All BT Broadband customers are automatically opted-in to BT Wi-fi and its worldwide partner FON. It means that those customers have unlimited and free wi-fi access at any BT Wi-fi hotspot in the UK and FON site worldwide. In return the broadband user shares a very small amount of their unused bandwidth with other BT Wi-fi users.
Non-BT broadband customers can purchase wi-fi access.
The BT Homehub will allocate a maximum of 5 IP addresses to BT Wi-fi users. Speeds available to BT Wi-fi users is limited to the range of 512k to 5Mb/s depending on the line speed of the broadband connection. The broadband user has bandwidth priority over wi-fi connections. Wi-fi users will be disconnected if the broadband customer requires their full bandwidth.
A BT Broadband customer can opt out of FON anytime they want by visiting the
BT | FON website. Once opted out they can no longer use the free wi-fi service at hotspots. It can take up to 30 days for BT to send a software update to the HomeHub so don't expect the BT Wi-fi signals from your HomeHub to disappear immediately.
