New Hub reboots at midnight every night

Hi folks.

So i previously had the Superhub 2.0 (had it for about 7 years) and i encountered an issue where the wifi networks would randomly vanish  maybe once a day (even though connection via ethernet is fine) and i would have to restart the Hub to get the wifi networks to show again. I rang VM and explained the issue and the person i spoke to changed some settings apparently and asked me to see if the issue persists. 3-4 days went by and I had the same issue so I rang back and a new Superhub 3.0 was sent out. I connected this up and everything is ok with the wifi now.

However now the Hub reboots at nearly dead on midnight every night now and ive never had this issue before! I've rang up today and I have an engineer coming out in 2 weeks but to be honest i dont have any faith that this is a hardware or connection issue as my broadband is rock solid speed wise and doesnt drop out at all so im convinced this is a setting somewhere thats causing the midnight reboots.

Re: New Hub reboots at midnight every night

VM "may" be doing some routine "updates/upgrades" at that time that is causing it.

However your down channels are showing more than usual PostRS errors that isnt healthy, they may just be "historic though. So, try rebooting the Hub to get them reset to 0 and then check back in to check that they have - and then monitor them over the next day or so. They shouldnt reappear - if the do it will need a VM tech to take a look.

Also, in the meantime to get a record of the midnight dances - set up a free “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts - 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.
If you just see a wall of "red" then your Hub is not accepting the "pings" - make sure you uncheck the “ignore ping from WAN side” box in the settings - note it will take an hour or two to start seeing a sensible picture.

Re: New Hub reboots at midnight every night

You hub is not rebooting every night. What it happening is it is losing connection with the VM CMTS at the other end of your cable. It then go into a loop trying to regain the connection and it eventually succeeds. So don’t think the Pre & Post RS error will reset every night, they will not. The only way to reset them is to power cycle your hub.

Re: New Hub reboots at midnight every night

Went down again 12:20 - 12:45 No connection at all and couldnt even interact with the router via http://192.168.0.1 as it refused to even take me to the login page or acknowledge the router was there

Re: New Hub reboots at midnight every night

I presume you are testing the connection and logging on to the Hub3 from a cable connected devices. The only other explanation, other than VM maintenance, is perhaps someone on your street box is doing “something funny” on the internet at that time, although I think this is very remote.

Re: New Hub reboots at midnight every night

I am connecting via Ethernet and it seems this issue has only started since i changed the Hub from the 2.0 to 3.0 and it wouldnt expect that VM have been doing maintainance 4 days in a row just after midnight. I never had this issue with the 2.0 Hub, other than recently the wifi disappearing (but not the connection via ethernet) which is why i asked for a new Hub.

Call it rational or not im convinced that the first person who I spoke to, before i got the new Hub, "changed some settings" in their own words which I believe is causing the issues
