A few questions to try and get to the bottom of it. How long has it been going on? VM often schedules work on the network/updates etc in the early hours that can cause this. However, it doesn't usually continue for weeks.
Also is your connection a wfi one or on ethernet cable connected gaming devices? If its wifi it could be some external interference (outwith your control) due to some device (e.g. in your house - or your neighbours) "switching on" at the same time of night.
Do you know whether other (non-gaming) devices in other rooms of the property also drop out at the same time? Both wifi and ethernet connected ones?
To get some evidence to show to VM, if you haven’t already, set up a free “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” (as per instructions on the TB website) when you have the first 24h period.
