Hi,
Just an update on this, I had an engineer out who looked at the cabinet and ran some diagnostics on the Hub 3 but couldn't find any problems
He did suggest that I might need a new modem as mine is quite old now.. the internet has still been dropping randomly each day but today it's been really bad (1st drop)
See below for the BQM, the internet dropped and the modem reset just after 2pm - so as suggested I switched the hub back in router mode and removed my own router.. then factory reset the hub (2nd drop)
The internet was up for about 10mins then dropped again, and took around 35mins to reconnected.. flashing green and then red (3rd drop)
Then it dropped a 4th time after packet loss (and it's just dropped again right now as I'm typing)

Anyone has any ideas on what's going on here? The fact this is 10 times worse in router mode than it was in modem mode maybe suggests the hub needs replacing? See logs if that helps:

I've also seen this error too, the logs seem to reset when the modem reboots itself
Thanks,
