debian安装wifi

from https://wiki.debian.org/wl

Installation

1. Add a "non-free" component to /etc/apt/sources.list for your Debian version, for example:

   # Debian 8 "Jessie"
   deb http://httpredir.debian.org/debian/ jessie main contrib non-free

2. Update the list of available packages. Install the relevant/latest linux-image, linux-headers and broadcom-sta-dkms packages:

   # apt-get update
   # apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms

   This will also install the recommended wireless-tools package. DKMS will build the wl module for your system.

3. Unload conflicting modules:

   # modprobe -r b44 b43 b43legacy ssb brcmsmac bcma

4. Load the wl module:

   # modprobe wl

5. Configure your wireless interface as appropriate. See also known issues.
