New Harddrive... now no wireless???

The wireless card that came with my Inspiron B120 is no longer being recognized in my computer. Now instead of when it used to say "Wireless Connections", it just says Broadband and LAN or High-Speed connection. This is driving me insane! Why is it doing this? Do I need to install something to re-recognize it? Oh, this started happening as soon as I got my new harddrive. Why does the Broadband connection ask me for a username and password? I've never set one up... Please help, ASAP! Kinko's is expensive to sit at. Thanks!
