How to Set Up a Motorola SURFboard Modem

SURFboard is a cable modem released by Motorola. It features surfing speeds of up to 160 MBPS and can be used on almost all major U.S. cable Internet service providers like Comcast, Time Warner, and many others. Like any other cable modems, the Motorola surfboard is very easy to set up and connect with your existing Internet service at home or at work.


Connect a coaxial cable to the modem.

Take the coaxial cable coming from the wall (similar to the coaxial cable connected to your TV for your cable service) and plug it to the coaxial port located behind the SURFboard modem. Make sure that you secure the connection firmly by screwing the coaxial cable onto the modem port.

Attach the SURFboard modem to your computer.

Take the Internet cable included in the modem package and plug it to the “Ethernet” port at the back of the SURFboard. Plug the other end of the Internet cable to the network (LAN) port at the back of your computer or laptop.

  • There’s going to be only one port on your computer where this cable can fit, so it won’t be hard to identify.

Connect the modem to a power source.

Get the power adapter and plug it to the power port located behind the SURFboard modem. Plug the other end of the adapter to an electrical outlet.

Turn on the modem.

Press the Standby/Power button at the top side of the SURFboard to switch it on. The status lights of the modem will start to blink.

Register and activate your modem (Motorola surfboard or any other modem) with an internet provider (comcast, time Warner, Verizon…

Wait for each light to go on, blink, and then get solid.

If you only have a blue flashing light for downstream (the light right below the power light) then you must contact your internet provider and register your modem with them.


  • Cable modems are used only for cable Internet services. SURFboard will not work with DSL/Broadband connections.
  • When you’re done using the modem, press the Standby button at the top or unplug it from the power outlet to conserve electricity.
  • The speed of your SURFboard cable modem will depend on your Internet service speed.
