wireless

I have recently set up ubuntu 12.04 on my laptop using the Wubi installer. I am having a very difficult time setting up a wireless internet connection. I am currently set up with an ethernet connection which I have used to download all new updates and to activate the Broadcom STA wireless driver.

I have tried several things in the terminal based on other people's posts:

~$ rfkill list 0: brcmwl-0: Wireless LAN Soft blocked: no Hard blocked: yes
~$ rfkill unblock all

It doesn't change anything. I also tried rebooting and connecting to the internet on my Windows Vista OS, and it worked, so I know that the connection should not be hard blocked. I have also tried installing b43 firmware (lp/phy version) that is supposed to work with my chip (BCM4312). It seems to have no effect.

Then I tried:
~$ iwconfig lo no wireless extensions.



eth1      IEEE 802.11  Access Point: Not-Associated  

         Link Quality:5  Signal level:0  Noise level:0 

          Rx invalid nwid:0  invalid crypt:0  invalid misc:0

eth0 no wireless extensions.

This is my first time trying to work with ubuntu, so I would appreciate any help. Thanks.

Also sorry this is poorly formatted. I'm having troubles with that too.
