Not looking great, up powers are very high, but it needs VM to take a look.
Try calling it in as a fault (on 150 VM line - or 0345 454 1111 others) and see what they say when they test your connection - the call centre is still picking up and calling at 08.00 (Mon-Sat) or 09.00 (Sun) gives the best chance of getting through quickly.
Also, in the meantime... if you haven’t already, set up a free and secure “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” to the “share live graph” option (as per instructions on the TB website) when it starts to develop.
