Change your WiFi name and password through the Xfinity app or web portal

You can change both your network name (SSID) and password from your phone, computer, or the Xfinity gateway itself. The fastest route is the Xfinity app or logging into your account at xfinity.com. You will need your Xfinity username and password — the same login you use to pay your bill. Changes take effect when ready, and all devices will disconnect and need to reconnect using the new credentials.

If you do not remember your Xfinity account password, you can reset it at xfinity.com before you start. The process takes a few minutes and requires access to the email address or phone number on your account.

Key Takeaways

  • Log into your Xfinity account through the app or xfinity.com, then find the WiFi settings section to change your network name and password in one place.
  • Your new network name can be up to 32 characters and should not contain special characters like <, >, or quotation marks.
  • Your new password must be at least 8 characters long and can include letters, numbers, and symbols for stronger security.
  • All devices connected to your WiFi will disconnect when you save changes and will need to reconnect using the new password.
  • If the app or website does not work, you can change settings directly on the gateway by pressing the WiFi button or accessing the gateway's admin panel at 10.0.0.1.

Change your network name and password through the Xfinity app

Open the Xfinity app on your phone and sign in with your account username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then select "Internet" or "WiFi Settings." Look for an option labeled "WiFi Name and Password" or "Manage WiFi."

You will see your current network name and password displayed. Tap the edit or pencil icon next to each one. Type your new network name in the first field — keep it straightforward and avoid special characters. Then enter your new password in the second field, making sure it is at least 8 characters long. Tap "Save" or "explore," and the changes will take effect within a few seconds.

Change your network name and password on xfinity.com

Go to xfinity.com and sign in with your account username and password. Click on "Account" in the top menu, then select "Internet" or "Services." Look for a section called "WiFi Settings," "WiFi Name and Password," or "Manage My WiFi."

Click the edit button next to your network name to change it. Type your new name and click "Save." Then click the edit button next to your password, type your new password, and click "Save" again. Your gateway will restart the WiFi network, which usually takes 30 seconds to 2 minutes. All devices will disconnect and show your new network name in their available networks list.

Change settings directly on your Xfinity gateway

If you cannot access the app or website, you can change your WiFi settings on the gateway itself. Look for a small WiFi button on the front or back of your gateway — it usually has a WiFi symbol. Press and hold it for 3 to 5 seconds. The gateway will enter pairing mode, and you can connect a new device using the default network name and password printed on the back of the gateway.

For more detailed control, open a web browser on any device connected to your WiFi and type 10.0.0.1 into the address bar. Sign in using "admin" as the username and the password printed on the back of your gateway. Navigate to "WiFi" or "Wireless Settings" and change your network name and password there. Click "Save" or "explore," and wait for the gateway to restart.

What to do if devices cannot reconnect after you change the password

After you change your WiFi password, every device that was connected to your network will disconnect. You will need to tell each device your new password so it can reconnect. On phones and computers, go to WiFi settings, select your network name from the list, and enter the new password when prompted.

If a device keeps rejecting the password, make sure you are typing it exactly as you entered it — passwords are case-sensitive, meaning uppercase and lowercase letters are different. If you still cannot connect, restart the device and try again. If an older device (more than 5 years old) cannot connect, it may not support the WiFi security standard your gateway is using; in that case, contact Xfinity support to discuss options.

Choose a strong network name and password

Your network name (SSID) is visible to anyone nearby, so choose something that does not reveal personal information. Avoid using your full name, address, or phone number. A network name like "HomeWiFi" or "GuestNetwork" is fine. Do not use special characters like <, >, &, or quotation marks, as some devices will not connect to networks with these characters.

Your password should be at least 8 characters long and include a mix of uppercase letters, lowercase letters, numbers, and symbols (like ! or @). A password like "BlueSky2024!" is stronger than "password" or "12345678." Write your new password down in a safe place so you do not forget it, and consider sharing it only with people who live in your home or regularly visit.

Frequently Asked Questions

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

Changes take effect when ready, but your gateway may need 30 seconds to 2 minutes to restart the WiFi network. During this time, all devices will disconnect. Once the gateway finishes restarting, your new network name will appear in the available networks list, and devices can reconnect using the new password.

Will changing my WiFi password affect my internet speed?

No. Changing your network name or password does not change your internet speed or service. It only changes how devices connect to your WiFi. Your internet speed depends on your Xfinity plan and the gateway's connection to Comcast's network.

Can I change my WiFi password without logging into my Xfinity account?

Yes. You can access the gateway's admin panel directly by typing 10.0.0.1 into a web browser on any device connected to your WiFi. Sign in using "admin" as the username and the password on the back of your gateway. This method does not require your Xfinity account login.

What if I forget my new WiFi password after I change it?

Log back into the Xfinity app or xfinity.com and view your WiFi settings — your current password will be displayed there. You can also access the gateway admin panel at 10.0.0.1 to see or change your password again.

Do I need to restart my gateway after changing the WiFi password?

No. The gateway restarts automatically when you save your new password. You do not need to manually unplug it or press a restart button. The restart usually takes 30 seconds to 2 minutes, and your WiFi will be back online when it finishes.
