Lower speeds after switch to CM1000

A screen snip will show all the values. I don't quite see them all. But from what I can see, there's issues with your line. To many errors, not all the channels are locked, ofdm issues, and your power is way out of spec. You should be within 3dBmV of each other. 

A couple things you can try. 

1. remove all splitters, amplifiers, attenuators from your line.  

2. preferrably hook up directly where the coax enters your house. This removes the chance that its the wiring internal to your home.

3. inspect your line in the house if you can't move the modem to the entrance. Check for kinks, corrosion, bad/cheap connectors, wear to the coax, and loose connectors. 

If you do all that and your connection is still looking like it is, have your isp inspect your line. You're responsible for it after it enters the home which is why I recommend direct connecting it.It removes the chance of the problem being in your home. ISP's really like to blame the issue on the wiring within the home.
