Superhub5 rebooting

Up to speed

My Hub5 has been rebooting recently but tonight it was because of a "Cable Modem Reboot because of - kernel-panic". It had rebooted at 3:00 am but that was due to a software update. A kernel panic sounds a tad more serious. Anyone had anything similar?



Do any of these apply to your system :

1) RTSP stream / VRChat crashes & reboots Hub 5.
2) Sonos via Wi-Fi may be a trigger of Hub 5 reboots.

Unfortunately neither apply in my case. BTW I mostly use Linux and I only stream video from Amazon fire devices on my TVs and the apps I use are Netflix, Amazon Prime and YouTube.

The Hub5 rebooted again at 21:46:01 because "Cable Modem Reboot because of - kernel-panic". I was watching YouTube on my TV using an Amazon Fire TV Cube.

Hi Callinder, 

Thanks for using the Community Forums to get this issue with your broadband looked into, I am sorry if this has been causing some frustration 😥 I would be more than happy to look into this for you! 

I have taken a look at your services already and can see that your Hub has not been rebooted in nearly two months, this might be what is causing your connection issues as the Hub needs to be rebooted every once in a while in order to reset the data. 

If you could give your Hub a quick reboot for me and come back to me tomorrow, I will recheck your specs. 

If my diagnostics are still showing an issue then we will look into it closer ad get an engineer sent out 👨‍🔧

Sounds odd, not seen a kernel panic on a Hub before. I do know VM recommend a weekly Hub reboot, again strange.  I usually only reboot my Draytek for firmware updates, so uptime of months is not uncommon.  The only other Hub 5 log mention is “RG reboot” on the Forums.

I suspect that VM’s recommendation to reboot the hub is probably down to the inadequate firmware. When run in modem mode the hubs are much less stressed and probably less memory problems, I rarely reboot mine.

There are 10 types of people: those who understand binary and those who don't and F people out of 10 who do not understand hexadecimal c1a2a285948293859940d9a49385a2

And your conclusion about the hub in modem mode being far less stressed would seem perfectly reasonable and hence needing fewer (if any reboots).

What I do find odd are two things, firstly Megan’s post just above in which she says that the hub hasn’t been rebooted in two months is in direct conflict with the OP’s contention that the hub rebooted less than a week ago at 3am, and has been rebooting from time to time due to a kernel panic.

So something isn’t right here, either whatever diagnostics VM ‘s forum team are using, simply aren’t reporting the truth, or what the OP is reporting as a ‘reboot’, isn’t!

Secondly, of course, the idea that the hub ‘needs to be restarted every once in a while to ‘reset the data(?)’’, is, of course a nonsense, unless, as you speculate, the VM firmware, isn’t really very good.

Sorry for the delay in replying but I've been away for a few days. Anyway when I arrived back at home my Internet connection was playing up again. I did a hard reboot which took an age to complete but before doing this I checked the router and on the home page this was shown for the Internet status, Internet(Partial Service (US only)). I have no idea what this means. Now everything appears to be OK but this is happening too often.

US is upstream, ie data you are sending out to the internet. You should have four (possibly 5 depending on ‘stuff’) upstream channels which carry your data. Partial Service means that one or more of these channels is/are not working properly, probably due to noise (interference) on these channels.

However, no real need to panic, the underlaying technology is designed to be fairly robust and do what it can to keep you online regardless. 

If your connection seems to be OK, then, honestly don’t sweat it, otherwise you will drive yourself nuts obsessing over log entries.
