i am trying to connect my raspberry pi model B to the internet using the ethernet port to my BT home hub. when i turn the pi on, 2 extra lights are illuminated on its circuit board. so i know that it is connected. but then when i try to open the web browser, it comes up with a message and doesn't do anything else. i am using the NetSurf browser. i am wondering if it is the password on the hub. i know it, but i dont know how to imput it. do you need to? help as soon as possible, please.
