Dropped connection/router reboot nightly

[robatwork]

I have only had my VM  for a couple of weeks.
Each night around the same time I lose connection, and the router reboots itself. 

After 5-10 mins I get a connection again. This seems to happen around midnight.

Previous similar posts have had a request for the router network log with MACs suitably munged:

Anything I can do/check or does it need an engineer on site?

thanks in advance

It rebooted itself again last night so that's now 5 nights in a row, between 12am and 1am it has dropped out. Unless there's something VM are doing to reset the router remotely?

VM often do maintenance overnight. It looks from the logs that the hub if not rebooting, but just losing connection to the VM CMTS. Please supply full stats and we can then get a better picture.

Thanks for the reply! Happy to oblige with more stats - can you let me know where as the Advanced/Tools menu doesn't show anything more comprehensive than the above?

Hi robatwork,

Thanks for your post, and welcome back to our Community Forums.

I'm sorry to hear you're seeing disconnections overnight on your service. I've had a look on our end, and it does look like over the past couple of days, there have been some levels on your service moving out of specification, and some high packet loss.

I'm going to send you a private message, so we can look into getting somebody out to check this. Just like last time, it's up in the top-right, purple envelope.

Thanks,
