As default, Ubuntu GNU / Linux doesn't support broadcomm WLAN (WiFi) adapter. And so, if you have laptop / netbook with broadcomm adapter, you won't be able to connect to the internet throughout WiFi / hotspot connection. But luckily, Ubuntu makes it very easy to install broadcomm WLAN adapter. There are two easy options to install it : 1. By APT Plug your laptop in to a wired (cable) internet connection and install the driver by following command : sudo apt-get install bcmwl-kernel-source 2. By Ubuntu Live CD / USB In your Ubuntu Live CD / Live USB, find a folder named pool. Find these files : - pool/restricted/b/bcmwl/bcmwl-kernel-source.xxx.deb - pool/main/d/dkms/dkms_xxx.deb - pool/main/f/fakeroot/fakeroot_xxx.deb - pool/main/f/fakeroot/libfakeroot_xxx.deb Copy those files into your home, open terminal, and install them by following command : sudo dpkg -i *.deb And now, you will have your broadcomm WLAN / WiFi works.
