Regular drops in speed and repeated router reboots

I've been having issues with my broadband speed for about a week now. I'm on Gig1 full fibe, with a Hub 4 router, and regularly get 950-985 Mbps download and about 100 Mbps upload. On 5 Sept, I bega...

    The preferred Power levels for the 3.1 Downstream  are -7 to +7 dBmV 

    Here the figure is -14.6 dBmV, as this is a logarithmic scale, the received signal is a tiny fraction of what is expected,
    this is likely the root cause of your variable speed issues.

    You can try to request an engineer to be sent to rectify this, but I'd not be surprised if this turns out to be a fault in a street cabinet or even further back in the network that is affecting many customers in your locality.

Although the Downstream power levels are strong, the SNR ratio is close to or at the lower limits.

Is there a known service fault in your locality - (do try both) ?
Call 0800 561 0061 – this is an automated number.

Speed test the service to a Router mode Hub(3/4/5) + your device with the link below.

Once the test begins click on: Run full test to include: Latency, Jitter, Packet loss & Upload speed

The speed at the Hub should reflect your subscription

The automated number indicated that there were NO issues in the area. Confusingly, following the VM link, it stated that there was an "Intermittent signal in your area. We’re looking into it. Check back here after 21 hours, and if there’s still an issue we’ll help you book an engineer."

This was the result using the check VM speed test tool.
Latency 16.7 ms
Jitter 0.52 ms
Download 74.0 Mbps
Upload 103 Mbps

Do I wait nearly 24-hours, or book an engineer? This has been ongoing for nearly a week.
