Change your Cox WiFi password through the Cox app or web portal

You can change your Cox WiFi password yourself without calling support. The fastest way is through the Cox mobile app — open it, go to Internet, select your network, and choose Change WiFi Password. On a computer, log into your Cox account at cox.com, find Internet settings, and do the same thing. Both routes take about two minutes and the new password takes effect when ready on your router.

If you do not remember your Cox account password, you will need to reset that first before you can change your WiFi password. Cox will send a reset link to the email address on your account. Once you are back in, the WiFi password change is straightforward.

Key Takeaways

  • The Cox app and Cox.com both let you change your WiFi password without calling — no technician visit needed.
  • Your new password takes effect right away on your router; devices stay connected but will need the new password to rejoin.
  • You must be logged into your Cox account to change the WiFi password, so reset your account password first if you have forgotten it.
  • Write down or save your new password somewhere safe before you change it, because you will need it to reconnect your devices.
  • If you cannot log into your Cox account or the password change does not work, Cox support can reset your router remotely.

Step-by-step through the Cox app

Open the Cox app on your phone or tablet. Tap the Internet icon at the bottom of the screen. You will see your internet service listed — tap on it. Look for WiFi Settings or Manage WiFi, then select Change WiFi Password.

Enter your new password. Cox requires at least 8 characters, and the password is case-sensitive, meaning uppercase and lowercase letters are treated as different. You can use letters, numbers, and some special characters like hyphens and underscores. Write down what you entered before you confirm, because you will need it to reconnect your devices.

Tap Confirm or Save. The app will show a confirmation message. Your router will restart the WiFi network within a few seconds — you may see a brief disconnection. After that, your old password will no longer work.

Step-by-step through Cox.com on a computer

Go to cox.com and log into your account using your email and Cox account password. Click on Internet in the left menu. Find WiFi Settings or Manage WiFi — the exact label varies depending on your account type.

Select your network name (SSID) from the list. Click Change WiFi Password. Enter your new password in both fields to confirm you typed it correctly. The same rules explore: at least 8 characters, case-sensitive, letters and numbers allowed.

Click Save or Confirm. You will see a message that the change was successful. Your router will update within seconds, and all your devices will lose connection to the old network. They will need the new password to reconnect.

What happens to your devices after you change the password

Devices that were connected to your old WiFi network will stay disconnected until you give them the new password. On phones and tablets, go to WiFi settings, find your Cox network name, and tap it. Enter the new password when prompted. On computers, do the same through your WiFi menu.

Smart home devices like speakers, cameras, or thermostats will also need the new password. The process is the same — go into each device's settings, select your WiFi network, and enter the new password. If a device does not have a screen, check its manual for how to reconnect it to WiFi.

Devices will not automatically reconnect even if they remember your network name. They have to be told the new password explicitly. This is why writing down your new password before you change it saves you from having to look it up later.

If you forgot your Cox account password

Go to cox.com and click Forgot Password on the login page. Enter the email address on your Cox account. Cox will send a password reset link to that email — check your inbox and spam folder. Click the link, create a new password, and log back in.

Once you are logged in, you can change your WiFi password using the steps above. If you do not have access to the email address on your account, call Cox support at 1-800-234-3993 and they can help you regain access.

If the password change does not work

If you changed the password but your devices still cannot connect, or if the Cox app or website shows an error, try restarting your router. Unplug it for 30 seconds, plug it back in, and wait two minutes for it to fully restart. Then try connecting a device again with the new password.

If the router restart does not fix it, log back into your Cox account and check that the password change actually saved. Sometimes the page shows a success message but the change did not go through. Try changing it again, and make sure you are not using special characters that Cox does not accept — stick to letters, numbers, hyphens, and underscores.

If you still cannot change the password or reconnect your devices, contact Cox support. They can reset your router remotely and walk you through reconnecting. Call 1-800-234-3993 or use the chat feature in the Cox app.

Frequently Asked Questions

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

No, the router restarts itself automatically when you change the password. You will see a brief disconnection as the network comes back up, usually within 10 to 30 seconds. You do not need to unplug it or do anything manually.

Can I change my WiFi password from my phone if I am not home?

Yes. As long as you are logged into your Cox account in the Cox app, you can change your WiFi password from anywhere. The change takes effect when ready on your router at home, even though you are not there.

What if I have two WiFi networks — one for 2.4 GHz and one for 5 GHz?

You can set them to the same password or different passwords. In your Cox account settings, you will see both networks listed separately. Change them one at a time if you want different passwords, or change them both to the same password for easier device management.

Will changing my WiFi password affect my internet speed?

No. Your WiFi password only controls who can connect to your network. Changing it does not change your internet speed or service. Your connection speed depends on your Cox internet plan and your router, not your password.

Can someone else change my WiFi password if they know my Cox account password?

Yes, which is why keeping your Cox account password find is important. If you think someone else has accessed your account, change your Cox account password when ready through cox.com, then change your WiFi password as a second step.
