Question about Motorola Computers & Internet

My internet modem SB5101 keeps cutting out. In a days time it goes from normal (all green lights steady) to not normal with one or more lights blinking, and I can't connect to the internet. What I want to know, how do I know if my modem is defective?

    I have already checked with my internet provider. They find nothing wrong with my connection.

    Is there any way of knowing if the modem is bad or may have a problem

  • artvr Oct 11, 2008

    I do not understand how to do what you're saying. Give me more details as to where I enter the number192.168.1.1, and where I enter my user name, etc.

Hi,

Your intermittent connectivity while using a Motorola SURFboard SB5101 might be related to how said modem is connected to your computer:

  • Ethernet
  • USB.
In either instances, Windows could turn off the connection after inactivity automatically. Pls try to disable the "Allow the computer to turn off..." in the Power Management tab of the USB Root Hub Properties in your Device Manager. Do the same for your networking card.

Other possibilities include:
  • lease expiration of the assigned IP add from the DHCP. You could try assigning static IP add;
  • erring or inadvertently pressed stand-by button that provides hassle-free security by disengaging from the PC without disconnecting from the cable network.
Have you tried the online diagnostics page?

Should none of the above address your issue, then either a firmware update or a unit replacement would have to be considered. Other consideration would be how familiar you are with networking. With this mind, you may have to reference closely the step by step as detailed in the manual or seek the services of a qualified professional.

Hope that this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

When you say that the green light starts blinking, you need to check that whether it is the "Link light" which is blinking. If it is than it is quite possible to have a fault in the Cable line.

Also most of the times the ISP would not agree that there is an issue at there end, you will have to call them a few times to make them agree on the same.

Also i am sure that you must have tried powercycle on the modem, IF NOT than you just have to turn it off for about 20 minutes and than turn it back ON.

Now if you really think that it is the modem, you may do a hard reset on the modem.
To Reset you need to find the reset button on the modem(Usually a pin hole button at the back of the modem, you need to press and hole it for 10 seconds).

Note: If you do a hard reset, if there are any settings saved on your modem for the ISP, they will be lost and you might have to call the ISP for guiding you to set u the internet again(10% chance).

I am sure that this would help. If you had got the modem as well from the ISP , than keep bugging them and they will replace it if required...

Hi,

See what you can do is just login to your modem by typing this into your browser 192.168.1.1 and enter the username as admin and password as password or admin.
Next just find a RESET TO FACTORY SETTINGS option there and click on it.IF you still have any difficulties connecting then it is the modem and you will have to get a new one.

Hi, It may not be the problem with your modem. Try calling your ISP (Internet Service Provider) and tell them that connection if often diconnected. 

You could check your modem by connecting w/ someone else's cable input and see if it works.

  • Karthik P Oct 11, 2008

    Blinking light means that the modem is attempting to connect.
    If ISP does not find any problem with connection, modem might be defective. So please check with another cable or ISP to confirm.

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.

My motorola SB5101 cable modem is connected properly. The power light is green but the receive light is keep on blinking other lights was turn off (send, etc.). Does my modem has a problem?

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.

Motorola cable modem sb5101 the receive light blink an the same as the send light


If you are able to access the internet this is a normal operating status. These lights are just letting you know there is activity present with the modem and the modem is sending and receiving information with your provider.

My Motorola Sb5101 modem will not let me access the internet, the send light constantly flashes and i can't attain any internet connection.


If you have the following lights :
Power light - on
Receive light - flashing
Send light - flashing
Online light - off
PC/Activity - on
Standby - off
Then your Network Access is OFF - modem is successfuly registered but Network Access Control is disabled via DOCSIS configuration file.

Call your internet service provider....

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.
