slow internet speeds

 

I have been having issues with internet speeds.  I am supposed to have 32 locked downstream channels.  Most of the time my speed drops from 200mb to around 30mb as connections to channels 30-32 get dropped which I assume is due to a large number of uncorrected packet errors.   Even if channels are not dropped, download speed drops to around 30mb when there are a high number of uncorrected packet errors.   I was having this issue on my SB6190 cable modem.  Switched to a CM700.    Problem does not seem to be modem issue.  Any suggestions to solve problem appreciated

Here are modem stats
