unstable/unsuable internet: frequent pocket loss leading to network errors and stalls

Thank you for reaching out to us @user_souips! Our team can most definitely take a further look! I appreciate you for confirming this is happening on wireless and hardwired connections.

Are you noticing these intermittent issues on multiple devices at the same time or on one particular device? Are you using a VPN?

Thanks XfinityAldrik for responding. This issue is happenning on all the devices. For all activities such as browsing, streaming. It happens whether you VPN or not. I tried both VPN and not VPN. It is not just one device. All the devices in household are facing same issue.

Also zoom calls, the call just freezes for 10 to 30 seconds. Then resumes. Since I work remotely this issue is severely affecting me. As I posted above screenshot (in original starting post) during red bars the internet freezes on all devices. Please help me in resolving this. Thanks.

Thank you for confirming both VPN and non-VPN connections are impacted on multiple devices @user_souips. You mentioned we had installed a new modem when you moved to the new home, have you sent any signals to the modem on your end using our Xfinity app?

If you haven’t, I highly recommend sending a few signals to the modem using our amazing Xfinity app.

XfinityAldrik, Yes I have sent signals to restart using xfinity app from my phone. I also restarted the modem numerous times. The restart of modem doesn't help at all.

At this time, I’d like to take a deeper look at the signals going to the modem @user_souips. Could you please send our team a direct message with your full name and full address? To send a "Direct Message" to Xfinity Support:

Click "Sign In" if necessary
Click the "Direct Messaging" icon or  https://forums.xfinity.com/direct-messaging
Click the "New message" (pencil 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
 - An "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.

1. Xfinity technician visited and changed filter in xfinity junction box on the wall outside house. Also replaced exiting modem with new modem. This didn't solve the issue. I showed the issue (youtube freezing up etc) to the technician. He said will report back.

2. Later in direct chat/message, one of the reply I got was xfinity is aware of some issue in local node and maintenance staff will address it. After that one fine day the problem went away and my service is error free.

Notes: To figure out this issue pingplotter is a great tool.

Thanks: I would like to thank Xfinity "direct message" staff for being patient and following up with me at regular intervals until problem is resolved.
