S33 dropping connection, very hot. 

 

I have had it hooked up for 4 days and I get a dropped connection and buffering all the time. I went from 40mbps DSL to 300mbps cable and I feel like I had better internet with the DSL. 

Modem is running around 160 degrees internally, consistent logs show sync failure

Community, any recommendations on a modem that wont give me troubles right out of the box?

got a screensnip of thecable connections page? 

Since you are experiencing with intermittent internet connection, I suggest you to check the cable signals to make sure all the signals are in range.

To check the cable signals, follow the troubleshooting steps in the below given link:

  3. Verify no property damage or bodily injury occurred.
