Access point: Not-Associated
indicates that we are not currently connected to an access
point
19.
At this point you can
scan to show any
networks that are in
range by using the
iwlist wlan0 scan
command.
This will show a list containing all WiFi points in range. Each entry is numbered from cell 01
onwards and will show information for each connection such as the SSID and the encryption
key status (Android and WPA2 in this case)
20.
Edit the file wpa_supplicant to provide the SSID
and PSK of the network you wish to connect to. To
do this you can enter
vi
/etc/wpa_supplicant.conf
and edit the file to
look as below (substituting
YOUR_SSID
and
YOUR_PSK
for the appropriate values)
21.
Now initialise the WiFi
connection with the
following command:
wpa_supplicant –B –
D wext -1 wlan0 –c
/etc/wpa_supplicant
.conf
The error message about RFKILL is nothing to be worried about as it is used for hard-
switches that block different types of RF radios and we do not use this functionality
22.
Get an address from the DHCP server using the
command
udhpc –i wlan0
The Xplained board has been assigned an IP Address (192.168.43.1 in this case)
