Just a comment... if I were doing online classes, or important Zoom or Team meetings etc - there is no way I would do them on a wifi connection - it is far too flaky for that. I always connect my laptop to my router on an ethernet cable and get a rock solid connection - wheras my wif connections go down when we switch our new Panasonic Microwave oven on !! It just the way of wifi!
So to do an experiment to see where the issue lays, can you determine if your issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables? If you don't know, can you check on one to help diagnose whether it is just a wifi issue or it could actually be network connection/Hub related?
If it is a wifi only issue then see this...
To address the wifi issues, VM now supply “wifi Pods” (no longer doing cheap and cheerless and poor value “boosters”). However, their Pods are only free to customers on the 1GB, Volt (or old Ultimate Oomph) packages - is that you? If so they are worth trying - they should work for you. VM Wifi is now “guaranteed” to 30 Mbps/room it’s now called… Wifi Max
See if anything in here helps….

You call 0800 064 3850 to order the first one after scanning for blackspots using the connect App.- or just wait here for a VM person to respond in a day or two and they will sort the first one for you. If you do call dont get fobbed off by the offshore CS agents' saying you aren’t eligible - if you are - it is clearly stated on the webpage.
If not free to you… you will be charged £8/month for up to 3 pods (note - BT charge £10/mo for their whole home wifi solution). It’s a simple solution and should work for you. However, you would soon pay off that cost by buying your own wireless solution that will be yours to own and use forever, although the VM Pods should be a simpler option.
If you do want to invest in better equipment, you would need to get either a… (1) Mesh System, (2) Wireless router, (3) Wireless access point(s), (4) a pair of good quality Wifi Powerline Adaptors, or a combination of (2&3).
£40-100 (that’s ~4->12 months of Max Pod rental) should sort it for most customers with an average property and usage. Spend more for additional advanced“features” - if required.
