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 began to notice that webpages were loading incredibly slow, and performed a speed test. The download speed had dropped to 12.88 Mbps, but the upload speed was 104.80 Mbps. I turned the router off, and unplugged it for a few minutes, then plugged it back in. After a while I did another speed test and it was 945.93 and 104.88 Mbps.
I had the same problem yesterday, 10 Sept, with speeds of 0.91 Mbps and 102.43 Mbps. Again, after cycling the router, speeds were 945.98 and 104.89 Mbps.
The same problem then hit today, so bad that I couldn't even get speed test page to load. I tried to access the Internet through the Hub 4 router on both desktop (via Ethernet), and on mobile (via WiFi). Both encountered same issue. I finally got the speed test to work on my mobile, which registered 0.10 Mbps download.
I then tried logging into my account through the My Virgin Media app. When I tried to move on from the email login page I got a "Sorry, something's gone wrong" page, with the error code: FSB50. I was able to login to the router (192.168.0.1) and ran the Network Diagnostic Tool, but all this said was that "Your home network has a few problems", without giving further details.
I've had to access My Virgin Media account through mobile data. I ran through a Service status check and received an error for broadband, with an "Intermittent signal in your area" message.
After repeating the same routine (cycling the router), the problem was fixed - to a point. unfortunately, I'm getting 1/2 my download speed, at 437.49 Mbps, while the upload speed is consistent at 104.84 Mbps.
Is it the signal itself, or the Hub 4 router? I can't be expected to repeatedly cycle the router if this is going to be a regular occurrence.

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.
