Hub 3 "Rogue Config", cycling every 15 minutes, Broadband down for months
Looking for any community input or pointers. Broadband had been stable for many months, back around April the Hub 3 started cycling every 15 mins, restarting, logging T3 errors, the occasional kernel panic but the fault was solid. Initially the Hub3 was running in modem mode with a downstream Deco router, but putting back to router mode made no difference. To cut a long story short, the Hub 3 was changed multiple times, several site visits by Virgin resulted in cable to the house being changed and finally an underground cable in a neighbours property was also changed. This didn't help but all of a sudden one night at around 1am the issue disappeared and for the next couple of months it ran fine, no cycling and internet speed good at 350mbs. However the hub3 stopped responding to pings, so the BQM stopped working and at some point the IP address changed but all was left as it was working and presumed fixed. However last week the Hub3 was powered off and the problem reappeared. Another virgin engineer attended site, said that he had just come from another customer (apparently on the same network equipment) and both of us had the same issues, an issue which he had not seen in the last 10 years. He talked about the signal integrity being perfect but the router not being assigned consecutive channels properly. Whilst onsite he referred the issue to the "Network Team", told us he could do nothing else at his level and we'd get an update soon. That was days ago, broadband is down (each cycle of the router every 15 minutes drops every connection so its as good as useless).
To me it appears like there is a rogue network config being randomly assigned, we have no control over it, we might get it, we might not, a power cycle might clear it, it might not. If anyone has any idea of what is going on, or how to get the "Network Team" to respond and more importantly fix it I'd be very appreciative.
