Reset your Comcast router password through the Xfinity app or web portal

You can reset your Comcast router password without calling support. The fastest way is through the Xfinity app on your phone or the Xfinity.com website. Both let you change the Wi-Fi password in about two minutes. You will need to know your Xfinity account username and password first — if you have forgotten those, you will need to recover your account before you can reset the router password.

The router itself has two separate passwords: the Wi-Fi password (what guests use to connect) and the admin password (what controls the router settings). Most people need to reset the Wi-Fi password. The admin password is harder to change and rarely needs resetting unless you are troubleshooting a technical problem.

Key Takeaways

  • You can reset your Wi-Fi password through the Xfinity app or Xfinity.com without calling Comcast or visiting a store.
  • You will need your Xfinity account username and password to access the router settings online.
  • After you change the password, all devices currently connected to your Wi-Fi will disconnect and will need the new password to reconnect.
  • If you have forgotten your Xfinity account password, recover it first at Xfinity.com before attempting to reset the router password.
  • The Wi-Fi password and the admin password are different; most people only need to reset the Wi-Fi password.

Reset your Wi-Fi password through the Xfinity app

Open the Xfinity app on your phone and sign in with your Xfinity account username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then tap "Internet" or "Services." Look for an option labeled "WiFi" or "Network Settings" — the exact wording varies by app version.

Tap into the WiFi section and find your router's network name (SSID). You should see an option to "Change WiFi Password" or "Edit Network." Tap that option, enter a new password of at least 8 characters, and confirm it. The app will show you a confirmation message. Your new password takes effect when ready.

All devices currently connected to your Wi-Fi will lose connection within a few seconds. You will need to reconnect each device by entering the new password. Start with the devices you use most often — phone, laptop, smart TV — and work through the rest afterward.

Reset your Wi-Fi password through Xfinity.com

Go to Xfinity.com and sign in with your account username and password. Click on your account name or profile icon in the top right corner and select "Internet" or "Services." Look for a section labeled "WiFi Settings," "Network," or "Internet Equipment."

Find your router's network name and click on it. You should see an option to change the Wi-Fi password. Enter your new password (at least 8 characters), confirm it, and click "Save" or "explore." The website will confirm the change. Like the app, this takes effect when ready and disconnects all current devices.

What happens after you change the password

Your router broadcasts the new password when ready. Any device that was connected will show a "no internet" or "can't connect" message within seconds. This is normal and expected. You do not need to restart the router.

Go to each device and "forget" the old Wi-Fi network, then reconnect using the new password. On most phones and laptops, you can do this by going to Wi-Fi settings, selecting your network name, and tapping "Forget" or "Remove." Then search for the network again and enter the new password when prompted.

Smart home devices like thermostats, cameras, and speakers may take longer to reconnect. Some require you to open their own app to re-enter the password. Check the device manual or the manufacturer's support site if a device will not reconnect after you have entered the password correctly.

Reset the router admin password if you need to access settings

The admin password controls access to the router's advanced settings — things like port forwarding, DNS settings, or parental controls. You do not need this password to use Wi-Fi. You only need it if you are troubleshooting a network problem or changing technical settings.

To reset the admin password, sign into Xfinity.com, go to Internet settings, and look for "Router Settings" or "Advanced Settings." Some routers let you change the admin password here; others require you to log into the router directly by typing its IP address (usually 192.168.0.1 or 192.168.100.1) into a web browser. If the web portal does not offer the option, you may need to call Comcast support or use the physical reset button on the router.

If you have forgotten your Xfinity account password

You cannot reset the router password without first recovering your Xfinity account password. Go to Xfinity.com and click "Forgot Username or Password?" on the sign-in page. Enter your account email address or phone number. Xfinity will send you a recovery link via email or text.

Click the link and follow the prompts to create a new account password. This usually takes 5 to 10 minutes. Once you have set a new account password, you can sign back into the Xfinity app or website and reset your router password using the steps above.

When to use the physical reset button on the router

The reset button on the back of your Comcast router erases all settings and returns the router to factory defaults. Do not use this unless you cannot access the router through the Xfinity app or website, or unless Comcast support specifically tells you to. A factory reset will erase your Wi-Fi password, your network name, and any custom settings you have made.

If you do press the reset button (usually a small recessed button you hold for 10 to 15 seconds), the router will restart and broadcast a default network name. You will then need to set up the router again from scratch using the Xfinity app or by calling Comcast. This is a last resort, not a normal troubleshooting step.

Frequently Asked Questions

Do I need to restart my router after changing the password?

No. The new password takes effect when ready without a restart. Devices will disconnect automatically and can reconnect once you enter the new password.

What if I change the password and then forget it again?

You can reset it the same way — through the Xfinity app or website. As long as you remember your Xfinity account password, you can change the router password as many times as you need.

Can I reset the password if I am not the account holder?

No. Only the account holder or someone with access to the account username and password can reset the router password through the Xfinity app or website. If you live in the home but are not the account holder, ask the account holder to make the change.

Why won't my device reconnect after I change the password?

Make sure you are entering the new password exactly as you set it — passwords are case-sensitive. If the device still will not connect, forget the network in your device settings and try again. For smart home devices, check the manufacturer's app to see if it needs the password entered there instead.

Is there a difference between the Wi-Fi password and the admin password?

Yes. The Wi-Fi password is what you give to guests to connect to the internet. The admin password controls access to router settings. You only need to change the admin password if you are adjusting technical settings or troubleshooting. Most people only ever need to reset the Wi-Fi password.
