Upgraded modem to Docsis 3.0 but no increase in mbps

Today I upgraded my modem from Docsis 2.0 to Docsis 3.0 (Motorola SB6141) and when I do the Ookla speed test on the Cox site I am only getting between 20 to 25 mbps, which is the same I was getting with my old Docsis 2.0 modem.  I am paying for the 50 mbps plan... how do I get the speeds closer to 50 mbps?  I unplugged my router and am connected directly to the modem.

Hi jl8422, have you registered the modem with a Cox rep yet?

Hi Mike, yes I did call in yesterday to register the new modem. I gave the rep the Customer S/N and the HFC MAC ID.

Still getting around 20-25 mbps.  What else needs to be done?

Send an email to cox.help@cox.com and ask them to change the code in your account

I was stuck at 32 MBPS with my 6141 and increased to 60 MBPS after they changed the code. "Preferred" account.
