Your Xfinity WiFi password is printed on a sticker attached to your modem or router

The password you need to connect devices to your home WiFi network is on a label physically attached to your Xfinity modem or gateway device. Look for a sticker on the back or bottom of the box. The password is usually listed next to "WiFi Password," "Network Key," or "PSK" (pre-shared key). Write it down or take a photo before you need it — you will not see this label again once you move the device.

If you cannot find the sticker or it has worn away, you can reset the password through your Xfinity account online or retrieve it from your account settings. The original password on the sticker is randomly generated by Comcast, but you can change it to something you remember more easily.

Key Takeaways

  • The WiFi password is printed on a sticker on the back or bottom of your Xfinity modem or gateway.
  • You can view or change your WiFi password by logging into your Xfinity account at xfinity.com.
  • If you change your password, all devices currently connected will lose WiFi access until you enter the new password.
  • The password is different from your Xfinity account login password — do not confuse the two.

Finding the password on your physical device

Turn off your modem or gateway and look at the back panel and bottom surface. Xfinity attaches a white or silver label with black text that lists your network name (SSID) and WiFi password. The label may say "WiFi Password," "Network Key," "Security Key," or "PSK." On some newer gateways, the label is on the side of the device instead.

The password is case-sensitive, meaning uppercase and lowercase letters matter. Type it exactly as it appears on the sticker, including any numbers or special characters. If you are having trouble connecting after entering the password, double-check that you are using the correct WiFi network name from the same label — Xfinity devices often broadcast two networks (one for 2.4 GHz and one for 5 GHz), and they may have slightly different names.

Viewing your password through your Xfinity account

Go to xfinity.com and sign in with your Xfinity username and password. Click on the "Internet" or "WiFi" section in your account dashboard. Look for an option labeled "WiFi Settings," "Manage WiFi," or "WiFi Password." Your current network name and password will be displayed there. You do not need to be at home to view this information — you can check it from any computer or phone with internet access.

If you have forgotten your Xfinity account password, use the "Forgot Password" link on the login page. Xfinity will send a reset link to the email address on file for your account. This is separate from your WiFi password and is only used to log into your Xfinity account online.

Changing your WiFi password

You can create a new password that is easier to remember than the random one Xfinity assigned. Log into your Xfinity account, navigate to WiFi settings, and look for an option to "Change Password" or "Edit WiFi Settings." Enter your new password — Xfinity requires at least 8 characters, and most systems accept letters, numbers, and common symbols like hyphens or underscores.

After you change the password, your WiFi network will disconnect all devices that are currently connected. You will need to reconnect each device by entering the new password. This includes phones, tablets, computers, smart TVs, and any other WiFi-enabled devices in your home. The change usually takes effect within a few minutes.

What to do if you cannot find the password

If the sticker is missing or unreadable and you cannot access your Xfinity account online, you have two options: reset the device to factory settings or contact Xfinity support. Resetting the modem will erase your current WiFi password and restore the original one printed on the label — but this only works if you can read that label. If the label is completely gone, you will need to call Xfinity or use their online chat to have a representative help you recover or reset your password.

Xfinity support can be reached by phone at the number on your bill, through the Xfinity app, or by visiting xfinity.com/support. Have your account number ready. Support representatives can confirm your identity and either tell you your current password or help you set a new one.

Resetting your modem to restore the original password

If you changed your WiFi password and now cannot remember it, you can reset the modem to bring back the original password from the factory label. Locate the small reset button on the back of your modem — it is usually recessed so you cannot press it by accident. Use a paperclip or the tip of a pen to press and hold the button for 10 to 15 seconds while the device is powered on. The lights on the front will blink and the modem will restart.

After the reset completes (usually within 5 minutes), the WiFi network will broadcast with the original network name and password from the label. All your devices will be disconnected, and you will need to reconnect them using the original password. This reset also clears any other changes you made to your network settings, so your internet connection will return to Xfinity's default configuration.

Frequently Asked Questions

Is the WiFi password the same as my Xfinity account password?

No. 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 home network. They are completely separate. You can change one without affecting the other.

Can I see my WiFi password if I am away from home?

Yes. Log into your Xfinity account from any computer or phone with internet access, go to WiFi settings, and your password will be displayed. You do not need to be physically near your modem.

What happens if I change my WiFi password?

All devices currently connected to your WiFi will lose their connection. You will need to reconnect each device by entering the new password. Devices that were previously connected will not automatically reconnect — you must manually select your network and enter the new password on each one.

Why does my Xfinity gateway show two WiFi networks?

Most Xfinity gateways broadcast both a 2.4 GHz network and a 5 GHz network. Both use the same password, but the 5 GHz network is faster over shorter distances and the 2.4 GHz network has better range through walls. You can connect to either one — they are the same network with different names.

Can I reset my modem without losing my internet connection?

A factory reset will temporarily disconnect your internet while the modem restarts — usually for 3 to 5 minutes. Your internet will come back on automatically once the reset is complete. If you only want to change your WiFi password without resetting everything else, use your Xfinity account online instead of the reset button.
