Virgin upgrade works has messed up power levels

[madmanx]

Hi had some work on my local network done today as it says it was doing upgrade work to improve the services, 

But after being down for half the day when the hub came back online I saw the power levels are way out if sync now. The downstream before was between 0 and 3dbmv and the upstream dbmv was about 38 dmbv, now the downstream is +10 dbmv and the upstream is now around 34dbmv, do I need an engineer to fix it? I have a 6db forward path attenuater fitted at back of hub which i could change to a 10db forward path attenuator to bring down the downstream power levels but its the upstream I'm concerned about as its only 34dbmv?

Have I a problem now?

Hi as u can see internet is still not right went down twice last night

[madmanx]

Sorry I pressed on solution by mistake can forum.team.change it as it hasn't been fixed.

Hey madmanx, thank you for reaching out and I am so sorry to hear about this.

I have just taken a look at our side and everything is look great on our side, your levels are showing great.

How has it been over the last few days, still the same? Cheers

Hi upstream qam keeps changing, can go from qam64 to qam16 then up to qam32 then back up to 64qam then, can keep changing qam like every few minutes but generally only seems to affect one upstream channel the lowest frequency one. When it drops to 16qam I get packet loss on my thinkbroadband quality monitor, is this due to noise on upstream? And would I be right in thinking its a network problem, rather then being a problem that's only affecting me? Any help be nice, also my downstream power levels are going over 10db but forum staff saying that my power levels are great?
