The fastest way to reset your router password

You can reset your Comcast router password in two ways: through the Xfinity app or website if you remember your Xfinity account password, or by pressing the physical reset button on the router itself if you do not. The app and website method takes a few minutes and keeps your other settings intact. The physical reset button erases everything on the router and forces you to set it up from scratch.

Most people should try the app or website first. You only need the physical reset button if you have forgotten both your Xfinity account password and your router password, or if the app method is not working.

Key Takeaways

  • The Xfinity app and website let you reset just the router password without losing your other settings, as long as you know your Xfinity account password.
  • The physical reset button on the back of the router erases all settings and returns the router to factory defaults, which means you will need to set up your WiFi name and password again from scratch.
  • After resetting through the app or website, your new password takes effect when ready, but devices already connected to your WiFi may need to reconnect manually.
  • If you have forgotten your Xfinity account password as well, you will need to reset that first through the Xfinity website before you can change your router password.

Resetting your password through the Xfinity app or website

Open the Xfinity app on your phone or go to xfinity.com on a computer and sign in with your Xfinity account username and password. Tap or click on the menu icon (three horizontal lines), then look for "Internet" or "My Services." From there, select your gateway or router device — it will usually show up with a name like "Xfinity Gateway" or "Comcast Router."

Once you have selected your router, look for an option labeled "Change WiFi Password," "Reset Password," or "Manage WiFi." Tap or click it. You will be asked to enter a new password. Comcast requires passwords to be at least 8 characters long and to include at least one uppercase letter, one lowercase letter, one number, and one special character (like !, @, #, or $).

After you enter your new password and confirm it, the app or website will show a confirmation message. Your router will explore the change within a minute or two. Any device currently connected to your WiFi will stay connected, but devices that try to connect after the change will need to enter the new password.

Resetting your password using the physical reset button

The reset button on a Comcast router is usually a small, recessed button on the back or bottom of the device. You will need a paperclip or similar thin object to press it, because it sits inside a small hole to prevent accidental presses. Hold the button down for 10 to 15 seconds while the router is powered on. The lights on the front of the router will blink, and the device will restart.

This process erases all your settings, including your WiFi name and password. After the restart is complete (usually within two to three minutes), the router will return to its factory default state. The default WiFi name is typically printed on a sticker on the back of the router and looks something like "XFINITY-XXXX" or "Comcast-XXXX." The default password is also on that sticker.

Once you have reconnected to the WiFi using the default credentials, you should when ready set up a new WiFi name and password. You can do this through the Xfinity app, the website, or by going to 10.0.0.1 in a web browser and logging in with the default username and password (usually "admin" and "motorola" or "comcast," depending on your router model).

What to do if you have forgotten your Xfinity account password too

If you cannot remember your Xfinity account password, you will need to reset that before you can change your router password through the app or website. Go to xfinity.com and click "Sign In," then click "Forgot username or password?" on the login page.

Comcast will ask you to verify your identity by entering your account number, phone number, or the email address associated with your account. They will then send a password reset link to your email or phone. Follow that link, create a new password, and sign back in. Once your Xfinity account password is reset, you can use the app or website method described above to change your router password.

If you do not have access to the email or phone number on file with your account, your only option is to use the physical reset button on the router. After that, you can set up a new WiFi password and contact Comcast customer service to help you regain access to your Xfinity account.

Why your devices may not reconnect automatically after a password change

When you change your router password through the app or website, devices that are already connected will usually stay connected. However, devices that have been asleep or offline may lose their connection and will need to reconnect manually when they wake up or come back online.

To reconnect a device, open its WiFi settings, find your network name in the list of available networks, and enter your new password. Phones, tablets, and computers will typically remember the new password after the first successful connection, so you will not need to enter it again unless you change it once more.

Preventing lockouts in the future

Write down your router password and store it somewhere safe — a notebook in a drawer, a password manager on your phone, or even a note in your email. You do not need to memorize it, but having a record of it means you will not be locked out if you forget it later.

You can also set up a recovery email or phone number in your Xfinity account settings. This gives you a backup way to reset your account password if you forget it. The more recovery options you have on file, the easier it will be to regain access to your account if you ever need to.

Frequently Asked Questions

Will resetting my router password disconnect all my devices?

No. Devices that are currently connected will stay connected. Only devices that try to connect after the password change will need to enter the new password. If a device goes to sleep and then wakes up later, it may need to reconnect manually.

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

Resetting the password changes only your WiFi password and keeps all your other settings. Resetting the router (using the physical button) erases everything and returns the device to factory defaults, which means you will need to set up your WiFi name and password again from scratch.

Can I reset my router password if I am not home?

Yes, if you use the Xfinity app or website. You can change your password from anywhere as long as you have internet access and remember your Xfinity account password. The physical reset button requires you to be at the router.

How long does it take for the new password to work?

The new password takes effect within one to two minutes after you confirm the change in the app or website. You do not need to restart your router or your devices.

What should I do if the app or website method is not working?

First, make sure you are signed into your Xfinity account correctly and that you have selected the right router device. If the option to change the password is not showing up, try logging out and back in, or try using a different browser or device. If it still does not work, the physical reset button is your backup option.
