Hub 3 appears to keep dropping connection/ rebooting

[kerrygold]

I'm having intermittent connectivity on my hub 3 and this has been happening randomly over the past 4 days. I've had a VM engineer out this morning who checked all the cabling in the house and in the street and replaced the existing hub 3 with a new one however this hasn't fixed anything. I've also phoned twice today after experiencing the issue and phone support cant see an issue with the hub or the line but there definitely is a problem.

My setup is currently all hard wired (no wifi) and the hub3 is in modem mode but I can see the issue occurs on the hub3 and not the router as it appears to reboot when the issue happens. I setup a broadband quality monitor this morning after seeing the issue  here https://www.thinkbroadband.com/broadband/monitoring/quality/share/dec972b457d5ca9237d4a335b152c9b903....

While running multiple ping tests, what ive noticed is the hub becomes inaccessible before the internet does and then after roughly 30 seconds the hub comes back to life but the internet will not return for ~3 minutes.

The most recent occurrence of this actually left something in the network log unlike the past several occurences:

Try a full factory reset on the Hub as below.  Once done you will need to put the Hub back into modem mode before you re-connect your Router.

Remove any ethernet cables from the Hub and hold the pinhole reset switch for 60 seconds. Do NOT reboot the Hub, just let it do it's thing. Note you will need the passwords from the bottom of the Hub afterwards, so make sure they are legible.

I have just done exactly what you recommenced so hopefully I see some better results but time will tell.
