How to Know if New Modem Will Work for New Speeds?

Hi,

I got an email from Cox yesterday informing me that my plan had been upgraded to new speeds, but that my modem would need to be upgraded in order to access those speeds (I currently have a Netgear CG4600BD which I purchased from Cox).  In a chat with support, they recommend the C6300BD as it matches the features of the existing modem (dual band WiFi Modem); however, I cannot find this modem when I attempt to look for it through their website, other than a document breaking down what the modem looks like and what the status lights indicate.  I also cannot find this model number on any website which sells modems, and the picture on the Netgear website for this modem looks completely different to the one on the Cox website. 

This lead me to look into purchasing my own modem from a separate source; however, what I'm unsure about is whether or not a router I purchase will have issues connecting to my Cox service.  For instance, if I were to (hypothetically, since it's a ridiculous price for a modem) purchase the NetGear Nighthawk C7000 dual band, wifi modem, NetGear's top of the range, would I then be able to access the new speeds of the plan without issue, or will that router not be compatible with the Cox service?  Are there factors that I need to consider beyond just maximum potential connection speeds when purchasing my own router for a Cox plan that might tell me whether "Router x" is compatible with "Plan y"?

Any help would be greatly appreciated!

    You can visit http://www.cox.com/residential/support/internet/article.cox?articleId=b2ec95d0-7ef9-11df-5590-000000000000 for more information on modem approved for use on our network and minimum requirements per service level.  Stand alone routers aren't listed there however there are other sites not affiliated with us that provide advice as well as performance reviews.

    Thanks, Chris, I've taken a look at the article and tracked down a suitable modem!

    Hi Chris,

    Sorry to bring this up again, but the article you linked to lists the modem shown here: http://www.bestbuy.com/site/netgear-ac1750-dual-band-wireless-ac-router-with-docsis-3-0-cable-modem/4483016.p?id=1219098341552&skuId=4483016

    Will that modem work properly at 300mbps on the Ultimate plan?

    Thanks!

    Beware, Pgen. I too received the email yesterday. I too checked for the correct modem, and I purchased one from Amazon, same day delivery. So my modem is activated and works fine....except, there is no increase in speed whatsoever. I did get a 16 channel modem that is approved for ultimate, but no change all. Disappointing, since I only spent 123$ on the word of COX that I needed one. Just a heads up. I got an SB6183.

    That appears to be the C6300 which should be good for increased Ultimate speeds.

    Hi rugburner,

    That's exactly what I'm worried about, thanks for sharing your experience!

    Changing the modem unfortunately doesn't automatically remove the limit from your account.  I went ahead and fixed that for you, let me know if you see any improvement after the reset.

    Just let us know if you need help with your speeds after the swap and we'll be happy to see if your account still needs to be corrected.

    Thank you. It does seem to work now. I am curious, why could you see this and figure it out in 5 minutes but the two techs I talked to yesterday when I called couldn't figure it out? Like I mentioned before, I didn't just "change the modem". I called and had it registered by cox. Then I spoke to another tech when there was no change in speed. I would think it is their responsibility to remove any limits, no? Either way, I'm glad someone over there has a clue.

    Thanks again.

    The tech that provisions the modem should indeed check for that.  While they're trained to do this they are human and may not understand that there's a difference in the service codes.  I happen to be one of our Internet product specialists so these things come naturally to myself.  Let me know if you run into any other problems.
