Question about Arris SB5100 SURFboard DOCSIS 2.0 Cable Modem (50120900100)

1 Answer

Can't connect to the internet

I registered my cable modem (Motorola SurfBoard 5100) with my ISP this morning and after I connected the power supply, cable and ethernet cable, I still have no connectivity. The power light is on, but receiving is blinking. My ISP said that I need to set up an appointment for a service call, but I was trying to avoid that and get it hooked up today if possible. Please help.

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.

Motorola surfboard 5100 garden walled error


Sounds like your modem is in a provisional state. Walled garden is simply a tool to provision a modem..... a way that a cable or ADSL company uses to verify that the equipment is associated with a paying customer. Call your ISP if you are unable to access anything past that page via a browser. Chances are your provisioning record is lost, your modem has changed, there are too many devices connected directly to the modem, or there are other account issues such as nonpay status.

Before you call...
Check your modem connections, most companies will not allow two IP addresses to be issued to one piece of equipment (modem) without an extra fee, some companies will not allow two devices to be connected to a modem at all. If you have a device connected USB to the modem and another device connected through the ethernet port...disconnect one. I suggest going Ethernet and using a router if you wish to have more than one device connected to your modem.

Make sure the modem that worked yesterday is the one you are using today. If you've recently replaced your modem, you may need to call your cable company to register the new modem. One modem = one instance of service.

Check your bill due date. If your bill is past due, you may need to satisfy the past due balance before being allowed past the walled garden.

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.

Online light blinkin in motorola sb4200


1- Disconnect the power at the back of the modem.
2- Disconnect the internet cable at the back of the modem (the cable from the wall to the modem).
3- Wait at least 2 minutes.
4- Connect the internet cable back.
5- Connect the power cable back.
6- The lights on the front of the modem should start turning on one at a time; the top one first, the second one next...

If the on-line light still blinks, you might want to repeat the steps above after shutting down your computer. Turn on your computer if the on line light is OK (not blinking).

If all fails, call your internet service provider (ISP) to see if the service itself is down for maintenance, or if there is a problem with high-speed internet in your area.

If you have a router, you might want to power it off before trying the steps above. Turn it back on when the on line light is OK.

Usually, I call my neighbor who has the same ISP to see if their internet is down, before I call the ISP company.

Hope that helps.

I have a motorola SB5120 modem but no disc for it.How can I make it work?


With this type of modem no type of software will be required to establish a connection to your computer or router. However the modem will still need to be registered with your internet service provider. If you do not have the software to complete the registration process you will need to contact your ISP. The good news is that the registration of the modem should not take more than a few minutes and can be performed over the phone. After the registration has been completed connect the modem to your computer via a Ethernet cable. You may need to perform a hard reset of the modem at this time. To do this turn off your computer and unplug the power cable from your modem. Wait 2 minutes and reconnect the modems power cable. Give the modem another 2 to 5 minutes to reestablish the connection to your ISP. Power back on the computer and you should have internet access.

I hope the information above has helped in some way.

Cant connect to xbox live need an ip address how do i get one


When the SurfBoard modem is powered up and connects to the internet on the WAN interface, it automatically gets an IP address from your ISP. When another machine is powered up and is connected to the modem via a USB cable, it is automatically using the WAN IP address to communicate with the world. If it is connected via the Ethernet connection, the modem automatically issues it its own IP address for use on the internal network via DHCP. The modem's internal Ethernet connection is 192.168.0.1. The next machine powered on will normally get an IP address of 192.168.0.2.

SB5101 Motorola Modem Disconnects Randomly


If all the lights go out I would assume you mean the power light as well. Couple of things I would look at:

Has your ISP replaced the modem including the power adapter?
Has your ISP verified there is no short on the incoming data cable? You could try to wiggle the incoming data cable to see if the lights go out. I would do the same on the power cable.

If it's not a mechanical fault (cables), verify that you have the correct and current drivers for your modem and operating system.

Good luck and thanks for using FixYa.
