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.
