Slow broadband Microsoft Teams

[Evzzy]

Hi Having problems with WiFi speeds \PC performance when running MS teams. @broadbandspeeds @ Microsoft teams. Connected via WiFi to router super fast broadband no problems at other times. It's a work PC MS surface (1.5yrs old) and it all started about 3 months ago I noticed that when on a teams call \ screen share the PC fan comes on and the pc becomes unresponsive, browser pages take ages to refresh, flicking between tabs on the browser really slow. It typically takes 5 mins for the problem to manifest and then once I come off the call the performance improves again. It's impossible to work now on teams effectively. Been onto IT at work (big corporate) checked PC all good, it works fine in the office on the WiFi there. Narrowed it down to an issue with the sky broadband. Had a new router sent (same as old one but hoped for new software\firmware). Didn't fix it, tried ethernet connection -no improvement. Other devices connected simultaneously run fine when I'm on a teams call on my main device. Even running a another work pc along side off teams it performance is fine accessing the same account documents where as the one on teams struggles. Swapping the pcs\ set up it's always the pc that's running teams that is slow. It may coincide with work updating all our devices with a security software called iboss. It used to work fine, work said it may be a conflict between that and the router. Tried an extender - no improvement. Can any one help....?? Really frustrating have no idea where to go next, sky technical said all they can do is send another router which we've done. An option is to change provider as I can't function in my job.

Its nothing to do with Sky broadband, you've already described the problem, Teams, in combination with whatever the security software is thats installed, is obviously taxing the CPU of your surface PC quite hard so after a few mins it becomes overheated and the fans spin up and the CPU throttles your performance to stay cool. 

You also said other devices on your Sky WiFi perform fine on teams at the same time so you need to go back to your company's IT support as its their problem to fix, not Sky's.

I have exactly the same problem with my work laptop with Teams when screen sharing. It's a Teams issue because it's very heavy on GPU use when sharing screens etc.

Teams can be heavy on gpu.

But, would try the following;

This involves, disable GPU hardware acceleration
Open Microsoft Teams. Click on your profile photo and click on Settings
Under application select Disable GPU hardware acceleration. This requires restarting teams and a Windows restart.
On launching Microsoft Teams after this change, click on the close button in the
Microsoft Teams. It will not kill the process, but will minimise it to your taskbar.
Open Microsoft Teams and see if your if the problem still occurs.

One other Teams cure, is around disabling read receipts.

Its more a cache clean.

In Teams, click on your profile picture and select Settings.
Select Privacy. Look for the the 'read receipts' option
Disable Read Receipts, save changes.

Thanks. 

That's what I thought but what I couldn't understand was the fact that I didn't get the problem when in the office connected to the corporate WiFi?  This is what's directed work IT to me and my home set up. 

Don't think it's my PC set up as the one I borrowed from work\same spec did the same thing. 

Previously tried the GPU setting and cache clear (thanks for suggestions guys). Didn't help. 

Really don't know where to go from here? 

Thanks

An update following further testing (can ayone offer any other suggestions?):

PC works ok at home when not running Teams  calls. After starting the teams call after 4-5mins PC fan comes on, PC gets hot [near touch pad] and everything slows down - can't navigate through browser tabs (Chrome) access files via office 365/sharepoint, teams itself is very slow to respond to actions (mute/ screen share etc).  The call video and sound is OK (gets more laggy as the call time goes on). After stopping the Teams call the PC then takes about 5mins to cool down and performance gradually improves. 

Tried Ethernet connection - no improvement 

PC works fine when I go to our main offices and run on the office Wi Fi -- no issues on performance (infact its quicker and more responsive despite it being on a large office WiFi which has a stretched band width). 

Added my Security Software (iboss) addresses to the Sheild 'allowed web sites' as sky suggested. Made no difference. 

Tried connecting to a Wi Fi extender and running off this (to fool the router into thinking I'm not directly connected to it - Tech Guy at work suggested this??). No difference!

Tried it on someone's Talk Talk Broadband over the weekend and no problems!! 

It looks like its Sky broadband is the issue. 

Cant get to speak to Sky Support at the right Technical level which is frustrating! 

Any thoughts? Switch Providers - is becoming more of a realistic option at the moment -- but not ideal.
