I've had this intermittent problem occur twice now and need to know what's going on as I'm currently trying to work from home.
On Friday the 05-JUN-2020 is when it first occurred and it only lasted about 1-2 hours and went away after resetting the hub twice. It then didn't happen over the weekend and was fine this morning also, but now its been down since midday today (so 7 hours as of posting this).
My download speed is still very fast, 373.9Mbps, but my upload speed is practically non-existent at below 0.1Mbps. This as you can imagine is causing a lot of issues.
Now I've tried all the classic fixes. The virgin media status says there are no known issues and when i do the test on their site it says all is fine. I then do a speed test and get the same results roughly every time. Three times today I've powered down the hub, left it for 15 minutes and then powered it back on. No fix. The front light is pink as I am running in modem mode and no other lights are showing. The hub is then connected directly to my PC as well as a Deco mesh wifi network system, BOTH of which show the same issue. All cables are checked and secure.
downstream power levels really high, and upstream QAM dropping down to 32, would first make sure all coax (white cables) are finger tight at all connections, highly likely this would require a tech to attend, this can be arranged by the forum staff or calling into virginmedia

I've checked all connections inside and outside with no issues from what I can tell. I did a hardware reboot (pin hole) again and went out for 30-40 minutes and now I'm back the upload is at least workable but both are low. 83.7Mbps down and 3.82Mbps up even though I should and normal do get 350Mbps down and 12-15Mbps up.
There surely must be an issue in the area as it worked perfectly over the weekend? I also had a chat with someone on twitter who is one postcode over from me (so within 0.5-10 miles away) and he was having the exact same issue (204 down and 0.04 up). Will give it overnight and see how it is tomorrow but otherwise will take your advice to call them and see if they can get someone out to have a look.
I've got a Virgin tech coming out tomorrow to have a look. The issue is the problem is intermittent, so in the event that it is suddenly working again when he is here (like it was working perfectly last night), is there anything I should specifically point them towards? Not hating on Virgin media, but in my previous experiences years ago when I lived with my parents they just used to kind of wiggle the cables, reset the router, stick a filter on the back and go "that should do it" and then the problem would reappear again a day later.
I recognised the issue today at around 15:30 which ties in with todays graph for packet loss and latency spikes. I've been doing a lot of resets and different things with Virgin over the phone from about 4:30 onwards so that has screwed the graph massively.
The second graph shows yesterday so I will be very interested to see if it improves around the same time of day.
