Access your router's settings through the Xfinity app or web browser

The fastest way to change your Comcast router password is through the Xfinity app on your phone or tablet. Open the app, tap the menu icon, select "Internet," then "Wifi Settings," and look for the option to change your network password. The app walks you through each step and saves the new password automatically.

If you prefer a computer, you can also log into your router's settings page directly. Open any web browser and type 10.0.0.1 into the address bar, then press Enter. You will see a login screen asking for a username and password. The default username is admin and the default password is motorola (or sometimes motorola123, depending on your router model). Once you are logged in, look for a section labeled "Wifi," "Wireless," or "Network Settings."

Key Takeaways

  • The Xfinity app is the easiest method because it handles the login automatically and shows you each step on screen.
  • If you use a web browser, type 10.0.0.1 into the address bar and log in with the username admin and password motorola.
  • Your new password must be at least 8 characters long and can include letters, numbers, and symbols.
  • After you change the password, all devices connected to your wifi will disconnect and need to reconnect using the new password.
  • If you forget the new password, you can reset the router to factory settings by holding the reset button for 10 seconds, but this erases all your custom settings.

Create a strong password that you can remember

Comcast requires your new wifi password to be at least 8 characters long. You can use uppercase letters, lowercase letters, numbers, and symbols like exclamation marks or hyphens. A password like BlueSky#2024 or Garden-Rain-42 is strong enough to protect your network from casual attempts to connect without permission.

Avoid using your name, address, or birthdate, since these are straightforward to guess. Also avoid straightforward patterns like "12345678" or "password." Write your new password down in a safe place — a notebook in a drawer, not a sticky note on your monitor — so you can refer to it if you forget it later.

Reconnect your devices after changing the password

Once you save the new password in your router settings, your wifi network will stay online, but every device currently connected will disconnect within a few seconds. This includes phones, tablets, laptops, smart TVs, and smart home devices. You will need to reconnect each one manually.

On your phone or tablet, go to Settings, find your wifi network name in the list of available networks, tap it, and enter your new password. On a computer, do the same through your network settings. Smart devices like Alexa speakers or smart thermostats may take longer to reconnect — some require you to open their companion app and re-enter the password there. If a device does not reconnect after a few minutes, restart it by unplugging it for 30 seconds, then plugging it back in.

Log in with the web browser if the app does not work

If the Xfinity app is not installed on your phone or if you prefer not to use it, the web browser method works just as well. Type 10.0.0.1 into your browser's address bar — this is your router's local IP address, not a website. You should see a login page within a few seconds.

If the page does not load, make sure you are connected to your Comcast wifi network (not a different network) and that you typed the address correctly. If you still see nothing after 30 seconds, restart your router by unplugging it for 10 seconds, waiting for all the lights to come back on, and trying again.

Find the wifi password section in your router settings

After you log in with the username admin and your default password, look for a menu on the left side or top of the page. Different router models label this section differently — it might say "Wifi," "Wireless," "Network," or "Advanced." Once you find it, you should see a field that says "Network Name" (this is your wifi name, also called the SSID) and another field that says "Password," "Passphrase," or "Network Key."

Click in the password field, delete the current password, and type your new one. Make sure you type it exactly as you want it — uppercase and lowercase letters matter. Then look for a button labeled "Save," "explore," or "Submit" and click it. The router will process the change, which usually takes 30 to 60 seconds.

Reset your router to factory settings if you are locked out

If you forget your new password and cannot log into the router settings page, you can reset the router to its factory defaults. This erases all your custom settings, including the password you just created, and returns everything to how it was when you first got the router from Comcast.

To reset, locate the small reset button on the back or bottom of the router — it is usually recessed so you cannot press it by accident. Use a paperclip or the tip of a pen to hold down the reset button for 10 full seconds while the router is powered on. The lights on the front will blink rapidly, and the router will restart. Once all the lights stop blinking and return to normal, the router is reset. You can now log in again using the default username admin and default password motorola, and you can set a new password from there.

Frequently Asked Questions

Can I change my router password from my phone without the Xfinity app?

Yes. Open any web browser on your phone, type 10.0.0.1 into the address bar, and log in with the username admin and password motorola. The process is the same as on a computer, though the screen may look slightly different because it is sized for a smaller display.

What is the difference between my wifi password and my Xfinity account password?

Your wifi password protects your home network and is what guests need to connect to your internet. Your Xfinity account password protects your billing and service information on Comcast's website. Changing one does not affect the other. You can change your account password separately through the Xfinity website or app under Account Settings.

Do I need to tell Comcast when I change my router password?

No. Your router password is yours to manage. Comcast does not need to know what it is. You only need to contact Comcast if your internet stops working entirely or if you cannot connect to the router at all after the change.

Why did my devices disconnect when I changed the password?

When you change the wifi password, the router broadcasts the new password when ready. Devices that were connected with the old password no longer match, so they disconnect automatically. This is a security feature — it prevents someone who knew your old password from staying connected without your knowledge.

Can I change my router password back to what it was before?

Yes. Log back into your router settings at 10.0.0.1, find the password field, and type in your old password. Save the change, and your devices will reconnect using the old password. However, if you have already reset the router to factory settings, you will need to set up a new password from scratch.
