Modems aren’t user updatable. Its part of the docsis spec. 

So sparklight blaming it on that is just them getting you off the phone. 

First though, test your speeds directly off the modem (without a router connected) and see what you get. Make sure it is indeed modem/ISP related and not a slow router.

If there is a firmware update available and the phone techs get an error pushing it then ask to escalate.  There are many things that either they don’t know how to do or are restricted from doing.
