Re: How do I restore this cable modem back to factory...

One sure way to reset the modem back to factory settings, is to get on a computer that is connected to it, could be anyone. From there, you would open the internet, and then type in the address bar: "". If you did not mess with this stuff eailier or ever, then the user name is blank, and the password is admin, by defualt. You would then go to security, And you will see two buttons that saids "yes", or "no" to restoring back the factory defaults, click, "yes". And then click "Apply" at the bottom of the page, it should take about a good minute to apply and restore it back to the factory defaults. And that is how you restore it back to the factory defaults.

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.

I forgot my password

Reset the modem by removing the power cable from the back of the modem for a full 30 seconds and plugging it back in.

This is sometimes referred to as "power cycling" the modem, and is a good way of clearing network timeouts and other problems that can appear on modems that have been running continuously for some time.

Reset the modem by unplugging the power cord from the electrical outlet or surge protector into which it is plugged.

This is a good alternative to removing the power cord from the back of the modem if it is difficult to get to the modem because of its physical location. Count the full 30 seconds and plug the modem back in to complete the reset.

Reset the modem by pressing the reset button the back of the modem.

The button itself is recessed into a hole to prevent accidental resetting, so you will need a pen or some similar thin utensil that can fit inside the hole.

Press the pen into the hole until you feel the button depress and then let go.

This is sometimes called a "hard reset" or "hard reboot," as this will restore the modem to its factory default settings

Hope this helps

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.

How i can re-set factory default for Thomson TG585. i can't set up a user id and password for my net connection.

You can reset Thomson TG585 by pressing the reset button located at the back of the modem for few seconds while the modem is power on. The LEDs at the front would blink and the modem will restart with factory defaults setting.

Let me know if any further clarification/ assistance is required.

Good Luck!
Appreciate generously, if the solution could have been of any help!

Cant login to my sbg900, using admin for login but not recognising password

Try resetting the router. You can find a small hole with a button inside it at the back of the modem. Use a pin or a paperclip to press it for 5-10 seconds so that it will be restored to the factory settings.

Hope this helps! :D

Internet shuts when i download!

is your PC on DHCP or static?
perhaps try putting PC on static and see if this helps.
perhaps try reseting router to factory default and try again.
Looks like for some reason your PC is trying to pick new address every time you download which could be coincidence.

But try with static first and restore with factory default.

Let me know how it goes.
