Hi, philip.stefanov, and welcome to the forum :slight_smile:

Your adapter needs the “wl” (WL) driver for its Broadcom chip, but as it’s a source code package, it needs the kernel source (or at least the headers) to compile …

Make sure you’re connected to the internet by a wired (ethernet) connection to your router, then open a terminal (Crl+Alt+T) and run these 2 commands:

sudo apt-get install --reinstall linux-headers-generic build-essential dkms bcmwl-kernel-source

then when that’s finished:

sudo modprobe wl

Your wireless should now spring to life … if it does but doesn’t survive a reboot, let us know and we’ll tell you how to load the wl driver at bootup.

If that doesn’t work … is 3.5.0-17-generic the default kernel for Ubuntu 12.10 ? … if not, how did you install it ?

Working like a charm
Thank you 8)
