Blast Pro download speeds ~110Mbps instead of 200Mbps

I recently upgraded to Blast Pro (from Blast).  After getting my welcome email I tried a Speedtest directly wired to the modem (not via WiFi) and only got around 110 Mbps down and around 10Mbps up.  I tried rebooting the modem and tried again and I'm still getting the same speeds.


My modem is an Arris Surfboard SB6141.  I understand this modem is not officially supported by Comcast, but it appears that many others have been able to successfully get 200+ Mbps using this model.  In fact, I asked my chat rep when I signed up for the service if I needed a new modem and he said that I did not.


Is it possible I need an updated bootfile sent to the modem?  Any help is greatly appreciated.  Thanks!
