Ubuntu Networking :: Setting Up Server Access Point With Wg311(v1)

Ive spent the last couple of days looking for a way to set this up and cant find the solution anywhere. Right from what iv read so far i understand i have to set the card to master mode but when i try

Code:

sudo iwconfig wlan0 mode master

i get the error

Code:

Error for wireless request "Set Mode" (8B06) : SET failed on device wlan0 ; Invalid argument.I read somewhere that the madwifi driver is up to the task but im still quite new to linux and not really sure how to change the drivers. this is what iv done so far

Code:

wget http://snapshots.madwifi-project.org/madwifi-trunk-current.tar.gz
tar xvxf madwifi-trunk-current.tar.gz
cd madwifi-trunk-r4108-20100115/
sudo make

[code].....
