Abnormally low upstream power levels combined with normal/above normal downstreams makes me wonder if there's an amplifier somewhere in the connection. That may be the case if the home has ever had lots of simultaneously active cable outlets to counteract the signal loss that comes with all the splits. If that's what's happening the ideal solution would be to put a 2-way splitter at the demarc with the modem coming off one leg then the amp on the other for the remaining outlets. If your home is a newer construction the developer may have installed a smart panel distribution system for the entire house. Without specialized knowledge as to how to best configure those they generally tend to cause more harm than good.
