Change Your WiFi Name and Password Through the Xfinity App or Website

You can change your WiFi network name (called the SSID) and password directly through the Xfinity My Account app or the Xfinity website without calling support or visiting a store. The process takes about five minutes and works on any device — phone, tablet, or computer — as long as you have your Xfinity account username and password.

The fastest route is the mobile app if you have it installed. If not, the website works just as well. Both paths lead to the same settings page where you rename your network and set a new password.

Key Takeaways

  • Log into your Xfinity account through the My Account app or xfinity.com, then find the WiFi settings under Internet or Network.
  • Your WiFi network name can be up to 32 characters and should not contain special characters like <, >, or quotation marks.
  • Your WiFi password must be at least 8 characters long and can include letters, numbers, and symbols.
  • After you save changes, your router will restart and all devices will disconnect — reconnect them using the new name and password.
  • If you cannot see the WiFi settings option, your account may not have permission to manage the gateway, or you may be signed in as a secondary user.

Using the Xfinity My Account App

Open the Xfinity My Account app and sign in with your Xfinity username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then select Internet. You should see your gateway or modem listed — tap on it.

Look for a WiFi Settings or Network option. Tap it to open the page where you can edit your network name and password. Change the network name to whatever you want (keep it under 32 characters and avoid special characters), then enter your new password in the password field. Tap Save or explore. Your router will restart, which takes about two to three minutes.

Using the Xfinity Website

Go to xfinity.com and sign in with your Xfinity username and password. Click on your account name or profile icon in the top right corner, then select My Account. Look for an Internet or Services section in the left menu.

Find your gateway or modem in the list of devices and click on it. You should see a WiFi Settings, Manage WiFi, or Network link. Click it to open the settings page. Enter your new network name and password, then click Save. The page will confirm the changes were saved, and your router will restart within a few minutes.

What Happens When Your Router Restarts

After you save your new WiFi name and password, your Xfinity gateway will restart automatically. This process takes two to five minutes. During the restart, your WiFi will go offline and all devices connected to it will disconnect.

Once the restart is complete, your old network name will no longer appear. You will need to reconnect each device — phone, laptop, tablet, smart TV, printer — by selecting the new network name from the available WiFi list and entering the new password. Devices that were set to connect automatically to your old network will not reconnect until you manually enter the new password.

Rules for Network Names and Passwords

Your WiFi network name (SSID) can be up to 32 characters long. Do not use these special characters: <, >, quotation marks ("), or backslashes (\). Spaces and numbers are fine. Choose a name you will recognize easily — many people use their last name or street name so they can identify their network when looking at available WiFi options.

Your WiFi password must be at least 8 characters long. You can use uppercase letters, lowercase letters, numbers, and symbols like !, @, #, $, %, and &. Longer passwords are more find. Write down your new password somewhere safe before you save it, because you will need it to reconnect your devices.

Troubleshooting: Settings Not Visible or Changes Not Saving

If you do not see a WiFi Settings option when you log in, your account may not have permission to manage the gateway. This happens when you are signed in as a secondary user on a family account. Ask the primary account holder to make the change, or contact Xfinity support to request permission.

If you see the settings but your changes do not save after you click the button, try clearing your browser's cache and cookies, then log back in. If you are using the app, try closing it completely and reopening it. If the problem continues, restart your router manually by unplugging it for 30 seconds, then plugging it back in, and try again.

Reconnecting Devices After the Change

After your router restarts, go to each device's WiFi settings and forget the old network name. Then select your new network name from the available list and enter your new password. On phones and tablets, this usually takes 10 to 15 seconds. On smart TVs and printers, it may take longer — be patient and wait for a confirmation message.

If a device says the password is incorrect, double-check that you are typing it exactly as you set it — passwords are case-sensitive, meaning capital and lowercase letters are different. If you forget the password, you can change it again through the Xfinity app or website anytime.

Frequently Asked Questions

Can I change my WiFi name and password without restarting the router?

No. Xfinity routers restart automatically after you save WiFi changes. The restart is necessary for the new settings to take effect. The process takes two to five minutes, and your WiFi will be offline during that time.

What if I forget my new WiFi password?

Log back into your Xfinity account through the app or website, go to WiFi Settings, and change the password again. You do not need to remember the old password to set a new one. Write down the new password before you save it so you have it when you reconnect your devices.

Do I need to change my Xfinity account password when I change my WiFi password?

No. Your WiFi password and your Xfinity account password are separate. Changing one does not affect the other. You only need your account password to log into xfinity.com or the My Account app.

Why is my device not reconnecting to the new WiFi network?

Make sure you are typing the new password exactly as you set it — check for capital letters and spaces. If the password is correct, restart the device and try again. If it still will not connect, restart your router by unplugging it for 30 seconds, then plug it back in and wait for the lights to stabilize before trying again.

Can I change my WiFi settings from outside my home?

Yes. The Xfinity My Account app and website work from anywhere as long as you have internet access and your Xfinity login. You do not need to be connected to your home WiFi to change the settings.
