Have you tried an ethernet cable connected device ?
VM Hubs are renowned for their poor Wi-Fi, and at the best of times Wi-Fi is a fickle beast that can be affected by numerous things such as distance from the Hub, building construction, other electronic devices, neighbouring Wi-Fi, basically all sorts.
VM supply to the Hub, after the Hub it is up to you.
Many on here, myself included advocate the use of a third party Gigabit capable Wi-Fi router or Mesh system.
I think it may be a large number of 'Pre RS' (Errors on the line that need correcting) and 'Post RS' (Errors on the line that couldn't be corrected) Errors on some of the channels which point to an issue.
I'll give it a go thanks, I need to buy a dongle to connect a cable to my laptop, but it sounds sensible. It's pretty terrible though re: Wifi, I can literally be sitting directly in front of it when these issues occur, is it really that bad?
Reboot again (switch it off for 10 mins) and then look in to check the errors have all reset to 0
