Change your Cox WiFi password through the Cox web portal or the Cox mobile app
The fastest way to change your WiFi password is to log into your Cox account online at cox.net, go to the Internet section, find your modem settings, and update the password there. The whole process takes about five minutes. You can also use the Cox mobile app if you prefer to do it from your phone.
After you change the password, all your devices will disconnect from WiFi. You'll need to reconnect each one using the new password. Devices that are currently connected will drop off when ready, so plan the change for a time when nobody is actively using the internet.
If you don't remember your Cox account password, you'll need to reset that first before you can change your WiFi password. That's a separate step from changing the WiFi password itself.
Key Takeaways
- Log into cox.net with your Cox account username and password, then navigate to Internet settings to change your WiFi password.
- The Cox mobile app offers the same password change option if you want to do it from your phone instead of a computer.
- All devices connected to your WiFi will disconnect when you change the password and will need to reconnect with the new one.
- If you've forgotten your Cox account password, reset it first at cox.net before attempting to change your WiFi password.
- Your WiFi password is different from your Cox account password — changing one does not change the other.
Step-by-step: changing your password on the Cox website
Start by opening a web browser and going to cox.net. Click "Sign In" in the top right corner and enter your Cox account username (usually your email address) and your Cox account password. Once you're logged in, look for "Internet" or "My Services" in the main menu.
Find the section labeled "Modem" or "WiFi Settings." Click on it to expand your modem details. You should see your current WiFi network name (SSID) and a button or link that says "Change WiFi Password" or "Manage WiFi." Click that button.
Enter your new password in the field provided. Cox requires WiFi passwords to be at least 8 characters long and to include a mix of uppercase letters, lowercase letters, numbers, and special characters (like ! or @). The system will show you whether your password meets these requirements as you type.
Click "Save" or "explore" to confirm the change. The Cox website will show you a confirmation message. Your new password is now active, and any device still connected to your WiFi will be disconnected within a few seconds.
Using the Cox mobile app to change your password
Open the Cox mobile app on your phone and sign in with your Cox account username and password. Tap the menu icon (usually three horizontal lines) and look for "Internet" or "Services."
Select your modem from the list of devices. You should see a "WiFi Settings" or "Change Password" option. Tap it and enter your new password following the same requirements as the website: at least 8 characters with uppercase, lowercase, numbers, and a special character.
Tap "Save" or "Confirm." The app will show a confirmation that the change was successful. Like the website method, all connected devices will disconnect and need to reconnect with the new password.
What happens to your devices after you change the password
When your WiFi password changes, every device currently connected to that network will lose its connection within seconds. This includes phones, tablets, laptops, smart TVs, smart home devices, and anything else using that WiFi network.
To reconnect a device, open its WiFi settings, find your Cox network name in the available networks list, select it, and enter your new password. The device will then reconnect and work normally. You'll need to do this for each device separately.
Some devices may try to reconnect automatically using the old password and will show an error message. This is normal — just forget the old network in the device's WiFi settings and reconnect with the new password.
If you've forgotten your Cox account password
You cannot change your WiFi password without first logging into your Cox account. If you don't remember your Cox account password, go to cox.net and click "Sign In," then click "Forgot Password?" below the login fields.
Cox will ask you to enter your account username (usually your email address) and will send a password reset link to that email. Click the link, create a new Cox account password, and then you can proceed with changing your WiFi password using the steps above.
This process usually takes a few minutes. If you don't see the reset email in your inbox, check your spam or junk folder, or wait a few minutes and request a new link.
Your WiFi password versus your Cox account password
These are two separate passwords that do different things. Your Cox account password is what you use to log into cox.net and manage your bill, services, and account details. Your WiFi password is what you and your guests use to connect devices to your home internet.
Changing your WiFi password does not change your Cox account password, and changing your Cox account password does not change your WiFi password. If you want to change both, you'll need to do each one separately.
Your WiFi password is visible to anyone in range of your network, so changing it regularly is a good security practice. Your Cox account password should be changed less frequently but should be strong and unique to your Cox account.
Troubleshooting: what to do if the change doesn't work
If you see an error message when trying to save your new WiFi password, the most common cause is that your password doesn't meet Cox's requirements. Make sure it's at least 8 characters long and includes uppercase letters, lowercase letters, numbers, and at least one special character. Try removing any spaces or unusual symbols and try again.
If the website or app seems frozen or won't load your modem settings, try logging out completely and logging back in. Clear your browser's cache if you're using the website, or close and reopen the Cox app if you're using the mobile version.
If you're still unable to change the password after trying these steps, contact Cox customer service at 1-800-234-3993. They can verify your account and help you change the password over the phone or troubleshoot any technical issues with your modem.
Frequently Asked Questions
How often should I change my WiFi password?
There's no strict rule, but changing it every few months is reasonable if you want to maintain security. Change it when ready if you think someone has accessed your network without permission, or if you've shared it with a guest who no longer needs access.
Will changing my WiFi password affect my internet speed?
No. Your WiFi password only controls who can connect to your network — it has no effect on your internet speed or the performance of your connection once devices are connected.
Can I change my WiFi password from my phone if I'm not home?
Yes. As long as you're connected to your Cox WiFi network or have mobile data, you can use the Cox mobile app to change your password from anywhere. You'll just need to remember your Cox account password.
What if I change my password and then forget the new one?
Log back into cox.net with your Cox account credentials, go to your modem settings, and change the password again to something you'll remember. There's no way to view your current WiFi password through the Cox website or app — you can only change it.
Do I need to restart my modem after changing the password?
No. The password change takes effect when ready without a restart. Your modem will continue working normally, and devices will straightforward need to reconnect using the new password.
