This Linksys CM3024 replaced my Motorola Arris SB6141. Setup was simple, as with any cable modem, but it's the activation where many have their headaches. Not with this Linksys CM3024. I simply traded cables with my previous SB6141, powered it up, waited a couple minutes then power-cycled it again and was able to follow through with Comcast's web activation. Not having to pickup that phone was nice. As for speed and overall performance, there has been no slow downs, drops or anything that would cast doubt on the CM3024. I still consider early in the game so if my opinion changes by any means I will certainly update this. I received this as a free sample from Linksys in exchange for my honest feedback and I am honestly satisfied with it and I definitely give this a thumbs up. For cable modems, I am a Motorola die hard but I will gladly say this: It has been an awesome replacement and I will not be swapping it back.

I received this modem for free as a member of the Linksys Friends + Family Program in exchange for my honest feedback. I replaced my ISP rented modem and the my performance and reliability immediately increased. My current package provides upto 300Mbs, and i am able to acheive that without a hitch as i was unable to get speeds anywhere near that with the rental. The modem has been running for a week with no signs of degraded performance and required no reboots, the rental was rebooted atleast 3 times a week. The only downside of the modem is the size, its very bulky. The modem is paired with the Linksys WRT3200ACM router. I have used many Linksys products and will continue to do so.

I received this modem as a free sample from Linksys in exchange for my honest feedback. Unboxing was typical. Included is the modem, AC adapter (which isn't too big), cat5e network cable, and quick start guide if you need it. Replaced my surfboard sb6121 with this linksys modem. PROS: -Offers great speed. Currently on 75mbit/10mbit cable but soon to upgrade to 150mbit/20mbit and this modem will easily handle those speeds also. -Nicely designed with green and blue status lights -Built in stand to allow modem to stand up easily which is something my surfboard always suffered from with coax being too stiff to allow it to stand vertically. -Setup and activation was super easy and quick (less than 5-10 minutes including waiting for comcast to recognize the modem) -Black in color. -Plenty of ventilation to prevent overheating problems and you barely notice the vents due to the design. CONS: None so far.

I needed a replacement modem for the one that Time Warner rented to us that needed to be reset around 3 times a day. So far this has been awsome, no resets needed yet, and much faster and reliable.

I upgraded from a dead model that is no longer supported by Comcast Xfinity to this amazing modem that brought my speed from 128Mbps up to 237Mbps. That was JUST with a modem upgrade connected wirelessly through WiFi through a Asus N router (imagine if you paired this with a AC router or better). I love it so far and would definitely buy it again
