The critical 3/4 errors is the modem telling you that there is an issue with the internet signal. 

You need to contact the internet service provider, talk to a level 2 technician (a level 1 will just see you have internet and say its not them). Inform them that you do have internet, but you have constant drops, and see numerous critical 3 errors and would like them to clear those out.

The value of power for downstream channels should be between -15dBmV and 15dBmV. If the value of power is not in that range, it means the line quality of that channel is not good. The value of power for upstream channels should be smaller than 50dBmV and the value would be between 30dBmV and 45dBmV normally. If the value of power is larger than 50dBmV, it means the line quality of that channel is not good. If there is 1 or more channels with bad line quality, the overall line quality may be bad which can cause disconnects.

@CMartNetwork i just set mines up yesterday and 3 seperate times since then I'm having the same problems.  I can't even manage it through the internet id address to reboot the the router and secondly the chat customer care care people seem like they can't read I'm not getting any good help with the issue of signing into the tether app i have to go to a web page instead of a direct connection with the app. WTF!

The Tether app does not support the CR700. Your computer is probably having issues accessing the CR700, use a different device like a tablet or your smartphone with a browser.
