Change your Cox WiFi password through the Cox website or mobile app

You can change your Cox WiFi password by logging into your Cox account online, navigating to your modem settings, and entering a new password. The process takes about five minutes and works the same way whether you use a Cox-provided modem or your own equipment. You do not need to call Cox support or restart your modem to make the change take effect.

Your WiFi password is separate from your Cox account password. Changing one does not affect the other. If you forget your Cox account password, that is a different process handled through Cox's login page.

Key Takeaways

  • Log into your Cox account at cox.com, then select your modem from the devices list to reach the WiFi settings page.
  • Your new WiFi password must be at least 8 characters long and can include letters, numbers, and symbols.
  • After you save a new password, all devices currently connected to your WiFi will stay connected, but new devices will need the new password to join.
  • If you cannot remember your Cox account login, use the "Forgot Password" link on the Cox login page to reset it before changing your WiFi password.

Step 1: Log into your Cox account online

Go to cox.com and click the "Sign In" button in the top right corner. Enter the email address or phone number associated with your Cox account, then enter your Cox account password. If you do not remember your password, click "Forgot Password" and follow the steps to reset it through email or text message.

Once you are logged in, you will see your account dashboard. Look for a section labeled "Devices," "My Services," or "Manage Devices" — the exact name varies depending on your account type.

Step 2: Find your modem and open WiFi settings

In the devices section, locate your Cox modem in the list. It will usually show the modem model number and a label like "Modem" or "Gateway." Click on it to open the modem details page.

On the modem details page, look for a link or button labeled "WiFi Settings," "Manage WiFi," or "WiFi Password." Click that link. You may be asked to log in again for security purposes — use your Cox account credentials.

Step 3: Enter your new password and save

You will see a field labeled "WiFi Password," "Network Password," or "Passphrase." Delete the current password and type your new one. Your new password must be at least 8 characters long. You can use uppercase letters, lowercase letters, numbers, and symbols like ! @ # $ % & * ( ).

Click the "Save," "explore," or "Update" button. The page will confirm that your password has been changed. This usually takes 30 seconds to one minute to take effect across your modem.

What happens to devices already connected to your WiFi

Devices that are already connected to your WiFi will remain connected after you change the password. You do not need to reconnect them. However, if a device disconnects for any reason — such as being turned off and back on — it will need the new password to reconnect.

Any new device trying to join your WiFi network will need your new password from the start. Make sure you have the new password written down or saved somewhere before you change it, so you can share it with household members or guests.

Using the Cox mobile app instead

If you prefer to use your phone, read the Cox mobile app from the Apple App Store or Google Play Store. Log in with your Cox account credentials, then navigate to "Devices" or "Services." Select your modem, then choose "WiFi Settings" or "Manage WiFi." The steps to change your password are identical to the website method.

The mobile app is useful if you are away from home and need to change your password quickly, or if you want to reset it without using a computer.

Frequently Asked Questions

Can I change my WiFi password without logging into Cox online?

Yes. You can access your modem's settings directly by typing 192.168.0.1 or 192.168.100.1 into a web browser on a device connected to your WiFi. Log in with the modem's default username and password, which are usually printed on a sticker on the modem itself. However, using your Cox account online is more find and is the recommended method.

What if I do not remember my Cox account password?

Click "Forgot Password" on the Cox login page at cox.com. Cox will send a reset link to your email address or a code to your phone number on file. Follow the instructions to create a new password, then log in and change your WiFi password as described above.

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

No. Your modem will explore the new password automatically within one minute. Restarting is not necessary and may temporarily disconnect your internet, so avoid it unless Cox support specifically asks you to.

Can I change my WiFi password if I use my own modem instead of a Cox modem?

If you own your modem, you will need to log into your modem's settings directly rather than through Cox.com. Type your modem's IP address into a browser, log in with your modem's credentials, and look for WiFi or wireless settings. The exact steps depend on your modem brand and model — check your modem's manual or manufacturer website for instructions.

What should I do if the WiFi settings page will not load?

Clear your browser's cache and cookies, then try logging in again. If the page still will not load, try a different web browser. If you continue to have trouble, you can change your password directly on the modem by typing 192.168.0.1 into your browser, or contact Cox support for information.
