Hi all this is my first post here so hopefully I am providing useful information. I am on a Virgin Media M500 package and I'm seeing large variations in the speed of my service. According to fast.com I had 14 Mbps last night, 510Mbps this morning and I'm back down to 20 Mbps as I type this message. My upload speed seems less varied around 30Mbps.
Note I am not changing any of my configuration, so I would think the variation in speed is most likely coming from outside my home.
My setup is:
I've tested speed using fast.com, thinkbroadband, samknows and the AmpliFi's built-in speed tests. The built-in test rules out any fluctuations caused by WiFi.
Accessing Virgin's own check https://care.virginmedia.com/care/check-services gives me the error "Looks like you’re having trouble connecting to the Hub". I am wondering if that's because it's in modem mode.
I've just signed up to thinkbroadband's quality monitor as attached.
Also attached are my latest superhub stats. Does anyone have any suggestions for what I could look at?
Many thanks.

Your BQM shows something on the VM network was fixed around 11pm. I would suggest you reboot your Hub and check the latest set of stats.

Thanks @Adduxi.
This is common for me: the speed is good first thing in the morning and then gets progressively slower into the evening. For posterity, I am attaching a static version of my BQM now as the one above is live. Also attached are my router stats when my connection is good.
I'll keep an eye on it this evening to see if it dips again. It's frustrating because of how frequently it happens and then is magically fixed again. Because it never lasts more than 24 hours, Virgin don't consider it an issue.

Good morning @michrome,
Welcome to the forums and thank you for taking the time to post.
I am sorry to hear that you have had some issues with your services.
Do you possibly have a live BQM that you could provide us?
Kind regards,
Zak_M

Hey again @Zak_M.
It's slowed right down again now, and there is a spike on the BQM graph. What I can say is it seems to be timed with the kids coming home from school and turning on the AppleTV to watch Netflix. Or it could be coincidence because every kid in the area is coming home from school and turning on their TV … but surely an M500 package should allow us to watch Netflix without noticeably slowing down general web browsing and throwing errors?

Your connection is extremely sick.
1, There is extreme packet loss at peak times
2. The RS errors on some channels show that there is a great deal of noise on the signal
You are going to need a techician visit to sort these problems.

Thanks @jpeg1. It just completely fell over just now, so I called Virgin and they told me to turn it off an on again which seems to have revived it for now.
I have all kinds of theories: could my Superhub be sick? Everything else on my network was able to connect to each other but 192.168.100.1 wasn't responding … almost as if the web server in the modem (for the admin pages) had fallen over. The hub was also pretty warm - not sure if that's usual or not.
