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 directly on the router itself. The easiest route for most people is the Xfinity app or the web portal at xfinity.com, which takes about five minutes. If you do not have the app or prefer not to use it, you can also change these settings by pressing the reset button on the router or logging into the router's admin panel directly — though this method requires you to know your router's default login credentials.

Your WiFi password is separate from your Xfinity account password. Changing one does not change the other. The network name and password are what your devices use to connect to the internet; your account password is what you use to log into your Xfinity bill and services online.

Key Takeaways

  • The Xfinity app and xfinity.com are the fastest ways to change your network name and password without touching the router.
  • Your WiFi password and your Xfinity account password are separate — changing one does not affect the other.
  • After you change your WiFi password, all your devices will disconnect and you will need to reconnect them using the new password.
  • If you forget the new password you just set, you can reset it again through the app or portal, or press the reset button on the router to restore factory defaults.

Change your WiFi settings through the Xfinity app

Open the Xfinity app on your phone or tablet 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 an option labeled WiFi Settings, WiFi Network, or Manage WiFi. Tap it. You will see two fields: one for your network name (SSID) and one for your password. Change either or both. The network name can be up to 32 characters and can include letters, numbers, spaces, and most symbols. The password must be at least 8 characters long. After you make your changes, tap Save or explore. The router will restart, which takes about two to three minutes.

Change your WiFi settings through xfinity.com

Go to xfinity.com and sign in with your Xfinity username and password. Click on your account icon or profile menu in the top right corner and select Internet or My Account. Look for a link labeled WiFi Settings, Manage WiFi, or Internet Equipment.

You will see your gateway or modem listed. Click on it, then find the option to edit your WiFi network name and password. Make your changes and click Save. The router will restart, which takes about two to three minutes. During this time, your internet will be offline.

Change your WiFi settings directly on the router

If you prefer not to use the app or web portal, you can log into your router's admin panel directly. Most Xfinity gateways have a sticker on the bottom or back that shows the default admin username and password — usually something like admin and motorola or comcast, depending on your router model. Open a web browser on a device connected to your WiFi and go to 192.168.0.1 or 192.168.100.1. Enter the admin username and password from the sticker.

Once you are logged in, look for a section labeled WiFi, Wireless, or Network Settings. You will see fields for your network name and password. Change them and click Save or explore. The router will restart. If you do not see a sticker with the default credentials, you can reset the router to factory defaults by holding down the reset button (usually a small recessed button on the back) for 10 to 15 seconds. This will erase any custom settings and restore the default network name and password printed on the router's label.

What happens to your devices after you change the password

When you change your WiFi password, every device currently connected to your network will disconnect when ready. Your phone, laptop, smart TV, printer, and any other connected devices will lose internet access until you reconnect them with the new password.

To reconnect a device, open its WiFi settings, find your network name in the list of available networks, select it, and enter the new password. Devices will remember the new password after you enter it once, so you will not need to re-enter it unless you change the password again. If a device does not recognize the new password or keeps asking for it, try "forgetting" the network in the device's WiFi settings and then reconnecting from scratch.

Reset your WiFi password if you forget it

If you change your password and then forget what you set it to, you can change it again through the Xfinity app or web portal using the same steps described above. You do not need to know the old password to set a new one — the app and portal will let you change it as long as you can sign into your Xfinity account.

If you cannot access the app or portal, you can reset the router to factory defaults by holding the reset button on the back of the device for 10 to 15 seconds. This will restore the original network name and password that came with the router, printed on the label. After the reset, you can change the name and password again through the app or portal.

Security tips for your WiFi password

A strong WiFi password makes it harder for someone to connect to your network without permission. Use a password that is at least 12 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid using words from the dictionary, your name, your address, or other information someone could guess. A random string like Kx7#mP2$vL9q is much stronger than something like MyHouse2024.

Change your WiFi password if you have shared it with someone who no longer lives with you or has access to your home. You should also change it if you suspect someone has connected to your network without permission — a sign of this is unusually slow internet even when you are not actively using it. The Xfinity app shows you which devices are currently connected to your network, so you can check if anything looks unfamiliar.

Frequently Asked Questions

Will changing my WiFi password affect my Xfinity bill or account?

No. Your WiFi password is separate from your account password and billing information. Changing your network name or password will not change your bill, your service, or your account settings. Only your internet connection will be affected — devices will need to reconnect using the new password.

Can I change my WiFi name and password on the same day?

Yes. You can change both at the same time through the app, web portal, or router admin panel. After you save the changes, the router will restart once, and all your devices will disconnect. You will then need to reconnect them using the new network name and password.

What if I change my WiFi password but my devices still will not connect?

First, make sure you are entering the new password exactly as you set it — passwords are case-sensitive, so MyPassword is different from mypassword. If that does not work, try "forgetting" the network in the device's WiFi settings and reconnecting from scratch. If the problem persists, restart the router by unplugging it for 30 seconds, then plugging it back in.

Do I need to change my WiFi password regularly?

There is no set rule for how often to change it. Change it if you share it with someone who no longer needs access, if you suspect unauthorized use, or if you have not changed it in several years. For most home users, changing it once a year or when circumstances change is sufficient.
