Sudden drop in speed from 1Gig

[MckeithyB]

I've recently upgraded to 1Gig. Today at 3.45 speeds went from 960Mbps to 3-4

I reported it, and apparently there's a problem with the modem (hub4) , although I'm not convinced it was even investigated. Anyhow an engineer is booked for Monday.

All the metrics on the modem status look good apart from the docsis 3.1 QAM1024.

Problem in my area (KT5) or genuine problem with the new modem?

Wired connection only.Modem mode. All the usual problem solving steps undertaken.

Cheers

This is not a local fault, I have friends who don't live near me and we have a broadband graph which shows the same problem in the night it seem to resolve itself but then comes back during the day. Other graphs have been posted showing the problem, also some people with 1 gig connections are lucky to get a couple of megs download

I'm on the same boat. My gig speed goes down to a crawling 1-10mbps during midday - midnight for the past 4-5 days. Somehow using a VPN brings my speed back up to a usable 600mbps. I've got an engineer coming tomorrow but I expect nothing from it as the issue is clearly nothing to do with my setup.

You can see the pattern repeating on a 24 hour cycle.

not just for me but for many users.

Hi @MckeithyB @msun @Barrerayy @Stormphoenix @Gh4z @bobgarb,

Our support team are looking for some help with the network investigation and logging.

Could you all post static BQM graphs for the past 48 hours making sure the time and date are clear?

Please also include a live BQM graph to help us with the monitoring.

Thanks,

Melissa

How can i make one of these graphs? Do i need to enable icmp on my router as i got the superhub in modem mode.

You do indeed!

When you've done that - head over to ThinkBroadband and set one up from there! (instructions on the TB site)

 As suggested on other threads, my feeling was that this was an issue with ThinkBroadBand (cloudflare?) to Virgin.

So far today - things have been behaving themselves. I've run several speed tests, and they've all returned 930Mbps+
