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.
I have Virgin for years, I recently moved property and decided to upgrade from 350Mb to 500Mb.
Never had an issue with my 350Mb link, since moving and getting a 500Mb link I have been plagued with the midnight (usually 12:37am) restart of my router ("hub").
This has been going on for over a month (shortly after the line was activated [didn't happen initially]).
The hub is in modem mode (as the previous one [returned] was at the old address).
The hub is connected to my Tri-Band Linksys Velop Mesh WiFi system (as it previously was), not using anything other than a single LAN port on the hub.
It's not the mesh WiFi system (I haven't even plugged in my PiHole), the hub reboots, complete system restart/reboot cycle (off > white > green > magenta).
My "gaming" device is my desktop but that's irrelevant, as soon as the line drops all devices lose connectivity (for 5-10 minutes while the hub boots), be it watching Netflix, browsing, etc.
I saw a previous post that mentioned the “Broadband Quality Monitor”, I have signed up but will have to setup my Linksys system (tomorrow) to permit the ICMP request (as it will get ignored/swallowed).
Usually it’s because they’re performing maintenance. There’s nothing really you can do about it.
