How to setup a Raspberry Pi with a hidden network using a Edimax EW-7811Un
If you are looking for a wireless adapter for the Raspberry Pi, the Edimax EW-7811Un is reasonably priced at $12.99 ($9.99 w/ Amazon Prime) and is supported with Raspbian "wheezy" 3.2.27+ kernel. There were driver issues with earlier versions of Raspbian, but luckily you won't have to worry about installing drivers with any Raspbian image dated 2012-12-06 or older.
After you install Raspbian to a SD card, boot up the Raspberry Pi and perform the following:
Launch a repository update
sudo apt-get update
Run a system upgrade
sudo apt-get upgrade
Make sure that the latest Raspberry Pi firmware version is installed
sudo apt-get install raspberrypi-bootloader
Install the wpa_supplicant utility
apt-get install wpasupplicant
WLAN setup and configuration for a hidden SSID wifi network
Generate a PSK version of your WLAN password with wpa_passphrase utility
wpa_passphrase "<Your Wifi SSID>" "<Your Wifi PASSWORD>"
(Quotes are needed for whitespace)
Edit
sudo nano /etc/network/interfaces
and add the following:
######################################
auto lo
iface lo inet loopback
iface eth0 inet dhcp
auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-scan-ssid 1
wpa-ap-scan 1
wpa-key-mgmt WPA-PSK
wpa-proto RSN WPA
wpa-pairwise CCMP TKIP
wpa-group CCMP TKIP
wpa-ssid "<Your Wifi SSID>"
wpa-psk <Your PSK Value>
iface default inet dhcp
######################################
Save the changes and shutdown the Raspberry Pi.
Unplug the ethernet cable and plug in the Edimax EW-7811Un wifi dongle.
Power on the Raspberry PI and wait for the wireless to get a IP.
My router statically maps a IP to the network interfaces MAC address, that is why I chose to allow Linux to run DHCP.
