How do I change the wi-fi password on my BT Hub
Your BT Hub’s wi-fi is protected by a password that stops anyone getting unauthorised access. You’ll find the password on your Hub’s settings card. Find out where to look for your wi-fi settings >
We don’t recommend changing the password because the one we give you is already very secure. However if you’d still like to change it, click on the dropdown for your model of Hub.
BT Smart Hub 2:
You can change the wi-fi password via the My BT app.
Begin by opening the My BT app and select Home Network.
Next, select Settings, then select Network settings.
Now select Change Wi-Fi password and enter the current Wi-Fi password.
The final step is to simply enter and confirm the new Wi-Fi password.
BT Smart Hub and Ultrafast Smart Hub:
Begin by opening a new web browser on a device connected to your Hub and type 192.168.1.254 in the address bar to open the Hub manager.
The next step is to click Advanced Settings, then Wireless.
Now enter the admin password – unless this has previously been changed it, you can find the default password on the Hub settings card on the back of the BT Broadband Hub.
If this has already been changed and forgotten, you can use the password override feature to set up a new password without losing all your personal Hub settings and configuration.
To change your wireless key, overtype the existing Security Password with a password of your choice.
Security experts urge users to make the password as secure as possible it needs to be between 12-63 characters, a combination of uppercase, lower case letters and numbers.
