How to reset password for motorola surfboard cable modem sb6141

There is no password on the SB6141.
There are no user configurable options. Any configuration is changed through communication with the CMTS.

When you access the modem ( all you can do is monitor the signal quality and certain log entries.

NOTE: the "configuration" page allows you to reset the factory defaults and to restart the modem. IF you reset factory defaults this note applies:

Resetting the cable modem to its factory default configuration will remove all stored parameters learned by the cable modem during prior initializations. The process to get back online from a factory default condition could take from 5 to 30 minutes. Please reference the cable modem User Guide for details on the power up sequence.

Every 5 minutes or so the modem suddenly resets. can this be fixed?

I would do a factory reset on the modem, there should be a red or white reset button of the back on it, Just push the button down with a paper clip or something and hold it down for 10 seconds and release. This should completely reset the modem to factory settings, if it is a internal hardware problem then the issue is should be handled by the manufacture i dont recommend opening a cable modem. Changing the power cable is were i would start if the reset fails.
hope this helps, feel free to reply with any questions.

I'm having trouble connecting my emachine to a cable modem.

Turn off the computer before you begin making connections. Make sure the cable modem is up and running with your service before you attempt to make the computer connection.

  • 2 Connect the coaxial cable from the wall outlet into the back of the cable modem where it is marked "Cable" and has the male coaxial connection. Use an extension coaxial cable if necessary to reach the modem.
  • 3 Connect the CAT 5 networking cable from the cable modem where it is marked "PC" (or something similar) and connect the other end into the back of your computer where the networking card is. These connections are RJ-45 connections that look like oversized telephone jacks. If you also have telephone service through your cable provider, you will want to connect the telephone line into the port on the back of the cable modem marked "Telephone."
  • 4 Connect the power cord into the back of the cable modem and plug it into a power strip with power surge protection. The modem should power on by itself once it is plugged in. It will cycle through a power on self test and then make the connection to your cable Internet provider. Once the lights indicating power and cable are green, you are ready for Step 5. It could take several minutes for the modem to connect to your service provider.
  • 5 Turn on the computer and test out your Internet connection. Should your computer still have a problem connecting to the web you may need to reset your cable modem. You will find a small recessed button the size of the head of a ballpoint pen either on the back or front of the modem. This button will be marked "Reset." Pushing it once will allow the modem to reboot and reset all its connections. Turn off the computer before resetting the modem to allow the computer to flush all the networking connections out of its memory as well.

  • If the power goes out and your connection is not restored when it comes back on, always reboot the devices in this order: cable modem first, computer second. Keep the cable modem where it can get proper ventilation. Call your cable Internet provider if you get frequent interruptions to your cable Internet service and rebooting the modem does not solve the problem.

    Of a sudden, my wireless TV won't stream netflix videos without buffering every 30 seconds -- a new problem. Is it possible to reset the modem? What is the likely problem?

    Yes, but you may be having a problem with your internet provider, not your modem.

    1) Yes, you can do a soft reset of your cable modem, just pull the power plug, and then plug in. Suggesting you leave the power cord out for 30 seconds. This will do a soft reset of your cable modem, and will not hurt any settings. No worries.

    2) You can do a "hard reset" but this is a bit dangerous. If you have any "custom" settings in your router, passwords, or configuration, it will be lost. If you do need (want) to do this, you will first want to go into the cable modem, and "save" your current configuration. At least make "note" of what the configuration is on a piece of paper, for each tab. Also, if you do this, your cable modem will go to its default settings and password. So, suggesting taht you DO NOT do a hard reset without prep. To do a hard reset, on the back of the cable modem is a red button, push and hold for 30 seconds. (Again suggesting, you do not do this without prep.)

    That will let you do a reset....

    However, I'm thinking that your buffering may be the result of an issue on your computer or your ISP. Tell us more about your configuration. dw

    I try 2 plug my modem up 2 my ps3 but the ip address timed out wat do i do

    After you have the Ethernet cable from your modem plugged into your PS3 press and hold the reset button on the back of the modem for about 5-10 seconds. This will reset the modem so that it will recognize the connect to your PS3. Once your done using your PS3 and reconnect the Ethernet cable back to your computer you will have to reset the modem again. Any time you move the Ethernet cable from one device to another you need to reset it after you have the cable connected to what ever device you want to get online with at that time. If you do not want to keep resetting your modem all the time a router will allow for you to have more then one device online at a time. The router will connect to your modem and then your devices will connect to your router.

    How to reset moorola modem sb1520 surfboard

    hi, to reset the modem follow these steps.

    step 1 : Turn the Motorola Surfboard SB5120 Cable Modem so that the back of it is accessible to you. There's no need to disconnect any of the cables.

    step 2 : Find the "Reset" button on the modem. It's a small recessed button located between the USB port and the cable outlet.

    step 3: Use a pointed instrument to push the button. Hold it for 10 to15 seconds to allow time for the modem's indicator lights to go off.

    step 4 : Release the Reset button. The lights will gradually begin to come on as the modem connects to the communications channels between the cable provider, the computer and the Internet provider. When all the connections are made, the lights will stablize.

    step 5 : Release the Reset button. The lights will gradually begin to come on as the modem connects to the communications channels between the cable provider, the computer and the Internet provider. When all the connections are made, the lights will stablize.

    Re-starting a ARRIS modem after a loss of power

    You can try doing a "Hard reset" on the modem but it looks like you've tried most combinations. To do the hard reset: - unplug the coax cable from the back of the modem - Push and hold the "reset" button in for 15 seconds - Allow the modem 30 seconds to reinitialize and then plug the coax cable back in. Within 10minutes you should have activity back. If not, the modem needs to be replaced. I know you may have tried something similar to this but I'm hoping this may help.
