I read that 49 is in spec for upstream and it doesn't fluctuate any higher than 49. I only have Xfinity internet so I already removed all the splitters. Just a ground block from the line outside directly to one coax going directly to the modem.

Hi. Equipment includes a CM1000 modem. I'm wondering what you guys can make of this. I just activated my service with Xfinity. I ordered 250Mbs. The line outside goes into one filter and directly to one line in the house into the modem. There are no splitters. The line in the house is only a couple years old with no damage and worked fine with DirecTV. No TV service any longer just xfinity internet. Power levels for downstream/upstream are all seemingly great. After resetting the modem factory or regular it will juggle a couple channels with the vast majority locked but stays on the same channel and gives 50-300Mbs speeds with drastic swings.
Then it will lock to the same 15-32Mbs (32 cap) speeds without anything changing after just a few minutes of up time. Which I assume is some sort of throttle on Xfinity's end because of noise on the line or something? 90% of the channels have nearly the exact same ratio of Correctable and Uncorrectable Codewords and same amounts. The Uncorrectable to correctable ratio for these nearly identical channels is is 4.15 to 1.
I'm also not getting any warnings or critical messages in the event log on my modem. Just notices.
Is this a local node issue? Or a modem issue? Or a line issue? Can someone offer tips for a new Xfinity customer?
Okay. It doesn't seem to want to accept HTML here and it won't let me upload an image here because it shows up as a giant grey triangle. But here is the link to my CM1000 channel/power page
