I have had a look at my downstream power levels on my Hub 3.0. I believe that the addition of a 3dB forward path attenuator (or maybe more?) might be needed. I realise my levels are still within the -6 & +10 dBmV band, but surely getting them closer to what I believe the optimal level of 0 dBmV would be beneficial?
Please can I get some guidance on where best to source one from. Are they something that can be posted to me by Virgin, or can I purchase one directly from somewhere? I have found some by searching the internet but they often refer to satellite and not cable. Is there a difference?
Please see screenshots below of my stats for reference:
Generally no, the connection is mostly fine, but there are certainly times when especially the upload speed drops significantly. My guess is that the slow-downs have been more related to potential over-utilisation in our area than our local connection to the network. I was just wondering if getting the downstream levels closer to 0 would give it more headroom to drift before causing an issue.
Many thanks for your continued interest in helping me. I have had a BQM setup for a few years now. I tried following up utilisation issues that were evident in the BQM in the past, via this forum, without success at the time. Since the reduction in lockdown requirements the BQM has been looking reasonably good (for a DOCSIS connection).
My original post was not intended to be for the purpose of looking into over-utilisation though.
Below is my current BQM and below that an example of previous over-utilisation issues:
Many thanks for your response. I take on board the general consensus of all responses so far that if the power levels are within -6 to +10 dBmV then there if little point in trying to get the downstream level to 0 dBmV. That said, I may still experiment to see if I get a stop to the few Post RS Errors.

Below shows how long it has been since my last re-boot.
