Use reset button at the back.

if it is purchased - got to contact ISP to register the MAC address.

if it is provided by the ISP - have it replaced.

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.

My Motorola sb5101 won't come online how do I troubleshoot this? My cable connection is fine. When the modem boots up the green power light comes on and stays on followed by the receive light and the send...


These modems are very tricky. When this type modem goes into stand by modem that indicates that you do have a connection to your internet service provider. The reason you cant get online is because all internet access is disabled wile the modem is in standby. If you look closely there is a button located on the top of the modem. This is the stand by button. If you hit that button it should take the modem out of stand by mode and reestablish your connection to the internet.

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

My modem keeps going to standby mode


That is usually a problem with signal levels or the modem isn't set properlly. I don't know who your provider is but you should get hold of them and get them to fix it. They should send a tech out to check your signal. While they can check the modem remotely it does not provide them with the same information that a onsite check does. There is nothing you can check or change as a end user.

This can be signal levels, or signal quality (noise), or bad cableing and so on.

Cannot go to internet


As stated on your previous post asking this question:

"If the "Online" indicator is not on, then the modem does not have an internet connection. The only thing you can do is unplug the modem for 15 seconds and plug it back in. Wait 30 seconds for it to cycle and the lights should all come back...if the "Online" light still does not go on, then you need to contact your internet service provider."

There is really nothing else you can do!

Cable modem connection problem


Hi, First of all that particular modem is an End of Life modem (meaning it is no longer recieving updated firmware). But that still does not neccesarily mean that its your modem what you need to do when your modem cuts out is to note the leds on the front of your modem. If the modem gets stuck on either the 2nd light from the top or the third light then it is definitely a cable problem. Contact your cable co and tell the tech what lights were stuck blinking while you could not get online and he will know what that means. If you need some more help let me know, because I can explain more. good luck
