Arris SBG10 Modem Firmware update

I tried going through the support chat but had no luck. I am just trying to find if my modem has the currently supported firmware version. They tried selling me the cox support package, but I. Perfectly capable of troubleshooting my own hardware.

If I could get an answer on how to find out the current firmware supported, and/or get it pushed to my modem that would be great!
