..but my WiFi works fine.

In Windows I had to install Dell Wirless 365 Bluetooth driver to get it working. I installed BlueMan in Ubuntu, but it doesn't show any Bluetooth adapter. When I try to apply a kernel patch described here , it ends up saying:

patching file src/wl/sys/wl_linux.c

Hunk #1 FAILED at 332.

1 out of 1 hunk FAILED -- saving rejects to file src/wl/sys/wl_linux.c.rej

Thanks for any help...

I had the same problem on my dual boot machine, switching over to windows and enabling the bluetooth and then going back to Ubuntu 12.04 fixed the problem.
