    2010 : ) Wireless Cable Gateway CG3000D DOCSIS 3.0 Question w/ Cox


    I am currently using a combo modem/ router DOCSIS 3.0 2016 Netgear AC1900 WiFi Modem-Dual Band (C6300BD) supplied by Cox included (no monthly rental charge) in a cable/ internet package. This summer I will be dissolving that contract and will have to give that combo modem back. I also have that I own a DOCSIS 3.0 2010 Wireless Cable Gateway CG3000D cable modem. Minimum requirement to use Cox Internet is DOCSIS 3.0. I do not stream into the next room or for the moment do not use say Netfix though that could be in my future. I do occasionally use the current DOCSIS 3.0 2016 Netgear AC1900 WiFi Modem-Dual Band (C6300BD) to connect my phone with WiFI.

    My question is how necessary is it to use a modem now a days that is both a cable modem and a router. Can I get by just with using the DOCSIS 3.0 2010 Wireless Cable Gateway CG3000D cable modem or is that a bad idea.

    If it's a bad idea I won't rent from Cox when I make the switch this summer but would buy my own.

    If anyone has anything good or bad to say about the Cox approved modems that would be appreciated partiulalry regarding bang for the buck and I certainly do not need the latest and greates. TIA.

    The 6300BD is on the list... I believe a cable gateway still has to have a modem to get the signal from the ISP. Stick to the Netgear brand and buy your own equipment, you will be happier in the long run. Here is link to a refurb unit, they are pretty cheap.

    Thanks for responding. Right. I knew that the 6300BD is still recommended. I really did not check the list to see if the 10 year old CG3000D was still there. If I were to buy new I guess I am thinking that the 6300BD now three plus years old is getting a little long in the tooth ( it has never been flashed ) and I was thinking of getting something a little newer without breaking the bank. Even if the 10 year old CG3000D is not on the list any more it is still a DOCSIS 3.0. Do you have an opinion of using just a cable modem and not a cable modem/ router combo? TIA.

    My experience has led me to use my own router for wifi around the house to all my devices, a 6300 model Netgear. It is attached to my ISP docsis 3.0 modem supplied at no charge. The dual band router gives me options to run 2.4 and 5g with two guest networks.

    I'm curious as to why you think the CG3000D is just a modem and not a router? It is a combination cable modem (8x4 good for 340 Mbps internet spped), Ethernet router with 4 wired gigabit ports, WiFi access point with N450 Mbps. It also has 1 USB port for media sharing.

    This modem/router would be fine for basic internet surfing, email, and non-HD video streaming. Just make sure that you are not paying for extra internet bandwidth that this modem is not capable of. 400Mbps would be the absolute fastest internet you would want to pay for, and that will still get throttled down to 340Mbps by this modem. It should still be compatible with COX internet.

    You're right. I don't know for sure. I did not re-check the specs of the 10 year old CG3000D before posting. I only recalled that the Cox store made a big deal out of "giving" me the 2016 Netgear AC1900 when I switched services when I told them that I only had the CG3000D. Now that I think about it I think the big deal that they were making was the fact that the Netgear AC1900 was dual band and that the CG3000D is not : )

    I am still curious about all those new fangled modems/ routers that are listed on the Cox page and might still give them a look see. Call me a snob but it kinda rubs the wrong way using a a 10 year old modem/ router. Do the new ones make coffee?
