Since I’m constantly moving large files around my network which seem to take forever on my ancient Laptop that only supports wireless b/g, I decided to invest in an Edimax EN-7811Un Wireless N adapter to take advantage of my Wireless N capable Cisco887W Router. Unfortunately however, I quickly discovered that Ubuntu 10.04 does not natively support the Edimax wireless device even running the latest 10.04 Kernel 2.6.32-36 (as of 05-12-2011) and I would need to manually install the Linux driver myself.

The first thing you will need to do, is identify your current built-in wireless device (if any):
lspci -k (Take note of the module being used)
There is an excellent guide located here which you can use to help identify your hardware and corresponding driver modules if you need help:

Then you will need to disable/blacklist the module from being loaded:
sudo nano /etc/modprobe.d/blacklist.conf
#Blacklist built in wifi
blacklist ipw2200 (module name)

Then install the drivers:
sudo apt-get install build-essential
cd to extracted drivers directory
make
sudo make install
sudo modprobe 8192cu

Whenever an updated kernel is installed, you will need to rebuild the driver module again from source for the new kernel.
cd to extracted drivers directory
make clean
make
sudo make install
sudo modprobe 8192cu
