How to Factory Reset Comcast Modem?

Resetting your Comcast modem is generally a straightforward process, but the exact procedure to follow does depend on the type of modem you have. If you have access to your modem right now, take a look at it and try to identify the best strategy for resetting it completely. A soft reset, where you simply use the reset button on the modem, may not be enough to completely restore factory settings, so you will need to devise a plan that causes a full reset if that is what you need for your Comcast modem. Since a reset may change all of your settings and is usually impossible to undo, you should plan for how you will restore any settings you will need later. Keep in mind that resetting a modem may also change how your device behaves.

  • Factory Reset—A full reset to original factory settings. This allows you to restore your modem’s defaults in case something happens or you need to begin with new settings just like you are removing your modem right from the box as a brand-new device.
  • Soft Reset—A soft reset may not restore full factory settings, but it typically does restore some original settings or bring the modem back to some previous options.

In this article, we will share a few different approaches with you so you can choose a strategy that is most appropriate for your own device and service. By the end of the article, you will have several different ideas for how to reset your modem effectively, plus you will be able to restore settings as needed. You may not need to pay Comcast to reset your modem for you if you are able to do it yourself.

Do I Need a Reset?

  • Modem Not Working—If the modem is not working properly but otherwise appears to be fine, you should try resetting it to see if that resolves the problem.
  • Change to Settings—It is probably not necessary to reset after changing settings. In fact, resetting your modem may restore old settings and prevent your new changes from working properly. You may also, depending on the model, lose any firmware upgrades after a factory reset. A soft reset, however, may actually be necessary after changing settings on your modem. If you are not sure about that, you may want to ask your vendor or contact Comcast.
  • New Connection—If something about your connection or network is new, you may need to reset your modem. A soft or factory reset may be necessary. If you have specific questions or concerns, you may need to ask technical support.

Once you reset, be prepared to reset other devices in the network, too, if necessary. Keep in mind that many settings will need to be manually updated inside the system after a restart. You would need to update anything you need that differs from the factory settings your modem originally had. Resets can be used to resolve a lot of problems that can occur with modems, but some problems are beyond a reset’s ability to change. You should figure out which settings you want to keep and be sure to record them or remember them for later, so that after resetting your modem you can begin to use your preferred settings again if you plan to continue using the device.

1. Reasons for Resetting Your Modem

There are many reasons why people decide to try resetting their modems. If you are having problems successfully using your modem to connect to the Internet, interact with your other devices or provide service, you may decide to try resetting your modem so you can reconnect it. Preparing to turn in your modem if you move and change services or stop your Comcast service for some reason can also mean you need to reset your modem.

If you decide to upgrade to a new device and recycle your own one, this could be another motive for resetting. If you have already tried to reset the device on your own and have yet to succeed, learning about the process can help. It may also save you money if you are able to avoid a service visit fee, for instance.

2. Voice Modem

A voice modem from Comcast typically has a reset button, so this provides an easy way to perform a factory reset of your device. To reset your modem, start by finding a pen or another thin object you can use to press the button. Paper clips are also great for pressing reset buttons—all you have to do is carefully straighten out and unhook the paper clip so it becomes a point you can use to push the button.

Look for a marked reset button on the front or back of the device and prepare to press it with your thin object. Try pressing the button. If that does not work, you may need to reset the modem more than once or try resetting with the button and a combination of other techniques, such as power cycling.

After the reset, you may need to restart any computer you have connected to the system, depending on how your voice network is configured. Be prepared to reset other devices and connections, if necessary.

3. Reset Buttons

With other types of modems, you may or may not need an object to press the reset button. Either way, try pressing the button for five seconds and seeing if that successfully resets the modem. You should notice a difference fairly quickly. If not, you may need more than one reset or you may need to try other methods. These buttons are always clearly labeled, which should make it much easier to identify the reset feature and begin using it.

Keep in mind that you may need to wait several minutes for your modem to reset. After the reset, original settings should be restored again.

4. Power Cycling

Power cycling basically shuts off power to the modem to force a reset. Try unplugging the modem from electricity and keeping it unplugged for a few minutes. Usually, this will provoke some type of hard reset and restore the modem to factory settings. You may need to try this technique multiple times and combine it with other strategies, such as using the reset button.

5. Other Ideas

If all else fails, you may need help from technical support for your modem or from Comcast. There may be a hardware, firmware or software problem preventing you from successfully resetting your modem.

Be sure to let the technician know exactly what you have already tried so there is no duplication of effort. Record each step so it is easier to retrace what was already done as you tried to reset your modem and were unsuccessful. If you have any other questions about the process, be sure to record them for when you talk to Comcast or when you contact support for help. This can help you streamline the process and get your modem working properly again.
