    I'd say something is wonky. its a technical term. :) 

    Reason I say that is that the cm600 is a 24x8 channel modem. You've only got one channel showing but even the one channel's power is way out of spec. You're power is way to low, your snr is low, and its not locking in with your provider. You said your isp is going to come check your line? That's what I'd highly recommend with your connections page.
