Question about Arris SURFboard SB5120 Modem

1 Answer

Every morning, I find the Surfboard with only the power and PC light lit. All other lights are off and I have no internet connection. I have to unplug and replug the modem (twice) every day to regain all lights and an internet connection. The reason I have to unplug and replug twice, is that the first time, the same two lights come back on and it just sits there. The second time, it cycles through start up and regains connection. It it simply time for a new modem??

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.

I want to plug in another wireless router into my surfboard modem and have the wireless router work as well as the surfboard. Is there a way to do this successfully?


Yes this is possiable. First you need to unplug the power to the Motorola and the new router. Second connect the ethernet cable from the Motorola to the internet port on your second router. This port may be colored in yellow, marked as modem, or the ethernet port by its self. Third connect a ethernet cable from the new router to a desktop or laptop this is only to configure the new router. Next power on the Motorola and wait for the online light to become solid. Then plug in the power to the new router. Give the router about two minutes to obtain ip address from the motorola then try to get on the internet with the pc connected with the ethernet cable. Now you can run the new router setup cd on the wired pc to setup router. Once completed remove ethernet cable to the pc and connect to either network you have and you are good to go. Any questions just ask.

My motorola SURFboard SB5101 has a on power light, a blinking recieve light, and an on PC/Activity light, with the other lights off. what is wrong with it?


The light pattern you have described indicates 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 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 your modem on there network. So if you have not all ready completed that process you will most likely not have access.

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

Cannot set up Motorola Surfboard SB5120 modem


This usually means something is not correct with your incoming signal. If your cable wire into the modem is being run off an amplifier in the wall this could be effecting your service. If the signal is too strong the modem won't be able to communicate for internet.

You could check the incoming wire to see if it is running off an amplifier. If it is you would need to run a new line that is not on the amplifier. I would recommend comcast coming out to check the signal frequency and make the necessary adjustments.

Wireless router on but not working


Who is your ISP? I belive what you have is a modem router. If the interney light is not lit then it only mean that the actiontec is bridged and you need to use a dialer on your pc to connect to your ISP. If the internet light is lit, no need for a dialer just connect it straight to your pc and check your internet.
