Modem power Reset When Upload

If modem is power resetting unless I use QOS in my router to limit the upload speed...Does that mean my modem lacks the capability to control flow and therefore POWER RESETS?  SB6121 Modem currently.  I find it hard to believe that a modem manufacturer would simply drop kick the modem into a power reset because an upload speed is being exceeded.  Do they make modems that don't hard reset due to excessive upload speeds?

    The 6121 is no longer an approved modem. It actually fell off the approved list a year or so ago, you're probably still able to use it, as it's grandfathered on your account, but it's definitely no longer approved. You will want to replace it!    www.cox.com/.../cox-certified-cable-modems.html
