Modem rebooting multiple times per day plus packet loss (Hub 3)

Had some occasional packet loss during peak times but today the Hub 3 appears to be rebooting at random times.

Can't access the Hub during these times.

Aware of the heat at the moment, but ventilation around modem is good and other network kit is working without any issues.

Hub 3 is in modem only mode.

Not sure if my forum account is linked to my VM account.

Can't see the edit button on mobile, but just had another outage around 23:12.

Re: Modem rebooting multiple times per day plus packet loss (Hub 3)

Power and SNR levels look fine - VM will need to do some digging around to see what is going on!

Post up your actual network log (far right tab in the hub stats)

Also, set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at ThinkBroadband (https://www.thinkbroadband.com/broadband/monitoring/quality)
Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum!

Re: Modem rebooting multiple times per day plus packet loss (Hub 3)

Forgot about the graph, looks like my IP changed so it's missing data from yesterday. 

https://www.thinkbroadband.com/broadband/monitoring/quality/share/d46eab3279255ea299fa0a1d0868d07a9f...

Managed to catch it going down, all lights seem to flash red then seems to go through a boot cycle (edgerouter gets the 192.168.100.1 address then gets the external IP).

Logs are below (doesn't look like much):

Re: Modem rebooting multiple times per day plus packet loss (Hub 3)

Confirmed its definitely the hub restarting, doubled checked the lights on a boot by pulling the power and it's exactly the same, seems to be increasing in frequency as well.

Re: Modem rebooting multiple times per day plus packet loss (Hub 3)

Hi @Makakar,

 

Welcome to our Community Forums and thanks for posting. 

 

I am sorry to hear you are having problems with the service. I have located your account and everything looks good this end. 

 

Can I ask you to factory reset the hub and let us know if you notice any improvements thereafter?

 

Thanks
