Recurring T3 timeout

Hi there,

I have a recurring T3 timeout that noticeably impacts how my internet operates after it occurs (certain things will not load or take an extended amount of time to do so etc.)

I have had technicians out in the past who say I am at the end of the line in my apartment complex meaning it could be numerous things at any of the other boxes for other buildings that is triggering it. I subscribe to Gigabit Pro and do get my advertised speeds. I have a customer owned modem/router (Netgear CM3000, and Asus BE96U Wifi 7) which I have replaced the CM3000 after my internet has been having issues. The last time I had a tech out he rudely and ignorantly told me "I don't care what your equipment shows, I am here to look at the line and that's it."

I then explained my equipment is simply showing that something on the line is wrong at a certain point of the day and it conveys itself by showing a T3 timeout as well as some uncorrectable error codes on certain channels. He then doubled down and said "I don't care about your equipment or how good it is, I am going off my tools, that's it."

Basically I have had numerous techs come to this place over the last 7 years and only once a Comcast rep that sees over the PNW market actually ordered a node split because we were "over subscribed." As a long time Xfinity customer I feel absolutely helpless and defeated at this point. None of the techs want to do the work that clearly needs to be done in this instance which is taking the time to sort out where this issue is actually stemming from. Instead it is dismiss the customer, do the bare minimum when it comes to a tech visit and bank on someone else eventually living here that won't notice there's a problem because they only stream Netflix.

Signal levels are all within spec:

FTD Hello and thank you for reaching out to Xfinity via our Xfinity Community Forums. I'm sorry to hear that you're experiencing recurring T3 timeouts and that it's impacting your internet service. I understand how frustrating it can be to have internet connectivity issues, especially when you pay for Gigabit Pro speeds. I appreciate you taking the time to detail the situation and the troubleshooting steps you've already taken, including having technicians come out and replacing your own equipment. I can't comment on the specific interactions you've had with technicians in the past, but our goal is always to provide excellent customer service and ensure our customers have a positive experience. I also understand your point about wanting to get to the root cause of the issue.

 

 

I see from the information you've provided that your signal levels appear to be within specifications. However, the T3 timeouts in your modem's logs do indicate that there may be an intermittent issue on the line. Can you tell me a little more about how often these T3 timeouts are occurring? Is there a specific time of day or activity that seems to trigger them? The additional details may help us narrow down the potential causes.

 

In the meantime, I'd like to do some further troubleshooting on my end. Could you send a Direct Message with your full name, the name listed on the account (if different), and the service address associated with your account to get started? 

 

To send a "Direct Message" message:

Click "Sign In" if necessary

Click the "Direct Messaging" icon at the top of the page (looks like a text bubble)

Click the "New message" (pencil and paper) icon

Type "Xfinity Support" in the "To:" line and select "Xfinity Support" from the drop-down list that appears. The "Xfinity Support" graphic replaces the "To:" line

Type your message in the text area near the bottom of the window

Press Enter to send it

It seems to be reoccurring at 01:09 AM pretty regularly but other times at random times. I had a tech scheduled to come out but cancelled as it seemed okay at first. It is now not okay again. I will post my log and signal levels below:

@FTD Thank you for providing that valuable information. I understand you had cancelled a technician visit and then the connection issues began again. I'd like to perform some additional troubleshooting and get a closer look at the signals on our end. Please send us a DM to Xfinity Support with your full name and address to get started.

To send a direct message:
Click "Sign In" if necessary
Click the "Direct Message" icon or  https://forums.xfinity.com/direct-messaging
Click the "New message" (pen and paper) icon
The "To:" line prompts you to "Type the name of a person". Instead, type "Xfinity Support" there.
As you are typing a drop-down list appears. Select "Xfinity Support" from that list.
A "Xfinity Support" graphic replaces the "To:" line.
Type your message in the text area near the bottom of the window   
Press Enter to send it
