Rated 5 out of 5 by from Excellent Cable Modem, happy customer I finally got around to installing the Modem: 1. Easy instructions to follow and almost automatic for BHN. 2. All I needed to do was provide the MAC address to Bright-house and it was on in a few minutes.,True DOCSIS 3.0 Functionality. Tests: Bandwidth: My Bright house speed was supposed to be 200 MBs, with the Motorola Surfboard SBG6580 maximum seped achieved was 180 MBS, now with the Linksys Model # CM3024 I have achieved 231 MBS Download and 17 Upload speeds. Wireless previously maxed out at 150MBS, now it's 182MBS. With this Modem I can achieve the full potential of what I am paying for and best of all I'll save $4 monthly for modem rental. 5 Stars for this product. Awesome.

Rated 5 out of 5 by from Fast and Easy Setup Ive had this modem for a couple weeks now and it works great. It really is an excellent modem. The setup is super easy, just plug everything up and call the cable company to give them the new mac address so they can activate it on your account. We have had several bad thunderstorms in the time Ive had this modem, losing power a few times and this modem just starts right back where it left off. One of my previous modems needed rebooting all the time but this one has been great. My previous modem was a Motorola Surfboard 3.0 so I didn't expect much of a speed change but was pleasantly surprised when see a small increase in my speed both download and upload. **See photos attached.

Rated 5 out of 5 by from Great performance, easy set up. I received the Linksys CM 3024 in return for my honest feedback. The modem is replacing an 8 year old Motorola Surfboad which I thought was great at the time. Install only took a couple minutes and I was able to configure it with my provider (Comcast/Xfinity) through my smart phone. Performance is solid even with multiple users on tablets, phones and streaming movies. I have Blast Internet from Comcast which is good for 50-75mbp but, my old modem usually kept my speed at about 50-60. I've attached a picture of my speeds within the last week of using this modem.

Rated 5 out of 5 by from Great Modem The Linksys CM3024 was probably one of the easiest and simple modems I have ever setup. If you just follow the Quick Start Guide that's provided, step by step, you should not have any problems. I connected the modem to my existing router and computer and followed Step 3 - Activation and everything connected perfectly. The footprint of the modem is a bit large, but I think that is a Plus, as the unit appears to run much cooler than my previous modem. I have 100 mbps download speed provided by my internet carrier, I tested the speed after everything was hooked up and actually got 118 mbps download test result, so the modem appeared to be working excellent. For the ease of operation and installation I would definitely recommend this modem to anyone.

Rated 5 out of 5 by from The fastest and most reliant modem on the market! The Linksys CM3024 has been a fast, reliant, top performer for me these past few weeks. I personally thought upgrading my modem would not have much of an effect on my home network...I was completely wrong. The CM3024 has not only made me exceed my data rate, it has cleared up ALL of the bogging I had encountered when streaming multiple devices and gaming concurrently. The 24 download and 8 upload bonded channels of this unit really provides the reliability I needed. If you have been looking to cut the cord on your modem rental fees, this should be your go to modem! The feature I liked most about the CM3024 was the ease of setup. Once all connections were made, I plugged in the AC adapter and let the unit do its thing. This took about 5 minutes. Then I went to my desktop and opened up a webpage. You are redirected to a page by your ISP where you enter you modem’s information. In my case, my ISP required a phone call to verify a new install and the MAC address on the back of the modem. All in all, everything took a total of 20 minutes, including the 10 minutes phone call with my ISP. That’s it! *Quick tip: If you are having problems with your computer making a connection with the new modem and do not want to go through the hassle of restarting your computer, all you have to do is open up the Command Prompt (cmd.exe) and type “ipconfig/release”, then “ipconfig/renew". This will renew your computer’s IP address with your router, as well as receive the new information from your modem/ISP. Another feature I really like with the CM3024 is the amount of information provided by the status lights. On the Receive and Send status lights, a green light signifies when you are connected to a downstream/upstream frequency, while a blue light indicates when you are connected with multi-channel bonding. Then with the Ethernet status light, green indicates when you are connected at 10/100, while blue indicates 10/100/1000. There are numerous other statuses with the lights depending on solid or blinking. A table listing all the statuses can be found in the online manual on Linksys’ website. *Quick tip: If you want to know how many bonded channels are being provided by your ISP to your new modem, type into your browser. This will provide the amount of bonded channels that are currently being used, as well as list each individual channel. The only aspect of the CM3024 that might cause problems for some users is the size. This unit is not small by any means, but for the service (24x8) and quality it provides, the larger size is needed. ISP-wise, this modem can really be used on almost any cable ISP...not just the four listed on the box (Comcast Xfinity, Time Warner, Cox, and Charter). I personally have Suddenlink, and this modem has been working flawlessly with their service…even though Suddenlink’s website specifically says only “their” list of modems will work with their service.

Rated 5 out of 5 by from Loving my Cable Modem I received this DOCSIS 3.0 Cable Modem at no cost from LINKSYS for participating in its Product Sampling Program. And, I am so glad because having this modem is saving me money on my cable bill and allowing me super fast internet access. It was so easy to connect to my computer/router and start using right out of the box. I love LINKSYS products because you can trust that they work as promised, and you know you always have a reputable source to contact for answers at any time. I am a mid-level user on the computer most of the day, and since I work at home mostly, I need reliable technology that I can understand. Thank you, LINKSYS!

Rated 5 out of 5 by from Linksys CM3024 Comcast users! Easy quick setup! The installation was simple. You can just attach the new cable modem to your cable without wasting time to call technical support, assuming your cable internet is operable. As per the user guide, simply connect the new modem and power it up. Observe the lights to confirm the new modem on your cable initiated your ISP's automatic provisioning. Now, direct connect your computer or router to the modem, power cycle the modem and open your browser. You eventually will see a screen that requests your account number and registered phone number, or log into your account. Then click "activate" and it's up and running in about 5 minutes!! I chose the Linksys CM3024 primarily due to its DOCSIS 3.0 certification and its acceptance as an approved device by Comcast. Comcast has (48) DOCSIS 3.0 devices on its approval list that are still marketed by the manufacturer for consumer purchase. Linksys seems to have gone the extra mile to assure its device is acceptable to Comcast. This specific cable modem is my best available option today and it works. Great modem and it's been running for 6 days w/o any issues. I'm using it with my Linksys WRT1900AC Smart WiFi Wireless AC Router, and Linksys SE4008 8-port Gigabit Ethernet Switch, they are awesome.

Rated 4 out of 5 by from Sleek and fast Setting up the modem was really fast, probably less than 5 minutes. Activating it through my service provider unfortunately took much longer than that. The speed is slightly faster than what is promised by my ISP. I have not had any disconnects so far. I like that the lights are small and not blindingly bright like my previous modem. The only problem seems to be that the speed over wifi does not seem to be consistent. It can be anywhere from 30-50 Mbps different from one hour to the next. I did not have this problem with the modem I was using before this. I am currently still trying to troubleshoot this issue.

*960 Mbps based on DOCSIS 3.0 throughput. Maximum speed varies depending on the service provided by the cable operator. IPv6 availability is dependent upon your ISP or service provider providing IPv6 capability.
†100/300 Mbps represent the maximum throughput you can achieve with your Internet plan provided by your cable service provider. Actual throughput will be lower than 100/300 Mbps, as this throughput is dependent on your contract with your cable service provider.
