Superhub4 Repeated Rebooting?

[roakes]

Hi,

We have a Superhub 4 and regularly throughout the day I see the white light start to flash like it's rebooting, however when doing so our internet does seem to stay up. I have an external Wifi router attached to the Superhub serving the house, so maybe it's just the Wifi functions rebooting which we're not using so don't lose connection?

However, there have been some periods where the connection around the house does drop and we go offline for a minute or two, so I think some reboots are more severe than others.

Is there anything I can check in the router logs to identify an issue or can someone from Virgin diagnose remotely?

Thanks

Please post some stats.

How to get stats from a VM hub (no need to logon to the hub)

Open a web browser and go to 192.168.0.1 router mode or 192.168.100.1 modem mode

• Click on the “> Check router status” button
• Click on the “Downstream” tab, copy the text and paste into your reply, do not take a screen shot
• Click on the “Upstream” tab, copy the text and paste into your reply
• Click on the “Networking” tab, copy the text and paste into your reply.
• Do NOT post photos or screen shots they will be rejected as they contain MAC addresses. The board software will automatically change MAC addresses to **:** if done as above.

I logged into the hub to check the network info there and it thankfully had timestamps.

The temporary outages coincide with the event "US profile assignment change. US Chan ID: 14; Previous Profile: 12; New Profile: .;"

Hi @roakes,

Thank you for your posts and welcome back to our community forums. We're here to help.

I'm very sorry to hear that you're experiencing some intermittent connection loss recently. I've checked over things on our systems and I'm unable to detect any faults currently. How are things for you today? Any better?

Thanks,

[roakes]

Still got issues I'm afraid, I set up a BQM:

https://www.thinkbroadband.com/broadband/monitoring/quality/share/829fa271672f778b879e8397cbfcca99de...

However, I also used the online service check tool which did detect an issue and I now have an engineer scheduled for Wednesday morning.

Hi @roakes 

Thanks for coming back to the thread.

I am sorry it's not sorted but glad you have an engineer visit. Please let us know how the visit goes.
