Downstream power levels are way too high

You’re mixed up at what levels you’re looking at. If you see 55, thats your upstream, not your downstream, that’s entirely too high and an attenuators is only going to make it even higher and more out of spec. It really may seem like your talking a foreign language if you have your levels backwards. Post all of your levels, post how your cables are ran (splitters, amps etc) because it may have nothing to do with outside. With the pandemic, it’s going to get harder to get a tech out for something that may be unnecessary. Comcast acceptable levels are 10 to -10 downstream and 35-51 upstream

Thanks for your reply, my apologies, I am indeed getting the history of this issue mixed up with a newer issue. So my OP makes very little sense. 

 

Several months ago I was experienceing upstream power levels at 56+. I somewhat corrected this by introducing more splitters and that moved my power levels to around 50. 

 

The other day I upgraded my xfinity plan and needed to upgrade my current modem to a Docsis 3.1 to handle the new speeds. Upon logging in to my modems stats page I noticed that the downstream power levels were around 20-22 on all 31 channels. 

 

My apologies, there are two diffent issues here and I was getting past issues mixed up with current issues. However still, if you could please comment on what may be causing my downstream power levels to now be too high, I would appreciate it? Could the additional splitter I added with my previous modem be causing this?
