VPN connectivity with Xfinity continually dropping!

I have had xfinity for several years and am using a gig speed connection. But lately (in the last 6 months or so), my company's vpn connection keeps dropping.  It doesn't matter whether I am wired or wireless, I continue to have the same issues.  Some days, it is even worse wired than wireless.  I have checked repeatedly with our IT and they have said that the vpn is working fine, and that the issue must be with my provider.  There appears to be no rhyme or reason to when the connection will drop or how it can be reconnected.  I might go hours without an issue, only to have it drop and not be able to reconnect for hours, even though my connection to the home network is still showing connected.  Here is what I have tried so far.....  Need to get this fixed asap as it is essential to my job.

  • I have checked and rechecked all connections
  • I have rebooted both the computer and router often - no effect
  • I have disabled Advanced Security
  • I have tried working using Bridge mode.
  • I have connecting directly to the router with no other connections.
  • I have tried removing and reinstalling the VPN application (Global Protect).
  • Someone in a similar forum post mentioned checking signal levels and I looked at ‎Internet Troubleshooting Tips | Xfinity Community Forum .  I am not technical enough to read it properly, but here is what my router reports:

I have the same issue and my company IT department have done extensive research to try to determine why this keeps happening. Does anyone have the answer?

Having the same problem with xfinity and GlobalProtect dropping connections.  Disabling "advanced security" helped.  Now a connection might be stable for 5 minutes instead of 2.

I take that back.  Still totally unstable.  Reaching tech support has been impossible.

Has anyone been able to solve this? Finding tons of threads in Xfinity forums with this problem as well as Global Protect. I've disabled Advanced Security, there is on or off for this setting which in itself seems odd,  but still seeing dropouts. This is making it impossible to work.

Reaching out directly as every thread on this issue suggests useless. The response is "not our problem" because they are blaming the 3rd party VPN. Which I would normally believe if I had not connected to that same VPN on a non-Xfinity network without issues. I guess it's time to find a new ISP. No troubleshooting, no escalating to an engineer to look at packet captures and see if they can see the issue. Just "contact your companies IT dept".

I had Quantum Fiber installed yesterday and it's been 1 full day on Global Protect VPN without drops. Still monitoring but going to post this in hopes Xfinity Support does the right thing and escalates to a network engineer to investigate packet loss before I cancel my Xfinity internet. 

I worked as an engineer at Comcast for 11 years (not the Xfinity team) and I can say there are great engineers there who can help look into issues and are willing to do so. Unfortunately we can't start the process of troubleshooting if "we" can't admit there is a problem to begin with. 

On Palto Alto boards there are a ton of threads about this issue with suggestions. On Xfinity forums there are a ton of threads on this issue all asking people to direct message Xfinity Support, I suspect to tell people directly it's not Xfinity's problem. This could very well be a VPN configuration but once people state that packet loss is only happening on Xfinity then that deserves to be looked into. Ultimately for me having a reliable connection on my company's VPN is my goal. Xfinity has been unable to provide that and despite the issues only existing on their network, have been unwilling to look into why they are not providing quality service.

@XfinityAlyssaA​ I have to sign in to post here. I have submitted messages to Xfinity Support and received no help. If you can escalate to a network engineer you should know how to get a hold of me. If you want me to message you to get no help again, no thank you.
