It looks like the hub is struggling to communicate with VM servers, possibly a noisy line.
You could check the coax cable from the hub to the cable entry point for obvious signs of damage and all connectors are hand tight.
Otherwise, you will need to contact VM for resolution, either by waiting here about a week until a VM Forum Team Member picks up the thread, or give them a call on 150 from a VM line or 0345 454 1111 for a quicker response.
Sorry to hear about the disconnections you're having. I've taken a look at your Hub and I can see a few time-outs, however it's showing that you've been online for 11 days without a reboot. Would you please perform a full reboot (remove power cable for 30 seconds) and post back when you've done so. This will clear the time-out counters so when we check again we will know how many occur on a daily basis.
Thanks for your patience,
