I'm not able to enable Wireless using the hardware switch -f12- on my HP Pavilion dv6-7080-se.

the Enable Wireless option is greyd out so I cannot enable it.

while starting ubuntu when i press f12 -which starts wifi drive- for a login time the wifi works.

The results of iwconfig for my system are as follows

eth0      no wireless extensions.

eth1      IEEE 802.11abg  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:on

lo        no wireless extensions.

the result of rfkill list all for my system is as follows 1

    Soft blocked: no
    Hard blocked: yes

Try

sudo rfkill unblock all

then

sudo ifconfig eth1 up

It should turn you wifi on.

Broadcom wirless does not work properly on Ubuntu. This post may help you. Also make sure that you have not turned off you wireless from BIOS menu. –  Guru Feb 20 at 10:29

Same problem with HP Pavilion dv5 and Mint 16 Petra. What worked for me was to reset BIOS to factory defaults. There appears to be no other way to access wifi in BIOS and touching wifi antenna to turn it to blue on state at boot did not work although it works for windows.
