My MacOSX Lion does not automatically connect to BT Hub4 Internet - Why

My MacOSX Lion 10.7.5 laptop is registered to connect with my BT Hub 4 unit. When I switch on the computer it does not automatically connect to

the network. I then have to go through the setup process to enable me to connect to the internet.

Also, when I use mu samsung tablet to connect to the same BT4 Hub there is not a problem. Can you help me ?
