Microsoft Teams regularly freezes - tried everything...

for the past year, my Microsoft Teams connections has been freezing for a few secs on a regular basis.  This tends to happen every 15-30 mins when I have video on, but not when the connection is audio only.   

Sometimes I get an error message in Teams "your connection is poor", sometimes the call will actually drop for a few secs before resuming, and sometimes the sound and image will just freeze but no message will show.

Our IT team have reviewed the Teams logs and have escalated it to Microsoft support, and they are both of the view it is my internet connection

I am running W10 latest release and also the latest version of Teams.  There's anti-virus and endpoint protection software  (FortiClient) but everyone else within our company has the same set-up and they don't have the same issue with Teams.

I have 350mbps down / 35 mbps up, and usually get good speeds s. 

I am using my Virgin Hub 3 in modem mode with an EdgeRouter X doing the routing.   Using the Hub in router mode does not fix the problem

My flat is wired up with Ethernet cabling, and I have tried extensively with both wired and wireless connections - but the issue is the same on both.  For Wifi, I use the  BT WholeHome mesh system (normal, not the Premium one)

below you can see my broadband monitor for today.  nothing out of the ordinary I think but I am no expert

below are my Hub status logs.

I would be grateful if any of the resident experts on this forum could give me a point of view on whether I may have a Virgin connection problem?  and/or whether you can think of anything else that may be causing this

Re: Microsoft Teams regularly freezes - tried everything...

some of your downstream power levels are (i believe) a little on the low side and one of your four upstream channels is only negotiating a QAM of 32 - it should be 64.

Not sure that the above would result in intermittent issues with teams, though it might. 

you're already configured in the recommended setup (modem mode, decent router, cabled connections) so unlikely to be an issue there.. 

the hub3 does have known issues with udp traffic (which a lot of teams will be) and whilst this has been improved over the years with patching, it's a fundamental hardware issue, so impossible to completely eliminate.. that said, plenty of people successfully use the hub3 for teams calls..

your BQM shows consistent packet loss at all times of day, so there's obviously /something/ that's not quite right.. 

can't offer much more help I'm afraid - your best bet is probably to get VM to agree that there's an issue with power levels etc. and send you an engineer to try to rectify it... i'd probably hang tight at the forums rather than calling in, the forum staff seem a little more willing to get engineers out to investigate than the call centre.. that said, it can take them a few days to respond to posts..

Re: Microsoft Teams regularly freezes - tried everything...

Hi @ROBR296

 

Thank you so much for your post and welcome to our Community Forum! We're very happy to have you here though I am very sorry to see you have been suffering with intermittent connections.

 

I have had a look on your account and I can see there  are some long standing performance issues. For this reason I have booked you out an engineer to come and look at the equipment. 

 

You can view this appointment by logging into you My Virgin Media App or by logging in to your account online here. You can also reschedule the appointment should the allocated time not work for you.

Re: Microsoft Teams regularly freezes - tried everything...

hi Ashleigh

thanks for arranging the engineer visit.  Unfortunately the slot that has been booked does not work for me.  I went online to re-arrange the visit, but it does not show in my account.  Would you be able to re-arrange it for some time next week instead of this Friday?   or make it visible online so that I can rebook it myself?

thanks in advance!

Robbie

Re: Microsoft Teams regularly freezes - tried everything...ls

pls disregard my earlier message about rescheduling the engineer's visit for next week.  i just got a text message from Virgin saying they are bringing forward the appointment from Fri this week to tomorrow, which works well for me.  all good.  thanks again for your help.

Re: Microsoft Teams regularly freezes - tried everything...

VM engineer came to the house today.  He replaced the forward path attenuator and the Superhub 3 with new ones.  He said that should hopefully fix the issue.  Everything back up and running now, but need to have some video calls to see if the intermittent performance issue is now gone.  Will report back.

Re: Microsoft Teams regularly freezes - tried everything...

unfortunately the engineer's visit does not appear to have fixed the issue.

when I am doing MS Teams calls, the connection will still drop occasionally and the call will hang.   so exactly the same behavior as before.  

When I run a continuous ping trace ("ping teams.microsoft.com -t") to the Teams server at Microsoft, I can see that the ping is timing out for a couple of pings while the connection drops.  it never lasts long, but long enough for the connection to drop or freeze during that time

my sense is there is a problem upstream from my premises

Re: Microsoft Teams regularly freezes - tried everything...

Hi ROBR296

 

Thanks for coming back to us. All the levels are in spec so no issues showing. 

 

Can you pop the hub out of modem mode for me so we can run further checks?

 

Kind regards,
