WI-PI: WI-PI WLAN Installation Procedure for Raspbian on Raspberry Pi

I tried to edit my las comment but it did not work, however.

I fixed the problem by adding

wireless-essid <MY_ESSID>

after the line iface wlan0 inet dhcp

No need to run additional commands after boot. It now comes up with an IP address.

I followed the instructions exactly as stated in the documentation

auto wlan0

iface wlan0 inet dhcp

wpa-ssid <name of your WiFi network>

wpa-psk <password of your WiFi network>

I removed the wpa_supplicant.conf called by the wpa-roam

On reboot no IP address

I looked at the iwconfig output and noticed that my essid was not there although you can see it was in my interfaces file above.

Entering the following commands:

sudo iwconfig wlan0 essid "MY_ESSID"

sudo dhclient -1 wlan0

I now have an IP address

The difference between mine and a normal setup is I am security minded and my AP does not broadcast its essid or ssid if you like.

For some reason the ssid does not get added to the wlan0 on boot.

Anyone who has this problem, I would like to find out how it can be fixed.

Also, why on this earth would anyone assume a broadcast essid for home use when writing connection instructions?

The previous instructions stopped working for me and the configuration method has changed (see below). The interfaces file now refers to wpa_supplicant.conf file for setup info. Setting up the two files as shown below works for me.

WiPi Installation

File: /etc/network/interfaces: Network configuration file.

The following is a copy of the interfaces file from a SD card on which the wi-pi works:

pi@raspberrypi ~ $ sudo nano /etc/network/interfaces

GNU nano 2.2.6 File: /etc/network/interfaces

Make sure the /etc/network/interfaces file contains the following:

auto lo

iface lo inet loopback

iface eth0 inet dhcp

allow-hotplug wlan0

iface wlan0 inet manual

wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

iface default inet dhcp

pi@raspberrypi ~ $ sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

GNU nano 2.2.6 File: /etc/wpa_supplicant/wpa_supplicant.conf

Make sure the /etc/wpa_supplicant/wpa_supplicant.conf file contains the following:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

update_config=1

network={

ssid="your AP ssid"

psk="your AP password"

proto=WPA

key_mgmt=WPA-PSK

pairwise=TKIP

auth_alg=OPEN

}

Reboot the rPi : sudo reboot

WiPi hopefully will be working when rPi restarts.

I found the manual very clear and useful but when I launched the desktop after updating on the initial boot I found a Scan function was in fact available for Wi-Pi.  I had somehow edited the config file incorrectly and did not at first get wi-fi but using the Scan GUI corrected everything for me at once.  It seems though that manually editing the config file may no longer be necessary, at least if you use the desktop.
