CM600 upload light turns amber

Model CM600 Just did a factory reset. Maybe that will solve the prolem that the UPLOAD LIGHT turns amber after a while. Also, before I did the reset, the modem would just not work and lights flash....

you signal coming in has issues. Please post your power table and DOCSIS event logs from the GUI.

 

Amber on US means it is not bonded.

    thanks. if you see your US power, it is too high (it is supposed to be bonded 3 or 4 US channels, but you have only 1).

     

    Either you need to remove splitters in your house or ask ISP to decrease attenuation to give you extra few dBs margin.
