New to EE from BT, Zoom constantly freezes

[Piper1862]

I recently moved from BT (with them many many years), EE plan Essentials Full Fibre Gigabit. 
I am using the EE Smart Plus Hub and 3 Smart Wifi plus boosters.  Speed into the house is around 900mbps and upload 100mbps.

Everything is great apart from when I use zoom.   It constantly freezes, document slow to load and sharing a video eg YouTube is impossible.   All of this worked perfectly when I was with BT.   

When I first signed up I got one wifi booster, Zoom poor,  they then sent another (I asked for 2 more) but  advised not to have 3 as .if they are too close it can cause a problem'.    Zoom still not working properly.  Engineer booked.  Engineer said this is a know problem with Zoom and Teams and advised a TP Link PowerLine adaptor.. call EE and they will send one.   Called EE  wouldnt send a TP Linc until I had tried a 3rd wifi booster.   Booster ordered and he said 'you can have 3 boosters no problem', totally contradicting the previous advisor!!
3rd booster connected Zoom still not working.  Called EE yet again,  SAID his team leader (or similar)  will order a TP Linc as he didn't have the option to send one, it will take up to 72 hrs.   As expected 72hrs came and went nothing received.    Another call to EE and told I cant have a TP Link I have to hardwire!!   By this time I was fuming...  I bought a TP link and Zoom still not working.  Computer hardwired to router. guess what.. zoom still not working. 

And of course I am way outside my cancellation period so stuck with EE rubbish for 2 years.  
Looking on this forum there are a couple of other posts regarding a similar situation but they were last year.   Am I the only one struggling? 
Any suggestions please.

Thank you for your response.   I wasn't too sure, if there was an issue with zoom I would expect a lot more posts in this forum.

It's an odd one for sure.

i feel your pain.  Forced to leave BT and tied to EE for 2years!

@Piper1862 Did you have any joy from the reply on your original post?

[Piper1862]

No.   Still having problems.   When in a zoom meeting I ask members to let me know in the chat when I freeze.. Today 1st half of meeting constant freezing 2nd half ok although throughout I has several unstable internet messages.. I did a test on Saturday and hard wired to the router, 5' away, and still had freezing. 
No idea how to resolve this.

@Piper1862 Did you read my reply or just skip over it?

[Piper1862]

Happens all the time now we are on EE.

Exactly the same issue here but only weeks into my new contract. Just had the router replaced but guess what….no better than the previous one. Was your issue ever resolved? 

[PPPP2]

Yes, turning off parental controls enabled zoom, you tube and other video services to function normally.

[StevieC22]

Have double checked and parental controls are off.

Issue only arises when both wife and I are working from home, her on Teams and me in Zoom. At this time both our devices display ‘unstable WiFi’ warnings and we’re told by clients that we appear pixelated, videos lag/stutter and comms generally become very poor. Feels like a bandwidth issue to me but was never an issue with the previous BT router.

Welcome to the Community @StevieC22.

Was it the BT Smart Hub 2 you were using previously?
If you still have this, can you give it a test to see if the same issues occur when using that?
