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
