My wife is facing an issue whereby she very regularly has a "your internet is unstable" notification on Zoom, and also very poor quality on Google Meet. The download/ upload/ ping look fine - so now I wonder re. the router itself (Hub 3) or the bandwidth. She is using a Mac.
Any advice would be much appreciated.
It's unlikely to be the Hub, and it certainly is NOT a bandwidth (speed) problem. Difficulty with videocall types of service are almost always due to latency or packet loss problems, and those are caused by power level or noise faults on the incoming broadband connection. The majority are an easy fix in one visit for the field technicians, a few are more difficult, and a very few VM never resolve.
I'm assuming you've carefully unplugged the coax cable between hub and wall, and made sure that it's securely refixed with any securing nuts firmly finger tightened? And restarted the hub for good measure? Subject to that, wait for forum staff to pick this up and hopefully book you a technician - if you phone in as a fault there's a good chance you'll end up trying to explain the problem to clueless idiots who are insisting everything is working fine and that it's some fault with your wifi, or that you need to upgrade your speed.

Or alternatively, they’ll try to sell you some WiFi Pods (a snip at only £8 a month extra guv, and absolutely guaranteed to fix your problems - hint, they won’t ever, ever fix your issues!
The thing that kills time-sensitive connections like Zoom etc. is a phenomena called ‘jitter’ which is the unpredictable, random variation in latency. And this is something that VM’s underlaying network infrastructure is somewhat prone to, simply as a by-product of the way it works.
So here’s the best advice, probably not something that you want to hear but still, can you investigate another supplier which uses the BT/Openreach cables? The speed will be a lot slower, but the latency and jitter is usually a lot better. Could you stomach paying for two connections, a ‘fast’ one when you simply, want to download games etc. and a ‘slower’ but more stable one for Zoom/Teams meetings etc?
