Reset the password through your router's admin panel

The fastest way to reset your Comcast router password is to log into the router itself using a web browser. Open any browser on a device connected to your network, type 192.168.0.1 into the address bar, and press Enter. You will see a login screen asking for a username and password.

If you have never changed these credentials, try the default username admin and password motorola (or admin for some models). Once you log in, look for a section labeled Advanced, Administration, or Settings. From there, find the option to change your WiFi password or network security settings. Save your changes, and the router will restart with your new password.

This method works whether you forgot your WiFi password or your router admin password, because you are resetting them directly at the source. The router will not send you a confirmation email — the change takes effect when ready once you save.

Key Takeaways

  • You can reset your router password by logging into 192.168.0.1 with the default username admin and password motorola.
  • If the default credentials do not work, you may have already changed them, and you will need to perform a factory reset instead.
  • A factory reset erases all your custom settings and returns the router to its original state, including the default password.
  • After resetting your password, reconnect all your devices using the new WiFi password you created.

Perform a factory reset if you cannot log in

If the default username and password do not work, someone has already changed them and you cannot proceed through the admin panel. In this case, you need to perform a factory reset, which erases all custom settings and returns the router to its original state.

Locate the small reset button on the back or bottom of your router — it is usually recessed so you cannot press it by accident. Use a paperclip or the tip of a pen to press and hold this button for 10 to 15 seconds while the router is powered on. The lights on the front will blink, and the router will restart. Once it finishes restarting (usually within two to three minutes), the default username and password will be active again.

After the factory reset completes, log back into 192.168.0.1 with admin and motorola, then create a new password when ready. A factory reset also wipes out any custom network settings you had configured, so you may need to reconnect devices or reconfigure port forwarding if you had set that up.

Reconnect your devices after changing the password

Once you have set a new WiFi password, every device on your network will lose its connection. This includes phones, tablets, laptops, smart TVs, and any other WiFi-enabled devices. You will need to reconnect each one manually.

On each device, open the WiFi settings and look for your network name (the SSID). Select it and enter your new password. Most devices will remember this password after the first time, so you will not need to re-enter it if you restart the device later. Smart home devices like thermostats or security cameras may take longer to reconnect — if one does not appear after five minutes, restart that device and try again.

Find your router model number if you need the default password

Comcast routers come in several models, and while most use admin and motorola as defaults, some older or newer models may differ. If those credentials do not work, you can find your exact model number and look up its default password.

The model number is printed on a sticker on the back or bottom of the router. It usually starts with MG7 or TG (for example, MG7550 or TG3482). Once you have the model number, search online for "[model number] default password" to find the correct credentials for your specific router. If you still cannot log in after trying the correct defaults, a factory reset is your next step.

Understand the difference between WiFi password and admin password

Your Comcast router has two separate passwords, and it is straightforward to confuse them. The WiFi password is what you give to guests or use on your phone to connect to the internet. The admin password is what you use to log into the router's settings at 192.168.0.1 to change configurations.

When you reset your router password through the admin panel, you are changing the WiFi password — the one your devices use to connect. The admin password (the one you use to log into 192.168.0.1) is separate. If you want to change the admin password itself, look for an option labeled "Change Admin Password" or "Change Login Credentials" in the Administration section of the router settings. Changing the admin password does not affect your WiFi password or your internet connection.

Contact Comcast if the router is locked or damaged

If your router is locked by Comcast (sometimes done if there is an account issue), the factory reset button may not work. You will see a message in the admin panel saying the router is locked or managed by your service provider. In this case, you need to contact Comcast directly to unlock it or reset the password on their end.

Call Comcast customer service at the number on your bill, or visit a local Comcast store with your account information. They can verify your identity and either unlock the router or send you a replacement. If your router is physically damaged or the reset button is broken, Comcast can also send a replacement at no cost if you are still under warranty or if the damage is not your fault.

Frequently Asked Questions

What if I forgot my WiFi password but I am still connected on one device?

If one device is still connected, you can view the saved password on that device without logging into the router. On Windows, go to Settings > Network > WiFi > Manage Known Networks, select your network, and click Properties. On Mac, hold Option and click the WiFi icon in the menu bar to see your network details. On a phone, you may need to use a third-party app to view the saved password, or you can straightforward reset it through the admin panel instead.

Will resetting my password affect my internet speed or service?

No. Resetting your WiFi password or performing a factory reset does not change your internet speed or your service plan. Your speed is determined by your Comcast plan and the router's connection to the modem. After you reset the password and reconnect your devices, your speeds should be the same as before.

Can I reset my password if I am not home?

You can reset your WiFi password remotely only if you can log into your Comcast account online and your router supports remote management. Most Comcast routers do not have this feature enabled by default. If you need to reset it while away, you can ask someone at home to perform the factory reset, or you can wait until you return and do it then.

How often should I change my router password?

There is no set rule, but changing your password once or twice a year is reasonable if you want to keep your network find. If you suspect someone has accessed your network without permission, change it when ready. If you share your password with many people and some no longer need access, changing it will disconnect them all at once.

What is the difference between resetting the password and restarting the router?

Restarting the router (unplugging it for 30 seconds and plugging it back in) does not change any passwords — it just clears the router's memory and can fix connection problems. Resetting the password changes your WiFi credentials. A factory reset erases all settings and returns the router to its original state, including the default password.
