I'm having a chronic issue with my work's VPN Global Protect but only while on my home network. Internet is generally pretty good around the house but my work laptop that uses GlobalProtect drops every 10-15 minutes, whether I am on Wifi or ethernet. It seems to be the upload that is most affected as sometimes I will freeze and lose audio on a video call but still be able to watch and hear teammates asking if i'm still there It all works without issue on other networks so there's obviously some conflict with my home Virgin Media setup. I have tried turning off for 15 minutes, performed a hard reset etc all the classics to no avail.

Mystery solved... it was actually another device on the network that was playing up. I reset it and all is well

Members of the forum frequently report call quality issues with MS Teams.
Other conference call platforms see very few reported issues.

Please share the details from the Upstream and Downstream tabs,
these figures give us an insight into the quality of your connection to the VM Network.

  Teams is definitely an issue but I have other connections that are disrupted like DB queries which take longer than 3 minutes to return results

    Lets see the 2 tables of data for the downstream channels
    Also, If you haven’t already, set up a free, secure and “offlsite” - “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph”. Click the lower link (Share Live Graph) then, click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see. On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK

Thanks for responding. I've only just rebooted the hub so this may not be so helpful. There are generally T3 timeouts

The Upstream and Downstream power levels look at least as good as ours and we don;t have Teams dropouts or glitches when streaming TV.

Note the BQM should be configured to point to the Public PIv4 of the VM Hub,
it should not be configured to point to the IP of the office VPN's exit point.

The 3 red sections imply there was no response during those hours,
was it the case that you suffered a total loss of internet during those hours ?

If not what is this BQM graph actually reporting ?
Because the red paint suggests BQM is pinging at a device that is not always powered on.

  it's weird isn't it. the internet is working ok right now yet it's showing as 100% dropped packets. perhaps i've set up the monitor incorrectly, it's set up using the ipv4 address

    to be clear, when i say the internet is working ok, i mean it appears to be fine for all devices other than my work laptop via the VPN. while i'm not 100% sure i would detect intermittent dropouts so much due to a different usage pattern on other devices i have used my phone on the wifi for teams calls with success
