Changing the Wi-Fi password disconnects devices that use the old password, so plan to reconnect them afterward.
Steps
- Log in to the router administration page.
- Open Wireless, Wi-Fi, WLAN, or Security settings.
- Select WPA2-Personal or WPA3-Personal when supported.
- Enter a long, unique passphrase and save the change.
- Reconnect each trusted device using the new password.
Password guidance
Use at least 14 characters and avoid names, addresses, phone numbers, or reused account passwords. Store it in a trusted password manager.
Plan the change before saving it
Changing How to Change Your Wi-Fi Password can disconnect every wireless client. Record the current settings, choose the new value and update critical devices first. Smart-home products may require manual reconnection, and a device can retain an old network profile even when the visible name looks similar.
How to confirm success
Reconnect one phone or computer, verify it receives a valid local address and test both local gateway access and Internet service. Then update other devices. If the old network name remains visible, confirm whether a mesh node, extender or ISP gateway is still broadcasting it.
