Microsoft Teams Quality Issue

Hello all,

I've got an odd issue which I'm hoping someone can offer a steer on.

I have the EE 1.6 Gb Full Fibre Busiest Home package with a Smart Hub Plus.

All seemed to be working fine until my original Smart Hub Plus failed in Jan 2025. This was attributed to a bad firmware update, and a new hub was sent out. I connected this up and again everything appeared to be ok, until colleagues at work started complaining that my video during MS Teams calls was regularly freezing. On my end, I didn't see any issues - I could see and hear everyone else fine so it came as a surprise. Setting up a test meeting that just included me, I recorded myself and when playing back immediately found that the video and audio both freeze and stutter. This is readily reproducible, although sometimes the performance is extremely bad with the video completely frozen. Strangely, this only affects the MS Teams desktop app, with connections via the web browser still being good quality.

So far, everything else seems ok - stable and fast connection (getting around 1.6 Gbps routinely).

Here's what I've tried so far:

  • Updated Teams and all drivers on laptop.
  • Direct cable connection to router with WiFi turned off and all other devices disconnected. No difference.
  • Laptop on WiFi on corporate network - absolutely fine, no surprise.
  • Laptop on WiFi in various coffee shops and on friend's home broadband - all much slower connections than mine and Teams is absolutely fine. Often extremely good.
  • Used phone as 4G hotspot - absolutely fine - extremely good video and audio.
  • Replaced the Smart Hub Plus with an old Asus router I used with a previous ISP - connected to ONT. Connects via PPPoE fine with reasonable speed (around 750 Mbps although using 2.5G port as WAN port, so a little surprised it's not faster).  Connection appears very stable and no obvious issues shown by ThinkBroadband BQM. However, Teams behaves exactly the same as with the EE router - terrible video and audio.
  • Configured Hotspot VPN on Asus router - set location to South England. Connection speed is around 100 Mbps. However, Teams now works absolutely fine. Very good audio and video. Turned off VPN - fast connection restored and Teams video and audio revert to being terrible.

This suggests to me it might be some network infrastructure issue, rather than a problem with the Smart Hub Plus or with the laptop / Teams. Could the route the traffic is following make a difference? If so, how would I go about pinpointing this? The Microsoft 365 connectivity tests don't flag up anything obvious.

After much testing to convince myself there was an issue with the connection I called EE and an engineer visited. He indicated there had been some problems with the Smart Hub Plus on fast connections, tried to run a series of tests but these didn't complete. Reason unclear. However, he was confident that the new Smart Hub Pro would resolve the issues although he wasn't allowed to issue one himself.

Engineer left, job appeared to be closed, then I got a message from OpenReach asking me to arrange a call so that equipment could be delivered. I did, got put through to EE, with the guide saying that I really should have had the Smart Hub Pro already and that he'd get one sent out, although the process for doing this was very difficult. That was almost a couple of weeks ago. Being concerned this wasn't being progressed I got back in touch - over multiple calls now, once I get past the agent telling me I've got a very fast connection and they can't see an issue or find open jobs, when they review previous notes there's a record somewhere to an order being placed, but no-one can find out what. It appears I'm now down as a new customer and something needs to be progressed by the "New IT" team, even though I've been with EE for over a year.

So, perhaps a Smart Hub Pro will be sent out, which will be good because it sounds like I'm entitled to one on my package.

However, I'm not convinced the hub itself is the issue, given that the Asus router performs similarly, except when a VPN is active.

Does anyone have any thoughts about what might be happening?

Thanks!

@Hex93 Which hub do you have? Looking back you would appear to have what is now new named the EE Smart Hub 6 Plus version, if still so then look at the link. From the pinned post below!

EE Hub firmware versions - The EE Community

 

I am not sure to be honest, at the bottom it says 

Smart Hub SH30A

Model number: GRV9518ZWAX34 1-A-SA

 

Not sure if this is smart hub 6

Oh actually I have checked my app and it says smart hub 6 plus

The firmware version is r4.26.3-R-1923144-PROD-8000

As far as I can tell this is not the latest firmware but I don't see any options to update firmware.

@Hex93 If you have the EE Smart Hub 6 Plus version then the latest is below, not sure what you have there. Only EE can do FW updates. Possible what you are posting could be an EE Smart Wireless 6 Plus extender if you have one off those? 

FW: r4.26.3-R-1923144-PROD-83002 and the gui is at App version 3.14.5 12/06/2026 OP Posted

That's bizarre. The number is straight from my EE app which is linked to my smart hub. I don't have a WiFi extender so maybe it's time for me to get in touch with EE in that case? Is it possible this is the reason for the patchy teams calls?

@Hex93 Just switch the EE Hub off for 10 minutes, that will allow a power reset to happen!

@Hex93 It is but it's also one off the very first version's off the EE Smart Hub 6 Plus, so your PROD-80004 may just be correct that way, difference is that it only has a 1GB/s wan port correction which is fine for operation on a FF900 connected ONT.

You will see a couple pictures from the web Manager Interface that shows the FW version differences that the user had so he did compare them. FW confirmed ending at 80004......

Hm have switched it off for 10 mins and back on and it appears that firmware is the same as before.

 

Sorry I think I don't know enough to understand your other comment. Are you saying that there might not be anything that can be done?

Do you have your original router or have you sent it back?

If you still have it, then try it! 

I still believe the EE routers are trying to do something clever with QOS and is totally messing it up.  Switching back to my old router resolved the issue & I've had no problems since.  My problems were evident on Webex, Zoom & Teams.  Looking into the packets & the cause of issues it was definitely hardware related.
