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.

Configuring TCP/IP

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.
Troubleshooting


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.

the ONLINE led must glow, the manual is clear about LED

3347w = wireless
LED DSL goes green solid but blinks as DSK trains and conn.
and
LED interenet solid green connnected. blinks for data and red = fail.
page 205 in 3000 series manual
google it read it..

online means internet, and fails for you
and means call the ISP any time the internet led goes dead or red
it is that simple. do it.

The Westell has several lights on the front that have various meanings

Power = When lit, this light indicates there's power to the router. It should be solid green.

Ethernet = When lit, this light indicates that the modem is communicating with your computer. This will be on only if you're using the Ethernet cable to connect the modem to your computer

Wireless = When lit, this light indicates that the wireless function of the Actiontec is working. This will only be lit if you're using the wireless function.

DSL = When lit, this light indicates the modem is speaking to the central office (phone company). When working, the light should be solid green.

Internet = When blinking, this light indicates that you're receiving information i.e., you're able to browse from site to site. This light will be blinking as you're receiving information.

This light pattern indacates that the modem can not establish a connection to your internet service provider (ISP). This is typically do to a signal related issue. To trouble shoot the problem you will need to connect the modem directly to the main cable line where it first enters into the home. You will know when the modem establishes a connection by the top 4 lights becoming solid green. If at any point all 4 top green lights start to blink in sequence than you will need to contact your internet service provider to "unwall the modem". Remember most internet service providers require you to register new modems on there network. So if you have not all ready completed that process you will most likely not have access. If you can not get a connection from the main line than there is a issue with either the modem or the signal coming into the home and you will need to contact your internet service provider.

I hope that information above has helped is some way.
If possible please rate this solution.

No because dsl light should be solid green light. You need to contact your ISP to check if there is a problem on the network.

hi rtoffler....

by the way, is the dsl light solid green or red???...and if it's red... the line connection from the server to your modem is doing good...however, you said that the internet light is red because you have not configured your modem properly.... i mean, you need to update the interface of your modem before you can go online....and whether the message said that you're connected to the network when you connect your XBox 360...the only assurance is when you can browse different websites and lets you go online...however, your pc should be in tri core so that it's compatible with your Xox 360 video game,kkk and so that you would not encounter problems and errors in the future,kkk....and by the way...the data light is always blinking esp if you're browsing websites, the faster it'll blink nd it can't go on a solid green light anyways...,,kkk....and i do hope i was able to configure a little to your concern now....and enjoy playing and downloading more and chanllenging and fun games with your Xbox 360k,,,,happy playing games, rtoffler!!!!! and happy new year by the way!!!!...:-D

Well, I understand that the modem is SS4100, which means ther are
5lights on it being, Power, Ethernet, DSL, Internet & Activity....
Note:The trouble shooting is done according to the Light Status on the modem.
1. No matter what the proble is, the first step is to Power Cycle the modem to eliminate the static on the modem(to switch it off and back on).
2. If the Power Light is anything other than a solid green, then the modem is fried(except the fact that the adapter is plugged and working).
3. If the Power is green and Ethernet is off, then check for the LAN cable at the back 
of the computer if its connected to the modem.(It turns green if connected properly)
4. If the DSL light is anything other than solid green, then call up the ISP tech's to ask why the intenet is not working.
(make sure the DSL cable is plugged firmly onto the back of the modem and the wall jack)
5. If the Power, Ethernet and the DSL is green and the internet is not, the open up the Modem page(type 192.168.0.1 in the address bar and enter for the modem page), and cross-check for the username and the password. Save the changes and your internet is working!!!
6.  The Activity light usually blinks green and it does't have much to do with the troubleshooting.
The above are the basic troubleshooting steps.
Hope it solves your problem......

Power Cycle the modem if the 4 lights do not go solid you would want to contact your cable provider to ensure signal is being received properly to modem.
