Internet constantly dropping out past year, flashing green light on HUB 5.

Question

I've had a reoccurring issue with my broadband connection over the past year (maybe slightly longer) where my internet connection just suddenly drops and after I reboot/reset the router I'm greeted with a green flashing light. This can go on for hours or in a couple of instances days. I had an engineer round a few months ago and had my connections checked in my premises all of which are apparently fine. At this point, and after looking at my routers settings, I believe it's an that's occurring at the cabinet or somewhere else.

Here is some router information if it helps;

5 hours no response. 20 minutes on the phone no answer. Not only is your ISP service rubbish it appears your customer care is as well. All I have to do is look at the router settings to know you're overselling bandwidth to customers, funny how these intermittent issues started to occur when I refused to renew my contract.

Is there really no data for the down/up channels tables ?

Can you check for any “known network faults in your location - Look in 2 places

1) Try the “check service,”Area status webpage (https://www.virginmedia.com/help/service-status)

2) Then also Try the “free & automated” Service Status number - 0800 561 0061 - which usually gives the most up to date info. and tells you of more local issues and fix estimates, down to street cab/ postcode level.

A VM person will respond in due course

Thanks for the reply.I've checked the website and used that number numerous times not just today but every time this fault occurs.And yes there really is no data for either of those channels.
