I have the exact same problem as you and i'm struggling to work from home and missing multiple meetings. VM really need to investigate as I spend hours waiting on the phone to escalate. They need to acknowledge this is a wider issue as multiple users are impacted. Also have you managed to test the hub in router mode to see if the issue still occurs?
Appears to be a pretty common issue. If it weren't for some of the great people on the forum spending their spare time sifting through our stats to help people for free then it would be far worse.
Yes I have tried almost every combination of configuration I could think of. Nothing helps as its clearly an issue on their side which they cannot workout how to fix. I will be up to my 5th engineers visit to fix the same problem on Thurday.
I've just got of the phone from the VM tech team who have advised that it might be worth lowering my speed to see if my connection stabilises. i will let you know if that help as I'm willing to do anything stop these dropouts so i can get some work done.
