How to Setup Asus USB N10 Wifi Adapter On Raspberry Pi

BEFORE WE BEGIN:

• There are numerous approaches to accomplish a task with Linux. However, the method described below is the one that proved successful for me.

• The image I utilized was Wheezy-Raspian (2012-09-18), which comes with the required driver/module already installed. To verify this, you can enter the command “lsmod | grep r8712u” and the expected output should resemble: “r8712u 165407 0”.

• To enable it to function properly, we need to modify two files, namely interfaces and wpa_supplicant.conf.

• Since I utilized PuTTY to SSH into my Raspberry Pi and perform the configurations, the appearance of the interface is not identical to the LXTerminal (as seen in all images below).
  

Step 1: 

From an SSH session or terminal on your Pi, issue the following command to your RaspberryPi to update it:

sudo apt-get update

Step 2:

Then issue the following command to edit the network interface file of the Wheezy-Raspian OS:

sudo nano /etc/network/interfaces

Then append the following configuration as seen in image below.

After appending the new configuration, press the following keys in this order to save configuration:

ctrl + x (at above screen)

Then, Y (at above screen)

Finally, enter key (at above screen)

Step 3:

Then issue the following command to edit wpa_supplicant.conf file:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Then appended the configuration (as seen on image below):

Repeat the step previously mentioned to save the configuration.  Reboot your Raspberry Pi to complete the step and then test out your newly configured WiFi.  USB WiFi dongle should be continuously blinking, this means configuration was setup successfully.  DONE!

For Your Information:

#If you are finding that your wifi dongle does not reconnect to your wifi network after your Raspberry Pi reboots  add:

auto wlan0

into the /etc/network/interfaces

More FYI:

SSID:   <Is your home Wi-Fi name>

Scan_ssid:  

• Set value to 1 if you are trying to connect to hidden network or if you have more than one wireless access point: each with different SSID.  I suggest you enter value of 1.
• Alternatively, set value of 0 will do the opposite of value 1 (for home networks that broadcasts SSID)

PSK:   <Your wifi password>

PROTO:   your choice of RSN or WPA. RSN is WP2 and WPA is WPA1. (Most config is RSN)

Key_mgmt:   your choice of WPA-PSK or WPA-EAP (pre-shared or enterprise respectively)

Pairwise:   your choice of CCMP or TKIP (WPA2 or WPA1 respectively)

Auth_alg:   OPEN option is required for WPA and WPA2 (other option, SHARED & LEAP)
