Here is my upstream levels as of this time (9:27pm PDT and net is working at the moment)
Ranging service ID 5982
Symbol rate 2.560 Msym/sec
Power level 50 dBmV
That's pushing the limits, its probably 52-53db at the hottest point of the day. You really like the power level around the 45db range. As SHoTTa35 said, if there is splitters that can be removed, that can help drop the upstream power level a bit. Also once the cable reaches your house, is it connected to a two way splitter? with one line running to cable modem, and second line to another splitter if you have multiple tv's to connect? If not, that's what you really want to keep the cable modems signal levels as best as possible.
