Upstream and Downstream Channels

[FRESKO]

Does anyone know anything about upstream and downstream channels? My internet has completely awful today. I usually get 80 down and 20 up but today im getting 20 down and 2 up. Ive tried talking to comcast but as usual they never help. 


Here are my channels:

Your power is WWWWAAAAAAAAYYYYY off, it is likely an issue with too many or too few splitters between your modem and your main line.  This is a common issue, I have 2 * 2 way splitters in my outside box.  the first splits the mainline, it then goes into the second and into the cable modem.  So i have one two way splitter between the main line and my modem

 

Here is my channels and signals, everything working perfect.
