Change Your WiFi Name and Password Through the Xfinity App or Website
You can change both your WiFi network name (SSID) and password through the Xfinity app on your phone or through the Xfinity website on any browser. Log into your Xfinity account, find the WiFi settings section, and you'll see fields for the network name and password. After you save the changes, your modem will restart — this takes about two to three minutes, and all devices will disconnect during that time.
The Xfinity app is usually faster if you're on your phone. Open the app, tap the menu icon, select "Internet," then "WiFi Settings." The website route works the same way: go to xfinity.com, sign in, click "Internet," then "WiFi Settings." Both paths lead to the same control panel.
Write down your new password before you save it. You'll need to enter it on every device that connects to your WiFi — phones, laptops, tablets, smart TVs, and anything else that uses your network. If you forget it after the change, you can always log back in and view it again.
Key Takeaways
- You can change your WiFi name and password through the Xfinity app or at xfinity.com by signing into your account and navigating to WiFi Settings.
- Your modem will restart after you save changes, disconnecting all devices for two to three minutes.
- Every device on your network will need to reconnect using the new password after the change takes effect.
- If you forget the new password, you can log back into your Xfinity account and view it in the WiFi Settings section.
- You can also change these settings directly on the modem itself by entering 192.168.0.1 in a web browser, though the app or website is simpler for most people.
What Happens When You Change Your WiFi Name
When you change your network name, your WiFi will show up under the new name on the list of available networks. Any device that was previously connected will no longer see your old network name and will need to be told to "forget" the old connection before it can connect to the new one.
Changing the name doesn't affect your internet speed or connection quality — it's purely cosmetic. Some people change it to something more personal, others change it to make it less obvious which router brand they own, and some change it just to match a new password they've created. The name can be up to 32 characters long and can include spaces and most special characters.
What Happens When You Change Your Password
Your password is what keeps other people from connecting to your WiFi without permission. When you change it, every device currently connected will stay connected until you restart the modem or until that device disconnects on its own. Once the modem restarts, those devices will lose their connection and won't be able to reconnect until you enter the new password.
A strong password should be at least 12 characters long and mix uppercase letters, lowercase letters, numbers, and symbols. Comcast will accept passwords up to 63 characters. If you create a password that's hard to remember, store it in a password manager like Bitwarden, 1Password, or the password manager built into your phone's settings.
Reconnecting Devices After the Change
After your modem restarts, go to each device and open the WiFi settings. Find your network name in the list of available networks, tap or click it, and enter your new password. Phones and tablets usually remember the password once you enter it correctly, so you won't have to type it again. Computers, smart TVs, and other devices work the same way.
If a device says "incorrect password" when you know you typed it right, check that you didn't accidentally turn on Caps Lock. Passwords are case-sensitive, meaning uppercase and lowercase letters are treated as different characters. If you're still stuck, you can always log back into your Xfinity account and double-check what password you set.
Changing Settings Directly on the Modem
If you prefer not to use the app or website, you can change your WiFi name and password by connecting directly to your modem's control panel. Open a web browser on any device connected to your WiFi and type 192.168.0.1 into the address bar. You'll be asked to log in — the default username is usually "admin" and the default password is on a sticker on the back or bottom of your modem.
Once you're logged in, look for a section called "WiFi Settings," "Wireless," or "Network." The exact wording depends on your modem model, but the fields for network name and password are always there. After you save your changes, the modem will restart just as it does through the app or website.
This method is useful if you're having trouble with the app or website, or if you want to change settings without needing to remember your Xfinity account password. However, most people find the app or website easier because they don't have to look up the modem's login credentials.
Resetting Your WiFi Name and Password to Defaults
If you want to go back to Comcast's default settings, you can reset your WiFi through the Xfinity app or website. In the WiFi Settings section, look for a "Reset" or "Restore Defaults" button. This will change your network name back to something like "XFINITY" or "XFINITY-XXXX" (where the X's are numbers from your modem's serial number) and set the password back to the one printed on your modem's sticker.
Resetting is useful if you've forgotten your password and can't access your Xfinity account, or if you're selling or giving away your modem and want to clear your custom settings. After a reset, you'll need to reconnect all your devices using the default credentials.
Troubleshooting Connection Problems After Changing Your Password
If devices won't connect after you've changed your password, the most common cause is a typo. Passwords are case-sensitive and spaces count, so "MyPassword123!" is different from "mypassword123!". Go back into your Xfinity account and verify the exact password you set, then try entering it again on the device that's having trouble.
If the password is definitely correct but the device still won't connect, try "forgetting" the network on that device and reconnecting from scratch. On phones and tablets, go to WiFi settings, find your network name, and select "Forget." Then find the network again in the list and enter the password as if you're connecting for the first time. On computers, the process is similar — look for "Manage Known Networks" or "Forget This Network" in your WiFi settings.
If you're still having trouble after trying these steps, restart your modem by unplugging it for 30 seconds, then plugging it back in. Wait for all the lights to stabilize before trying to connect again. If the problem persists, contact Comcast support — they can check whether your modem is working correctly and help you troubleshoot from there.
Frequently Asked Questions
Do I need to change my Xfinity account password when I change my WiFi password?
No, these are two separate passwords. Your Xfinity account password is what you use to log into xfinity.com or the Xfinity app. Your WiFi password is what devices use to connect to your internet. You can change one without changing the other.
Will changing my WiFi name or password affect my internet speed?
No. Your WiFi name and password are just identifiers and security settings. Changing them won't make your connection faster or slower. Your speed depends on your internet plan and the modem's distance from your devices.
What if I change my WiFi password and then forget it?
Log back into your Xfinity account through the app or website, go to WiFi Settings, and you'll see your current password displayed there. You can view it, copy it, or change it to something new if you'd like.
Can I change my WiFi settings if I'm not connected to the internet?
You can change settings through the modem's control panel (192.168.0.1) as long as you're connected to the WiFi itself, even if the modem isn't connected to the internet. You cannot use the Xfinity app or website without an active internet connection.
How often should I change my WiFi password?
There's no set rule. Change it if you think someone unauthorized has connected to your network, if you've shared it with someone who no longer needs access, or straightforward if you want to. Changing it every few months is reasonable for security, but it's not required.
