Can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you can post the link straight away.
Post a link to your BQM on here.
Instructions for posting BQM Link
Under your BQM graph are two links in red.
Click the lower link (Share Live Graph) then click generate.
Copy the text in the Direct Link box, beware, there may be more text than you can see.
On here click the Link icon (2 links chain to the left of the camera icon)
In the URL box paste the link you copied and then click OK - you can post the link straight away.
All those counted errors and network log messages are caused by the hub losing communication with VM's local network gear, and that's almost certainly because your upstream power levels are too low. Other than the drop outs, your BQM looks very good. Let the technician fix the power levels, and it should all be resolved. A bit more explanation here in a reply I made earlier to somebody with a related issue.
