How to Change Your Wi-Fi Name and Password on Your Router

You want to rename your home Wi-Fi (the SSID) or set a fresh password — usually after sharing the old one too widely or to make the name easier to recognize.

Why: Both live on the router’s admin page under Wireless settings, not in Windows. Changing them there pushes the new name/password to every device — so after you save, each device has to reconnect with the new details.

Step 1: Open the router’s wireless settings

1. Open your router’s admin page in a browser. For TP-Link, go to http://tplinkwifi.net or http://192.168.0.1 and sign in. (Not sure of the address? Run ipconfig and use the Default Gateway.)
2. Go to Advanced → Wireless → Wireless Settings.

Step 2: Change the name (SSID) and password

1. In the Network Name (SSID) box, type the new Wi-Fi name. Keep it recognizable but avoid personal info like your full name or unit number.
2. In the Password box, type a new Wi-Fi password. It’s case-sensitive — make it at least 12 characters.
3. For Security, choose WPA2-PSK (AES) or WPA3-Personal/WPA2-PSK if your router offers it.

If your router broadcasts separate 2.4 GHz and 5 GHz networks, repeat for each band (or give them the same name to roam automatically).

Step 3: Save and reconnect

1. Click Save. If you made the change over Wi-Fi, your device disconnects the moment the new credentials apply — that’s expected.
2. On each device, pick the network and enter the new password. On Windows, if it tries the old password, go to Settings → Network & internet → Wi-Fi → Manage known networks → Forget, then reconnect.

FAQ

Will this change my router’s admin login too? No. The Wi-Fi password and the admin (login) password are separate — this changes only the Wi-Fi one.

Do I have to redo every device? Yes — phones, laptops, TVs, smart plugs all need the new password once. That’s normal after any Wi-Fi password change.

My laptop keeps using the old password. Forget the network in Windows (above) so it stops auto-filling the stale one, then reconnect.
