Motorola Surfboard Cable Modem User Guide
The user guide for your Motorola Surfboard cable modem can mean the difference between knowing how to locate and diagnose problems with your connection or staring angrily into a maze of blinking lights.
The user guide provides information on properly setting up your cable modem, understanding the indicator lights and troubleshooting problems before you have to call your Internet Service Provider.Connecting Your Modem
Your Motorola Surfboard cable modem must be connected to your home's coaxial cable connection.
Connect the coaxial cable from your cable outlet into the "Input" jack on your cable modem.
If your modem is wireless, it will connect to any computers and wireless devices in your home through the wireless signal sent from the modem.
Wired Internet connections require that you use an Ethernet cable to connect your cable modem to any supported computers and devices.
Understanding the Front Panel
The front panel of your modem is your key to understanding the status of your cable modem.
The front panel features "Power," "Send," "Receive," "Online" and "Link" lights, each of which displays information about your modem.
The "Power" button will display a solid green light when operating normally and will turn off when there is a problem with the power supply.
The "Send" and "Receive" lights will transmit a solid green or blue color when data is being normally transmitted through your modem and will blink when it the modem is scanning for an upstream or downstream connection.
A solid green "Online" light indicates that you are connected to your Internet Service Provider, while no light indicates that the Internet connection in your home is experiencing problems.
A yellow "Link" light indicates that a computer is connected to your modem with an Ethernet connection while a blue light indicates that a high-speed Ethernet connection is being utilized through the modem.
The Transmission Control Protocol/Internet Protocol provides the basic foundation for establishing a local network and a connection to the Internet. The TCP/IP can be configured in the "Control Panel" of your Windows computer. Open the "Network and Sharing Center" from the control panel and double-click the "Manage network connections" option. Right-click the network connection displayed and select "Properties," then select Internet Protocol Version 4 and open the TCP/IP properties menu. Select "Obtain an IP address automatically" and "Obtain DNS Server address automatically" from the TCP/IP properties menu and click "Ok" to save your TCP/IP settings.
Many technical issues with your cable modem can be resolved by power cycling your modem and the computers and devices connected to it.
To power cycle your modem, unplug it from the power supply for 10 to 15 seconds and reconnect it to the power supply.
Restart all of your connected computers and devices while your modem is power cycling. Problems with the "Send" and "Receive" functions can be the result of a poor signal being sent to your cable modem. Tighten the coaxial cable connection to your modem and contact your internet service provider if problems persist.
