Have you checked for “known network faults”?
As well as trying the “check service,” Area status webpage" (link at top right of this forum), also try the “free & automated” Service Status number - 0800 561 0061 - which usually tells you of more local issues down to postcode level. These may not be listed on the Area Status web page (Areas are not “Geographic” they are billing areas) as that usually only covers faults affecting 1000’s of customers) so phone may give you more info, but even that may not cover problems affecting a few customers.
If nothing shows on there, try calling it in as a fault (on 150 VM line - or 0345 454 1111 others) and see what they say when they look at your connection. The UK 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.
You can also text them on 07533 051809 include account name/number and what the issue is – replies usually take longer.

To get some evidence, 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” (as per instructions on the TB website) when it starts to develop.
