Hi,Ive received a hub 5 due to my previous hub 4 failing. It has been working well but for some reason it keeps rebooting between 2-3am every Tuesday morning. So far its happened twice in the last 2 weeks. I have called CS multiple times but I just get the usual rubbish (reboot, reset etc). I did a factory reset on Tuesday midday but then for some reason the hub rebooted on Wednesday morning at 2:40am. CS say its maintenance or firmware updates but I have a BQM running on my neighbours VM line and that doesn't go down so it cannot be maintenance. As for firmware updates, the version stays the same. Hub 5 is in modem mode. When the reboots happen, I get "cable modem reboot due to RG reboot command". Something isnt right as I never had these issues with my hub 4. The only thing that stands out is my upstream modulation keep fluctuating between 64qam and 16qam but CS say they cant see any issues with my power levels. Anyone had any similar issues? Not sure what to do next.

There is a problem with your US, as you know they should all be QAM 64. A VM tech will need to sort that out.As for the RG Reboot, I've no idea. However, coincidently, my Hub 5 has done this as well quite recently and I use modem mode. I'll be keeping an eye on that one for sure.

This is the issue, the CS team dont seem to have a clue so they dont want to send out an engineer. Then theres the issue with some engineers, they cant see any issues. So I just keep going round in circles. The RG reboots could be due to the noise in the upstream? Not sure. Would be interesting to know if other hub 5 modem mode users experience the same rebooting issues.

went through a long period of this and I never found out what the resolution was. I had to have an engineer come out and tell me there was nothing wrong with my connection to then raise it with networks as the forum team cannot do this. The following week no reboots at all. I never found out why. However, this morning I had a reboot at 2am I hope this is not starting again as it disrupts all my security cameras and my NAS who start messaging me to tell me the network is out at 2am!!!! good luck but you really could do with a compitant engineer to attend to sort this out.

If you find nothing wrong I be disappointed even with the dam thing in router mode😞

Hub 5 Rebooting Every Week

Hi,

Ive received a hub 5 due to my previous hub 4 failing. It has been working well but for some reason it keeps rebooting between 2-3am every Tuesday morning. So far its happened twice in the last 2 weeks.

I have called CS multiple times but I just get the usual rubbish (reboot, reset etc). I did a factory reset on Tuesday midday but then for some reason the hub rebooted on Wednesday morning at 2:40am. CS say its maintenance or firmware updates but I have a BQM running on my neighbours VM line and that doesn't go down so it cannot be maintenance. As for firmware updates, the version stays the same.

Hub 5 is in modem mode. When the reboots happen, I get "cable modem reboot due to RG reboot command".

Something isnt right as I never had these issues with my hub 4. The only thing that stands out is my upstream modulation keep fluctuating between 64qam and 16qam but CS say they cant see any issues with my power levels. Anyone had any similar issues? Not sure what to do next.

Thanks

There is a problem with your US, as you know they should all be QAM 64. A VM tech will need to sort that out.
As for the RG Reboot, I've no idea. However, coincidently, my Hub 5 has done this as well quite recently and I use modem mode. I'll be keeping an eye on that one for sure.

  This is the issue, the CS team dont seem to have a clue so they dont want to send out an engineer. Then theres the issue with some engineers, they cant see any issues. So I just keep going round in circles.
  The RG reboots could be due to the noise in the upstream? Not sure. Would be interesting to know if other hub 5 modem mode users experience the same rebooting issues.

    Hi avi68,
    
    Thanks for taking the time to post on the forums.
    
    I'm sorry to hear you've been having some issues with your Hub 5. I've had a look on this side and whilst I can't see any issues on the surface, we can't see everything due to the Hub being in modem mode.
    
    Can you please take your Hub out of modem mode for us and pop it in router mode? Once you have, let us know and we can take another look.
    
    Thanks,

Looking at your DS & US, they indicate the HFC Amplifiers in your area are incorrectly aligned in the Upstream.

With +5-6dBmV downstream, I would expect US to be lower than 46. The impact also depends on which drop-tap you are connected to in the cabinet.

Would be interesting to see the signal levels for your neighbour's modem.

  Another hub was posted to me 2 weeks ago but the rebooting issue is still occurring. After multiple phone calls I have finally managed to get an engineer booked to visit. We know it isnt the hub as this is the third hub 5 I have received. I have also started to get packet loss and drop outs. When looking at the logs I can see "16 consecutive T3 timeouts while trying to range on upstream channel 8". Again customer services cant see any issues. Hopefully I get an engineer who can fix this.

  Hi avi68
  Did you ever get this resolved? Experiencing the same issue, new Hub 5 went in 10 days ago on Service Activation and been having reboots between 2am-3am every Tuesday, Wednesday and Thursday night since.
  Router is configured in modem mode and it was switched out same day as the previous user who had a Hub 5 in modem mode on the same cabling for 18 months without issue.
  
  Just wondering how they managed to resolve your issue as looks to be similar

    Sorry Faceman09 I've just seen your message.
    So after complaining multiple times it magically fixed itself. I have a feeling someone from the networks team changed something their end which stopped the reboot issue occurring.
    I had not changed anything my side, the same hub 5, it's still in modem mode, same cables, same router. The issue started itself and then fixed itself. The only advice I can give is to submit a complaint and hope to get it sorted that way.

Long story short, old account has been closed (returned old hub 5), signed up as a new customer and received a new hub 5. Since connecting the new hub 5 I'm starting to get reboots early in the morning again. The first week I had reboots on Tuesday and Thursday morning between 2-3am. I then did a factory pin hole reset. This week (second week) I had a reboot today (Tuesday) at 2:40am.

CS have no idea whats happening. Last time I think the networks team fixed it because it magically started to behave. Please can you escalate this to the networks team.

  Hi avi68
  
  Thanks for posting and welcome back to the community. Sorry to hear of any Broadband issues. We've not been able to run full tests when attempting to do a diagnostic - is your Router in Modem Mode? If so, can you kindly pop it in Router Mode and let us know?
  
  Best wishes.

    Hi John, could you tell me what additional tests are required in router mode compared to modem mode? I've already done this when I phoned up the CS agent last week. Their "diagnostic test" didn't show any issues.

went through a long period of this and I never found out what the resolution was. I had to have an engineer come out and tell me there was nothing wrong with my connection to then raise it with networks as the forum team cannot do this. The following week no reboots at all. I never found out why. However, this morning I had a reboot at 2am I hope this is not starting again as it disrupts all my security cameras and my NAS who start messaging me to tell me the network is out at 2am!!!! good luck but you really could do with a compitant engineer to attend to sort this out.

  I also had the same issue with my old hub 5, I had at least 3 engineer visits where they said they couldn't see anything wrong. I had the hub changed at least 3 times, again no change. Then by magic, it stopped rebooting.
  It seems the process is to get an engineer in to escalate it to networks as (like you said) the forum team cannot raise the issue directly and neither can the complaints team.
  I know how you feel, I have some backups running over the internet at night and these keep getting interrupted.
  I have raised this to ISPreview as it isnt just me whos having these issues.
