Linksys DOCSIS 3.0 8x4 Cable Modem Certified with Comcast Xfinity, Time Warner Cable, Charter, Cox, Cablevision, and more (CM3008) (Renewed)

Bye bye $10 monthly modem fee, saved me 33% on my monthly bill, will pay for itself in two billing cycles! Works great with Cablevision, Optimum Online. I have the cheapest plan (Optimum 25, 20Mb download, 5Mb upload). All I had to do to activate the modem is call the company and give them to modem model and MAC number and they sent me a shipping label to return the old one. I checked my internet speed with speedtest.net and the test that shows up when you google "internet speed test" and the first result is a speed test before and after replacing the modem. My results were around 20Mb download and 5Mb upload before the upgrade. After the upgrade, when I tested the next day in the morning when there is less traffic, my results were a little better. I got around 28Mb download and 5Mb upload with the new modem. This is the service I get in north Jersey. I will be getting a second one for my mom. Best 18 bucks you can spend if you rent a modem from you internet provider! Another positive about this modem is it's small size.

Was on the phone with Comcast to activate, took 5 minutes - plugged this thing in and it works great. I'm getting my full speed, no issue at all and this device is the size of a portable hard drive or a large cell phone which is pretty amazing - but the sweetest part: it will pay itself in about 2 months (!!) by saving the rental costs of a Comcast router. Note that you do have to have a router for wifi - this device does NOT provide wifi support, it only gets the cable signal and converts it to Ethernet so you can connect your router to it. Also, connecting the router is super easy! this device's address is 192.168.100.1 by default (factory settings) so just make sure you configure your router so that the gateway is 192.168.100.1 and you're basically done.

This is one compact modem, which is what I wanted. Unfortunately, it was a refurbished item and I fear I now know the defect... the connection to hardwire was inoperable! After repeatedly trying to get the eero mesh wifi router unit to connect and set up, the eero rep talked me into considering the modem as the issue. I bought another modem and sure enough, the eero worked fine. It was the bad connector I was hardwiring the eero to that was causing my frustration. Perhaps a new one would have worked. This thing is sooo small and compact, I truly wanted it to work out. Just don't opt for a refurbished one.

The modem works perfectly! I am getting well over my paid speed for Comcast internet. It's tough to believe because it is a tiny little modem, but it works great. My only complaint is that it was shipped in a box with only one piece of tape to hold it closed which was broken when it arrived, so it easily could have come open and I would have lost some of the paperwork or something. Other than that, everything was great!

For such a little modem it works great! We needed a new modem after our internet provider upped the speeds and our old 2.0 modem wasn't going to work. We searched Amazon and found this one for a good cheap price. Works like a charm! We have it in our dining room, our house is an open floor plan so so connection easily reaches everywhere in the home. Would definitely recommend buying and placing in the middle most area of the house so you can get maximum connection. But even in our basement the internet works great! At first we didn't think it would work well because it was "cheap" and were tempted to buy a more expensive one. But this works just fine!

This modem used to work with Xfinity but not anymore. To be clear it's really not Linksys fault that it no longer works with Xfinity but if they had made it possible for the user, and not the cable provider, to manually change firmware then this wouldn't have been a problem.Xfinity pushed out a firmware update for this modem, 1.0.00.013, and it includes a bad configuration file that breaks it. Now the modem only provides an intermittent connection that is completely unreliable. It is impossible for the user to change the firmware version and even though the Xfinity engineers have known about the problem for a while they do nothing about it.
