Welcome to Approved Cable Modems.  Please select an internet provider below to see the approved modems we've listed for that provider.  If you don't see the device you're looking for or your cable provider is not listed, please email our Support Center Team and we'll get back to you. We have thousands of additional modems not listed on the site.

Cable Modems require an extended testing period while connected to a Cable Modem Termination System (CMTS). Don't be fooled by a modem that appears functional when it's connected for a short time.  Many modems while online will intermittently disconnect from the cable system or drop WiFi connections. Our cable modems are analyzed with our state of the art Cable Modem Diagnostic System for a minimum of 8 hours where cable system connectivity, wireless transmission rates, and signal strength are monitored and recorded. Ask any other online seller of refurbished cable modems if their devices are subjected to this level of scrutiny, AND ask them to prove it!  We can, we stand by our product 100%.

 
Please Note: Not all cable modems are compatible with all cable providers.  Please contact your provider to ensure the model you want is compatible with their system before you purchase. All cable modems are refurbished and tested unless stated otherwise.
