"No Ranging Response received" errors causing connectivity issues

Hello everyone,

 

I think I've finally resolved a bunch of my issues with my Arris T25 modem and have just one left. I seem to continually get "No Ranging Response received" errors every couple of days. The modem has some packets go through but then eventually just doesn't let any traffic go. The only way for me to fix it has been to power cycle the modem each time. My log is below. I've blanked out the MAC address, just in case it contains anything private (I'm not sure if it does). Please let me know if there's anything that can be done to help me fix this issue. Thanks!

 

Also, I'm not sure why the channel type is "DOCSIS 2.0" when it's clearly a DOCSIS 3.1 modem and I have gigabit internet with Comcast. Not sure if that's a problem too.
