reboot the modem and it works. Then again goes of.

So I have been dealing with this same exact issue now for 2 weeks - I was having terrible overall internet experience with Xfinity in my area (Connection drops/ping spikes were bad using high end equipment) I have my own Arris SB8200 Modem and a Netgear Nighthawk X6 Router.   I also have a high end Netgear Managed Switch in place to hardwire my TV and Gaming Devices.

My Switch will email me everytime it goes offline and also keeps logs - Recently due to lack of acceptable service and lack of interest in spending an hour or 2 on the phone I let the bill lapse a bit until I felt like calling to get my issues resolved - XFINITY placed me on their XAP 50Mbps assistance (COVID) plan and honestly it was sufficient enough to still stream my Youtube TV etc so I didn't bother to deal with it... After about a month on the XAP this issue started happening going offline for 1-3 minutes in EXACT time increments.  

I started keeping logs of the Auto emails from my Managed Switch and noticed that one day it would go offline at 31 & 01 every half hour - The next day it was 04 on the hour every hour - Following day 29 & 59 every half hour.

Each day was a different start time, but once the first outage happened the following cutouts would be in EXACT to the minute 30 or 60 minute increments.   

So I figured this was some kind of tool XFINITY was using to get me to call and pay my past due bill and get off the XAP plan - I paid the balance, called in and cut my services to the minimum levels and cleared up the account.

Now this issue is still ongoing even on my "200Mbps" connection  -  EXACT to the minute increments.


This cannot be a hardware or wiring issue on my end - That is impossible to cause incremental outages if those are the circumstances (I am an IT Field Engineer)  - This has to be some kind of controller on XFINITY side that is timing out our connections with some kind of failed handshake.


Would love some input from Xfinity Engineer on this - Where can I turn to....Maybe I should report to local media my logs and findings (as this actually seems intentional in some way)

In the meantime I am likely going to move my wireless and home internet over to Verizon Fios as I cannot have my work from home system going offline during meetings and calls like this.
