Recently had virgin media re-activated and was looking at my upstream/downstream power levels.
Can someone tell me if these are ok as they seem high to me:

Yes, D/S power is to high, and U/S SNR is too low unless you're in one of the new build/relay FTTP areas. I've marked for staff to take a look and advise.

Just spoke to CS who ran a speed test and advised all was fine.
Tired to explain it was the power levels being show on the hub and not throughput/speed as such, they just told me to use a wired connection.

As usual customer services are ignoring the blindingly obvious. You need a technician’s visit to either move your connection to another tap on the street cabinet or insert an attenuator into the circuit. High downstream and low upstream means you have a very good connection, but it needs adjustment to get the correct power levels.
The post has been escalated to VM staff who should get back to you today.

Hi s88urd,
Thanks for your post and apologies to hear you are having an issue with your connection.
Checking things at this end, I can see a pro-longed power level issue. We won't be able to fix this remotely so I would like to arrange for an engineer to come to take a look at this for you.
I just need to confirm the address to ensure we are booking the visit on the correct account. I have sent you a private message regarding this. Just click on the little plum envelope at the top right-hand side of the page to access your inbox.
Thanks,

Hi s88urd,
Thanks for coming back to via private message to confirm your information.
I have booked you in for the next available appointment. To view this please sign in to My Virgin Media here: My VM. Once logged in, scroll down to Orders & appointments then click on View your orders.

The technician will confirm during their visit if any of these instances apply, and if so, a £25 charge will be applied to your account.
Please ensure that someone over the age of 18 is at the property for the time the engineer is there. If the appointment is unsuitable or if anyone living at your property has tested positive for Coronavirus, has been asked to self-isolate or has flu-like symptoms then please reschedule the appointment on the same link. If you do miss the appointment for any reason, a £25 missed appointment charge will be applied to your account on the day of the appointment so it is important to reschedule if needed.

Amazing service.
Engineer has just attended and sorted out the power issues.
Really professional and knowledgeable engineer.
Thanks for sorting this out so quickly, here are my stats now:
