How to Find the WEP Key on BT Broadband

Updated July 20, 2017

Protecting your home wireless network from intruders is a vital step in protecting your computer's security. BT Broadband, the ADSL Internet service from British telecommunications company BT, allows you to utilise one of two types of wireless security: Wi-Fi Protected Access (WPA), or Wired Equivalent Privacy (WEP). WPA, the new industry standard wireless protection protocol, has increased security capabilities over Wired Equivalent Privacy (WEP) so by default, newer routers are set to WPA. However, you can switch to WEP and change the security key if you prefer.

Open the Hub Manager. If you don't know how to access this, go to the BT Home Hub security page and click "Click here to open your Hub Manager."

Enter your serial number and admin password (both are found on the back of your BT Home Hub router). You will then be prompted to set up an administrator password. Enter your preferred password, confirm it then click "Change password and Open Hub Manager."

Log in with your new chosen password, then click "OK."

Click "Use WEP" next to "Encryption," then change the "WEP Key Length" to "128 bit" from the drop-down menu.

Enter your new preferred WEP Encryption key in the box provided. This password must be 26 characters in length, containing upper and lower case letters (between A and F) and numbers between 0 and 9.

Make a note of your new WEP key.

Click "Apply" to save changes. When your wireless device connects to the BT Home Hub you will now be prompted to enter the WEP key. Enter your preferred key to log in to the network.


Newer BT Home Hub routers will automatically have WPA set-up. A hard copy of your wireless key will be on a card included with your original documentation called "BT Home Hub wireless settings.". Alternatively, unplug your router, slide out the bottom panel on the back and your wireless settings key will be printed there as well. This is the default key only and will not change if you manually change the password.
