Draft N USB wireless

[Janardana Deva]

Are there any Linux Drivers for Draft N interfaces?
If yes, for what brands/models?

The closest I got to a supported draft n device (BCM43xx, which
is supposed to support draft N) in linux is this writeup at http://en.opensuse.org/SDB:Broadcom_(BCM4306)_WLAN_Installation_under_SUSE:

 openSUSE 10.2 Option 1 - Original Driver Procedure 
On an HP Pavilion zv6000 laptop the driver configures
automatically on a fresh install but is not funcional; the BIOS still
reads that the card is enabled but if you watch the boot messages
you'll see a line saying radio is disabled. The 1-touch-button for
enable/disable wireless is off and pushing the button or using
KWifiManager does not remedy the problem. Installing bcm43xx-fwcutter
firmware will fix this problem.

1. You need to check if the bcm43xx-fwcutter package is installed
through: Yast > Software > Software Installation and search for
bcm43xx-fwcutter
2. Find the windows driver for your wireless chip. An example
windows driver was titled bcmwl5.sys Also note if you can't find yours
try doing a google search for wl_apsta.o (SUSE worked with both the
orginal windows driver and the wl_apsta.o at the time of this WIKI
post). Put the driver file on your desktop in SUSE.
3. Start the shell console (Kmenu >System > Terminal Program > Terminal) and login as root with the command:

sux -

and type in the root password
Extract your firmware files from your wireless chip and store
them in the firmware file by typing in the following. (Note: Swap out
the name of your driver accordingly...in this example it is
wl_apsta.o):

 bcm43xx-fwcutter -w /lib/firmware ~/Desktop/wl_apsta.o

4. Another way to install the firmware is using the install script
included in the bcm43xx-fwcutter package. You need to have a working
internet connection for this as it is attempted to download wl_apsta.o,
next the firmware is extracted and stored in /lib/firmware.

 install_bcm43xx_firmware 

5. Now that the firmware is ready for the driver to use, load the module by typing the following:

 modprobe bcm43xx

6. Reboot and now you can configure your WLAN card through YAST > Network devices > Network card
