[ubuntu] Proprietary wireless driver problems

view full story

http://ubuntuforums.org – I'm trying to install Ubuntu 12.04 on a HP Pavilion dm1 from usb. While connecting to my wireless modem the proprietary drivers warning showed up. I went to System Settings->Additional Drivers and what every site I read told me to do next is to click the "Activate button" which I can't see because the green light is on and "This driver is activated and currently in use" is on the buttons place. I can see he's trying to connect, but failed every time. It is a Broadcom STA wireless driver. (Hardware)
