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

To change your Comcast router password, you need to log into the router's admin panel. You can do this in two ways: through a web browser on any device connected to your network, or through the Xfinity app on your phone. The web browser method works on any computer, tablet, or phone — you do not need to be near the router itself.

Open a web browser and go to 192.168.0.1 or 10.0.0.1. One of these addresses will load your router's login page. If neither works, restart your router and try again. You can also type myrouter.local into the address bar, which works on most networks.

When the login page appears, enter your username and password. The default username is usually admin and the default password is motorola (or sometimes admin). If you changed these before and do not remember them, you will need to reset the router to factory settings — see the reset section below.

Key Takeaways

  • Log into your router at 192.168.0.1 or 10.0.0.1 using the default username admin and password motorola.
  • Once logged in, look for a Wireless or WiFi Settings section and find the field labeled WiFi Password, Pre-Shared Key, or Passphrase.
  • Change the password to something you can remember, save the settings, and reconnect your devices using the new password.
  • If you forgot your admin password, you can reset the router to factory defaults by holding the reset button for 10 to 15 seconds, but this erases all your custom settings.
  • The Xfinity app lets you change your WiFi password without logging into the admin panel, which is faster if you only want to update the network password.

Find the WiFi password field in the wireless settings menu

After you log in, look for a menu option called Wireless, WiFi Settings, or Advanced. The exact name depends on your router model. Click into that section and you should see a field for your current WiFi password. It may be labeled Passphrase, Pre-Shared Key, Network Key, or straightforward Password.

The password field often shows dots or asterisks instead of the actual characters for security. Look for a checkbox or button that says Show Password if you want to see what you are typing. Clear the current password and type in your new one. Most routers require passwords to be between 8 and 63 characters, and they work best with a mix of uppercase letters, lowercase letters, numbers, and symbols.

After you enter the new password, scroll down and click Save, explore, or OK. The router will process the change, which usually takes 30 seconds to a few minutes. During this time, all devices currently connected to your WiFi will be disconnected. You will need to reconnect them using the new password.

Use the Xfinity app to change your password without the admin panel

If you have the Xfinity app on your phone, you can change your WiFi password directly from there without logging into the router's web interface. Open the app, tap the menu icon (three horizontal lines), and look for Internet or WiFi Settings. Select your network and tap Change WiFi Password or Edit Network.

Type your new password and confirm it. The app will send the change to your router automatically. This method is faster if you only want to update your network password and do not need to access other router settings. However, you must be logged into your Xfinity account in the app for this to work.

Reconnect your devices after changing the password

Once the router finishes explore the change, your phone, laptop, tablet, and any other devices will lose their connection to the network. Go to your device's WiFi settings and select your network name from the list. When prompted, enter your new password exactly as you typed it — passwords are case-sensitive, so uppercase and lowercase letters matter.

If a device does not reconnect after you enter the correct password, forget the network and reconnect. On most phones, this means going to WiFi settings, tapping the network name, and selecting Forget or Remove. Then search for the network again and enter the password fresh. On Windows computers, go to Settings > Network & Internet > WiFi > Manage Known Networks, select your network, and click Forget.

Reset your router if you forgot the admin password

If you changed the default admin password and cannot remember it, you will need to reset the router to factory settings. This erases all your custom settings, including your WiFi password, and returns everything to the defaults. Look for a 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 the reset button for 10 to 15 seconds while the router is powered on. The lights on the front will blink, and the router will restart. This takes about two minutes. After it finishes, log back in using the default username admin and default password motorola, and you can set up your WiFi password again.

Be aware that resetting also erases any port forwarding rules, DNS settings, or other customizations you made. If your router is part of a business network or has special settings, contact your IT person or Comcast support before resetting.

Troubleshoot if your password change does not work

If you saved a new password but your devices still will not connect, first check that you typed it correctly when reconnecting. Passwords are case-sensitive and spaces count. If you are sure the password is right, restart your router by unplugging it for 30 seconds, plugging it back in, and waiting for it to fully boot up — the lights should stop blinking and stabilize.

If the router still will not accept connections, log back into the admin panel and verify that the password change was actually saved. Sometimes the router loses power or encounters an error before saving. If the password field is blank or shows the old password, try changing it again and wait longer before disconnecting devices.

If you see an error message like "Invalid Password Format" or "Password Too Short", your new password does not meet the router's requirements. Most Comcast routers need at least 8 characters. Try a longer password with a mix of letters and numbers.

Frequently Asked Questions

What is the default WiFi password on a Comcast router?

Comcast routers do not have a universal default WiFi password. The default password is usually printed on a sticker on the back or bottom of the router. If you cannot find it, you can reset the router to factory settings and set a new password yourself.

Can I change my WiFi password without resetting the router?

Yes. Log into the router at 192.168.0.1, find the Wireless or WiFi Settings section, and change the password there. You do not need to reset anything. Resetting should only be done if you forgot your admin login password.

Do I need to restart my router after changing the password?

The router will restart automatically when you save the new password. You do not need to unplug it. All connected devices will disconnect and you will need to reconnect them with the new password.

What if I change the password and forget it when ready?

Log back into the admin panel at 192.168.0.1 and check the password field in the Wireless Settings section. The password will be hidden as dots, but you can click "Show Password" to see it. Write it down somewhere safe this time.

Will changing my WiFi password affect my internet speed?

No. Changing the WiFi password does not change your internet speed or connection quality. It only controls who can connect to your network. Your speed depends on your Comcast plan and the strength of the signal in each room.
