Hi all and long time no see.
I'm hoping somebody on here can help and save me another call to CS. I actually can't fault virgin CS this time but I have a bit of an anxiety about calling people I don't know so would like to avoid the call If I can. Earlier today I received one of those self install packs with the SH2ac and rejoined virgin supposedly at 100mb. I'm only getting 6mb of that and even that took a phone call to an actual customer service person because the automated system failed to activate my router, as I said above I dislike calling people I don't know but to give the CS rep his due he seemed good to me.
Now after the call I noticed the connection seemed sluggish compared to the BT fibre I have just switched from and I've had a few page not found errors so I have performed a speed test (or 10) and get a fairly consistent 6mb down 6mb up. lowest down speed was 3mb but this was an anomaly as far as I could tell. My ping has varied from 12ms to 80ms so not terrible but not great at its lowest, still not what I would expect from a suffering connection as I would expect to see a ping in the 100s.
A quick google would seem to suggest my power levels are too high but I have to admit to knowing little to nothing about this side of things.
I've attached screenshots of both my download and upload power levels. Can anybody with the correct smarts let me know whats too high and/or too low so if I do have to call CS I will at least have all the relevant info to hand?
Also would old wiring be a likely cause of this? I expressed some concern to the original person who said I would get a self install kit that the cover of the inlet to the property had Nynex branding and I don't think we have had Nynex here since 2001.

Thanks in advance.
