D-Link DOCSIS 3.0 Cable Modem (DCM-301) Compatible with Comcast Xfinity, Time Warner Cable, Charter, Cox, Cablevision, and More

Decided to buy a modem instead of renting one and this was on the approved list of cable modems from my provider. The unit is nice and compact compared to the one I was using from the cable company. I also like that there are no flashing lights only solid green LED that let you know the unit is on and connected. Getting up and running took a bit of effort not because of the unit but the customer service rep I had to call to get it registered kept mixing up the numbers and kept asking me for another S/N since it wasn't accepting it. Turns out they had to input it was a retail modem and not a company modem. Did a speed test and this modem gave me faster download speeds and webpages pop up quicker which is a nice bonus since both the old modem and this one are both Docsis 3.0. I can't say as to the longevity of the unit since I just got it but I am happy with my purchase and would buy again. Update...Two years later and still going strong. Solid connection. Speed is at the top of the range with my provider (Cox). The number of times I had to reset the unit I can count on one hand. I see the price has dropped. I would buy again if I ever needed to replace the current one.

So far it works great. I've had it for three days. When I did a speed test I actually got an insane speed compared to my cable modem from Time Warner I'm sure they will adjust that though. I was barely getting 30 megabytes per second and it went 50+ each time I tested it on the first day. I noticed a theme though. I do wonder if Time Warner Cable sends out some little signal to make these not work after a while. The common theme here, and it doesn't matter the brand, everyone who does complain about their modem is that it does not work after some time. It is ironic that when you get a cable modem usually from the cable provider you can end up with a cable modem for years until they upgrade and you never really have issues with the modem itself I mean. Maybe once in a while. But my experience has been pretty smooth over the years at home using the modem provided by the cable company. If this one goes out in 3 to 4 months or within the year, I can't help but think that the cable company does something to ruin them. It's not in their best interest for you to save monthly especially when they have millions of subscribers. Anyways I got the SquareTrade warranty on it so we'll see how it goes. I could just be crazy, but at the same time there is that glaring fact, no matter the brand, so it's worth noting. Also why only ones they approve of? If a manufacturer makes a modem and its FCC compliant and can handle the cable internet as stated, you should be able to use whatever modem you want just like an oil filter aftermarket or an air filter aftermarket in your vehicle. As long as it's built to code it should be perfectly fine. They shouldn't dictate which ones you should be able to use as long as it does what it claims. So is TW an evil and greedy cable company that makes billions a year profit (like Verizon) and wants you to pay that modem fee, or are some simply having an innocent mishap with their cable modem? We'll see.

Bought the D-Link DOCSIS 3.0 Cable Modem (DCM-301) of $30 as the price was right and I had nothing to lose. It was simple enough to connect the ethernet cable and the coaxial to the back and plug it in. I phoned Optimum (I reside in the Bronx, NY) and gave them the MAC address. The customer service representative asked me for the brand of the modem and if it is a DOCSIS 3.0. I confirmed both and confirmed the unit was plugged in and turned on. The rep seemed a little surprised that he was able to connect to the modem instantly and restart it right away. With small talk included the entire set up took less than 5 minutes. The modem intergraded seamlessly with the Optimum wireless router, and all of the wired and wireless devices in my home. I do not notice a difference between the Optimum branded Arris TM822 modem I was paying $4.95 a month for and this D-Link modem. It has a small footprint, is sleek, low profile and hardly noticeable compared to the Arris it replaced. I recommend this modem.

I received this modem from Amazon earlier this week and I'm totally happy with its performance. My old modem was a DOCSIS 2 WiFi modem and this one is DOCSIS 3 so the improvements were immediately apparent after setting it up and getting it working. The setup only required calling my ISP (WOW) and giving them the MAC address and within 5 minutes the modem was up and running. The original modem/router from my ISP wouldn't allow for setting static IP addresses and their refusal to let me into the router to change settings beyond changing SSID, password and turning off the WiFi function is the reason I went with my own separate Modem and WiFi Router, not to mention the $7.00 per month lease fee . As one other reviewer stated, the IP address and password for this modem is not easily found but is required if you want to change the password from the default one (the default password was "password", DUH) and turn on the firewall from it's default of OFF. (Thank You A. Benson!!) I'm not sure why D-Link wouldn't routinely supply that info and instructions how to use it. There is a reset button on the back if you mess it up that will bring you back to the unit's default settings. I used the same D-Link DIR-655 WiFi router with the DCM-301 that I used with my ISP's original unit after turning off the original modem/router's WiFi function. It took two hours on the phone with WOW to get the ability to get into their router as they don't like people messing around inside their equipment even if we are technically competent to do so, more reason to get my own stuff. I only gave this modem 4 stars because of the lack of info about getting into it to customize its settings. Performance wise, five stars would be in order.

I replaced the cable modem supplied by Comcast with this to save the $10/month "rental" fee, and not only does this work like a champ, as a bonus it fixed problems I was having with Comcast's TV signal. To install I just followed the included instructions then dropped my old cable modem off at a Comcast store. No need call to what in the industry laughably calls customer "service". When Comcast "upgraded" me to an encrypted TV signal, it never quite worked right, even though the signal strength reported was good. Pictures kept pixelating and freezing. I lived with it because for the most part I'm a cord-cutter, but occasionally it's important to have access to local broadcast TV. After months of putting up with it, I decided to cancel my TV service and while I was at it, replace my cable modem to save the fee. I replaced the modem first with this thing, and amazingly the problems I had with Comcast's TV decoder box just disappeared. Apparently the cable modem Comcast provided was generating interference with the decoder. All you can ask of a device like this are three things: (1) it does what it's supposed to; (2) it's easy to install; and (3) it doesn't cause any other problems after you've installed it. This delivers on all three so I'm giving it five stars.

I bought this modem for Xfinity in June. It is now September. That's three months. The modem worked fine at first. I was getting 60mbps upload and 6mbps down. Then all of the sudden I tired to use it and the up speed dropped off a cliff. Now I'm lucky if I get 1mbps up. Xfinitity sent out a technician and with his modem, he was able to get 30mbps up! He then looked me dead in the eyes and said it was my D-Link DOCSIS 3.0 Cable Modem (DCM-301). I called D-Link and they told me the device was defective and to return it to the company I bought it from. I've clicked around Amazon, but to no avail. I can't return it. Now D-Link is going to charge me shipping to return it. Life's lived in a cold dark world with no happiness anywhere.

Great Product! Easy Plus and Play setting. I plugged it in and after calling the cable company to give them the MAC address it was up and running. And it performs better (faster in terms of ping and response time as my bandwidth is capped) than the Cable Company's cable model which I used to pay $15.00 per month for... I later logged on to the device to see what I can customize.... there is very little to change and customize on this device... It simply works and I think that is awesome... Instead of buying a combination cable-model + Router device I have learned it is much smarter to buy two separate devices. In that case if/when I move or if one of the two devices stops working or gets old I have more flexibility... The companion wireless router I purchased to work with this device is NETGEAR N300 Wi-Fi Router with High Power 5dBi External Antennas (WNR2020v2) That one is super easy to setup and it has a powerful radio with two large external antennae... For $21:00 you can't find a better brand name wireless router....

Installed yesterday. It took about 10-15 minutes to complete. You do not need a computer science diploma to do this. Just connect the coaxial cable, the ethernet cable, and the power adapter. On your computer monitor, you would enter your cable account info and the MAC number, which is located underneath the cable modem. In a few minutes, you are back in business, faster and more economical. I am with Optimum. That is the only choice in my community. I have been paying $5 per month renting their modem for over 20 years. I have paid 1200+ dollars for renting a trouble prone modem! What a waste! Their modem also rated as 300+ mbs. However, once connected, I found my new modem performs much faster. All 4 computers, 2 cell phones, and a TV are faster. I already returned the rented old modem to Optimum. Can't be happier!

now not in use because wanted rj11to coxial convertor
