Cox is throttling speeds of DOCSIS 3.0 modems

I used to have 250-350Mbps down 2 years ago but Cox has throttled down some older DOCSIS 3.0 modems to only have access to the essential 150mbps speed. If Cox didn't have a monopoly on internet service providers in my area I'd switch ASAP. Probably just trying to sell more of their junk modem rentals to unwitting customers and take advantage of their lack of knowledge.

Hello. You can find information about approved modems here: www.cox.com/.../cox-certified-cable-modems.html. -Allan, Cox Support Forums Moderator.

If you are throttled down, it has to do with the version of D3 modem you are using. I am using an Arris 2460, 24 DS and 8 US channels, and I get 270 - 290 down consistently.

Yep. I used to have the better service 300-350+ but now I'm locked out of it so they can generate more e-waste.

I also have an older 3.0 modem that I was using on Cox's 250 plan (for a long time).  A few months ago I came across their new certified cable modems document to find out that my modem was now only supported up to 150.  Unfortunately Cox seemed OK letting me continue to pay for 250 - I've downgraded to 150 for the time being, but only because I noticed the issue, not because Cox came to me and told me of the change. 

Yes, my modem is old and I'll eventually get an upgrade to 3.1, but I'm a little disappointed that Cox wasn't a little more proactive once they changed their standards.

I apologize if you were not made aware of the change.
March 29, 2022 – Customers of Cox Communications’ most popular service tier can now enjoy speeds up to 66.7 percent faster at no extra charge. To enjoy these increased download speeds – from 150 Mbps to 250 Mbps – eligible customers just need to reset their modems.

The CG3000d  is rated for the Essential tier of service and slower. The PREFERRED level of Internet requires a better modem. YOURS is 8 downstream x 4 upstream, to give you an idea, MY modem is 5 years old, (I think), It's a DG2460, 24 downstream, by 8 upstream channels. You can find more information on https://www.cox.com/residential/support/cox-certified-cable-modems.html .

Your modem will have to be replaced if you want faster speeds.

You just continued a conversation from 12 months ago.  Where have you been for the last year?  Deployed overseas? Jail? Coma?
