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