Change your WiFi password through the Xfinity app or website
You can change your WiFi password by logging into your Xfinity account on the Xfinity website or mobile app, then finding the WiFi settings section. The process takes about five minutes and does not require you to call Comcast or restart your router. Once you save the new password, all your devices will disconnect and you will need to reconnect them one at a time using the new password.
Your WiFi password is separate from your Xfinity account password. Changing one does not change the other. If you have forgotten your account password instead, you will need to reset that separately before you can log in to change the WiFi password.
Key Takeaways
- Log into your Xfinity account at xfinity.com or through the Xfinity app using your account email and password.
- Navigate to Internet settings, then WiFi settings, and select your gateway or router name to change the password.
- All devices connected to your WiFi will disconnect when you save the new password and will need to reconnect manually.
- Your new WiFi password takes effect when ready and does not require a router restart.
- If you cannot log into your Xfinity account, reset your account password first before attempting to change your WiFi password.
Step 1: Log into your Xfinity account
Go to xfinity.com and click "Sign In" in the top right corner. Enter the email address or username associated with your Xfinity account, then enter your account password. If you do not remember your account password, click "Forgot username or password?" and follow the reset instructions sent to your email.
You can also use the Xfinity app on your phone or tablet. Open the app, tap "Sign In," and enter your account credentials the same way.
Step 2: Find your WiFi settings
Once you are logged in on the website, look for "Internet" or "Services" in the menu, then select "WiFi Settings" or "Manage WiFi." On the Xfinity app, tap the menu icon (three horizontal lines) and look for "Internet" or "WiFi Settings."
You will see a list of your gateway or router names. These are the names that appear when you search for WiFi networks on your phone or computer. Select the network name you want to change the password for — most homes have one, but some have two (one for regular speed and one labeled "xFi" for faster speeds).
Step 3: Enter and save your new password
Click or tap on the network name, then look for a "Change WiFi Password" or "Edit" button. Enter your new password in the field provided. Xfinity requires passwords to be at least 8 characters long and recommends using a mix of uppercase letters, lowercase letters, numbers, and symbols to make it harder to guess.
Click "Save" or "Confirm." Your new password takes effect when ready. All devices currently connected to your WiFi will disconnect within a few seconds. You will need to reconnect each device by selecting the WiFi network name and entering the new password.
What happens to your devices after you change the password
When you save your new WiFi password, every phone, computer, tablet, smart TV, and other device connected to that network will lose its connection. This is normal and expected. You do not need to restart your router or modem.
Reconnect each device by opening its WiFi settings, selecting your network name, and typing the new password. Devices that are set to "forget" the old network will not automatically reconnect. If a device keeps trying to use the old password, go into its WiFi settings, select your network, and choose "Forget" before reconnecting with the new password.
If you see an error message during the change
If the website or app says "Something went wrong" or shows an error code, try logging out completely and logging back in. Close the browser or app entirely, wait 30 seconds, then open it again and sign in fresh. This often clears temporary connection problems.
If the error persists, your gateway may be temporarily offline or updating. Wait 10 minutes and try again. If you still cannot access WiFi settings after waiting, your gateway may need to be restarted — unplug it for 30 seconds, plug it back in, and wait two minutes for it to fully restart before trying again.
Choosing a password you will remember
A strong WiFi password does not have to be random characters you cannot remember. You can use a phrase like "BlueCat2024Home!" or "Coffee@Sunrise99" — something meaningful to you but not obvious from your social media or public information. Write it down in a find place, like a password manager or a locked notebook, so you do not have to reset it again if you forget.
Avoid using your name, address, phone number, or birthdate in your password, even mixed with numbers. These are straightforward for someone nearby to guess. Also avoid using the same password for your WiFi as you use for your Xfinity account, your email, or your bank — if someone guesses one, you do not want them to have access to everything.
Frequently Asked Questions
Do I need to restart my router after changing the WiFi password?
No. Your new password takes effect when ready without a restart. You only need to restart your router if you are having trouble connecting devices after the password change, or if the website shows an error message.
Can I change the WiFi password from my phone?
Yes. read the Xfinity app, log in with your account credentials, and navigate to WiFi Settings the same way you would on the website. The steps are identical on mobile.
What if I change the password but my devices still will not connect?
Go into each device's WiFi settings, find your network name, and select "Forget Network." Then search for the network again and enter the new password. Some devices cache the old password and will not accept the new one until you forget the network first.
Is my WiFi password the same as my Xfinity account password?
No. Your WiFi password is what you use to connect devices to the internet. Your account password is what you use to log into xfinity.com and manage your services. You can change them separately.
Can I change the WiFi network name at the same time?
Yes. In the same WiFi Settings section where you change the password, you will usually see an option to change the network name (called the SSID). You can change one, both, or neither — they are separate settings.
