My upload speed cuts out randomly

For about a month or two (I forget exactly when it started) My upload speed has been cutting out (down to 0.08) for about 20 seconds. It happens at least once an hour. 

My download speeds are fine and unaffected when this happens. 

I know its not the following:

  • hardware issue (this happens on every device, all drivers are updated)
  • modem/router issue: Has been replaced 3 times and I've used different cables every time.
  • modem/router location: this only started after Xfinity did a long scheduled outage for maintenance. I also have tried multiple outlets and both coaxial outlets after this problem started.

I have no clue what could be causing this.

I've the same problem. At random times speed drops to 1 to 10 Mbps. Another slow down started happening on a Sunday at 1pm.  If I'm on a video conf call, it is a pain. Basically roll of a dice if speed gets laggy.

This is certainly not the experience that we want you to have with your connection,@user_8f32e4. What type of Modem or Gateway configuration are you using, and what are your normal speeds? Is it the Upload or download speeds that are having the issue? Are you connected to any type of VPN (Virtual Private Network) when this happens?

This is also happening to me. It's been going on for a little over a week. I can no longer livestream without it causing the stream to drop. I haven't received any assistance or read up on any solutions to this. Please let me know if there's any help you can provide.

I am following this because this sounds similar to mine. I got a text saying they were doing work in late September. Ever since then I've had stream drops and frequent t3 timeouts on modem log. Replaced everything, techs replaced what they can etc.

If you get a solution plz post it here. I will do the same. Out of curiosity do you happen to be in northern Illinois as well?

+1 to the above. Randomly cuts out multiple times during video calls. Incoming audio is fine but my mic becomes garbled or cuts out entirely. Exact same thing happens on my wife's calls as well at the same time.

Equipment replaced, multiple technician visits, and no improvement.

Hi @danb0934! Sorry to hear you're also having this issue! 

 

Have you by chance been able to check the event logs for your device? If so, does anything look out of the ordinary? You can also post them here, just please make sure to remove any private/identifying information like the MAC address.
