Is the bluetooth adapter built-in to the laptop, or as it seems, are you using a usb bluetooth adapter that you plugin? What is the model of bluetooth adapter? Have you also tried installing the "blueman" package from the Ubuntu Software Center? Also, do you actually have Ubuntu installed to the hard drive, or are you operating it from a USB-Flash-Stick?

Now my bluetooth is working. I try reinstall

sudo apt-get install --reinstall linux-headers-generic build-essential

After that, compile and install the driver as follows -
1) Download the latest backported driver package from here - http://drvbp1.linux-foundation.org/~...tml/backports/
2) Copy the downloaded tar.bz2 package to your Ubuntu Desktop > Right-click > Extract here.
3) Open a terminal and run the following commands one-by-one

cd Desktop/backports-3.18-rc1-1
make defconfig-ath9k
make
sudo make install

4) Reboot for the newer driver to take effect.

Now Solved. Thank you bro

I just attempted this fix. Upon reboot, bluetooth is not fixed and now my wireless doesn't work. Also, while booting I get an error message that says "failed to load module iwldvm". How do I revert back to what I had before?

I know it is a bit too late but:

1- Navigate to the backport folder
2- sudo make uninstall
3- sudo reboot
