Works with ANY Cable Internet Provider

If you have cable internet through Comcast, Time Warner, Charter, Cox or any other major cable internet provider this modem WILL work for you. NOTE: Verizon FiOS and AT&T U-verse are NOT cable providers and will not work with this modem. The cable modems most of these providers give their customers are trash. They don’t work well and they’re certainly not fully optimized to take advantage of ultra high-speed connections. Owning your own cable modem will save you on your monthly bill and give you the peace of mind knowing that you are using a high quality device and not a dime-a-dozen piece of junk.


The greatest benefit of the DOCSIS 3.0 standard is the ability to use channel bonding. This means your cable modem is able to merge live streams of data on the fly. This allows you to take advantage of additional bandwidth for high bandwidth applications like video streaming. It also provides extensive security and network management features not found in most older devices.

* Actual speeds will vary, and are often less than the maximum possible. Data transmission speed is approximate and depends on the configuration and capacity of your network, as well as the amount of traffic on the network.

** Actual data throughput will be less due to physical layer overhead (error correction coding, burst preamble, and guard interval). Certain features may not be activated by your service provider, and/or their network settings may limit the feature’s functionality. Additionally, certain features may require a subscription. Contact your service provider for details. All features, functionality, and other product specifications are subject to change without notice or obligation. DOCSIS 3.0 modem capabilities are dependant on the services available through the CMTS. Please verify with your CMTS vendor their specific DOCSIS 3.0 implementation roadmap.
