Depending upon what your ISP supports for your upstream configuration, no all channels will be locked in. I have 50Mpbs up link and mine is only using 4 channels.
Have the ISP check the signal and line quality UP to the modem.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.

I was checking the channels on my CM700 because I had noticed my internet has been intermittently dropping recently, and I saw that only 5 of 8 upstream channels are locked.
How can I make sure that all 8 of my upstream channels are locked? I do not know much about routers/modems so any help at all would be greatly appreciated.
