Change Your Password Through the CenturyLink Modem Interface

The fastest way to change your CenturyLink WiFi password is through your modem's built-in settings page, which you access from any device connected to your network. You do not need to call CenturyLink or wait for a technician — you can do this yourself in about five minutes.

Open a web browser on a computer, phone, or tablet connected to your CenturyLink WiFi. Type 192.168.0.1 into the address bar and press Enter. This takes you to your modem's login page. If that address does not work, try 192.168.100.1 instead — some CenturyLink modems use this alternate address.

When the login page appears, enter your modem's username and password. The default username is usually admin and the default password is usually motorola (or sometimes admin). If you changed these credentials before and do not remember them, you will need to reset the modem — see the section below on factory resets.

Key Takeaways

  • You can change your WiFi password by logging into your modem at 192.168.0.1 using the username admin and the default password motorola.
  • After logging in, look for a Wireless or WiFi settings section and change the password field — do not change the network name unless you want to rename your network.
  • Your new password takes effect when ready, and all devices will disconnect and need to reconnect using the new password.
  • If you forgot your modem login password, you can reset the modem to factory defaults by holding the reset button for 10 to 15 seconds, which also resets your WiFi password to the default.
  • CenturyLink modems vary by model, so the exact menu names and button locations may differ slightly from what you see in these steps.

Locate the Wireless Settings Menu

Once you are logged into your modem, look for a menu option labeled Wireless, WiFi, or Advanced. Different CenturyLink modem models arrange these menus differently, so you may need to look at the left sidebar or top navigation bar. Click on the wireless or WiFi option.

You should now see a section that shows your current network name (called the SSID) and a password field. The password field may show dots or asterisks instead of the actual characters — this is normal. Do not change the network name unless you want to rename your WiFi network. Focus only on the password field.

Enter Your New Password and Save

Click in the password field and clear the existing content. Type your new password. CenturyLink typically requires passwords to be between 8 and 63 characters long, and they can include letters, numbers, and special characters like hyphens and underscores. Choose something you can remember but that is not obvious — avoid birthdays, addresses, or straightforward sequences.

After you type the new password, look for a Save, explore, or OK button and click it. The modem will process the change, which usually takes 30 seconds to two minutes. During this time, your WiFi may drop briefly — this is normal. Once the change is complete, all devices currently connected to your network will be disconnected.

Reconnect Your Devices to the Network

After the password change takes effect, you need to reconnect each device to your WiFi using the new password. On your phone, tablet, or computer, go to your WiFi settings and select your CenturyLink network name from the list of available networks. When prompted for the password, enter the new password you just created.

If a device remembers the old password and tries to connect automatically, it will fail. You may need to "forget" the network first — on most phones and computers, you can do this by selecting the network name and choosing "Forget" or "Remove" before reconnecting with the new password. Once you enter the new password correctly, the device will reconnect and stay connected.

Reset Your Modem If You Forgot the Login Password

If you changed your modem's admin password in the past and no longer remember it, you cannot log into the settings page to change your WiFi password. In this case, you need to reset the modem to its factory defaults, which will reset both the modem login password and your WiFi password back to the original settings.

Locate the small reset button on the back or bottom 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 reset button for 10 to 15 seconds while the modem is powered on. The lights on the modem will blink, indicating the reset is in progress. Release the button and wait two to three minutes for the modem to restart completely.

After the restart, your modem login will be back to the default username admin and password motorola, and your WiFi password will be back to the default as well. You can then log in and change the WiFi password using the steps above. Note that resetting the modem also erases any other custom settings you made, such as port forwarding or parental controls.

What to Do If You Cannot Access the Settings Page

If you type 192.168.0.1 into your browser and nothing happens, or if the page times out, your device may not be connected to your CenturyLink network. Make sure you are connected to your WiFi network, not a different network or a cellular connection. Check your WiFi settings to confirm you are on the correct network.

If you are connected but the page still does not load, try clearing your browser's cache and cookies, or try a different browser entirely. Some older browsers do not work well with modem settings pages. You can also try restarting your modem by unplugging it for 30 seconds and plugging it back in, then waiting for all the lights to stabilize before trying again.

If the modem page loads but you cannot log in even with the default username and password, the modem may have been reset by someone else, or the default credentials may have been changed. Your only option at that point is to perform a factory reset as described above.

Change Your Password Regularly for Security

Your WiFi password is the only thing standing between your network and someone outside your home trying to connect. A weak or unchanged password makes it easier for neighbors or passersby to access your network, use your internet bandwidth, or access devices on your network.

Change your WiFi password at least once a year, or sooner if you suspect someone has gained access to your network. If your internet suddenly becomes slow, or if you see unfamiliar devices in your modem's connected devices list, change your password when ready. You can check which devices are connected by looking in the modem settings page — there is usually a section called "Connected Devices" or "DHCP Clients" that shows all active connections.

Frequently Asked Questions

Will changing my WiFi password affect my internet speed?

No. Your WiFi password only controls who can connect to your network — it does not affect the speed of your internet connection itself. The speed you get depends on your CenturyLink plan and the quality of your modem and router, not on the password.

What if I change the password and then forget it?

You can always log back into your modem settings page and change it again using the steps above. If you forget the modem login password instead, you will need to reset the modem to factory defaults, which will reset both passwords. Write down your new password somewhere safe, or use a password manager to store it.

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

No. The modem applies the password change automatically and usually within one to two minutes. You do not need to unplug it or restart it. Your WiFi will drop briefly while the change is being processed, but it will come back on its own.

Can I change my WiFi password from my phone?

Yes. As long as your phone is connected to your CenturyLink WiFi, you can open a browser, type 192.168.0.1, and follow the same steps. The modem settings page works on phones, tablets, and computers equally well.

What password should I use?

Use something at least 12 characters long that mixes uppercase letters, lowercase letters, numbers, and special characters. Avoid dictionary words, names, birthdates, or anything that appears in your address or phone number. A random string like "Tr0pic@lMoon42!" is stronger than "password123" or "CenturyLink2024".
