[ubuntu] HP touchsmart tx2 wireless switch is off

view story

http://ubuntuforums.org – Hi, I'm really new to linux so I decided to try ubuntu 12.10 on my old HP touchsmart tx2 laptop. One big problem is the wireless switch (light) is off doesn't turn when I turn it. I did some research and found some solution but I live in a dorm so I can't go plug my laptop to a router with ethernet cable. Is there anything I can do to fix this? I really like it but I don't have an internet access :(. Thank you (Hardware)
