MY-WF003U
USB Wi-Fi Module
4.5.2 using the command line configuration
Boot wpa_supplicant:
# wpa_supplicant -i wlan0 -c/etc/wpa_supplicant.conf -Dwext -B
If the prompt does not support
“-Dwext”, delete it.
Scan wireless network:
# wpa_cli -p/var/run/wpa_supplicant scan
Indicate the found wireless network:
# wpa_cli -p/var/run/wpa_supplicant scan_results
Add to one network and please note the returned network ID which will be used for ssid and psk
settings. Here the returned value is
“20”:
# wpa_cli -p/var/run/wpa_supplicant add_network
Selected interface 'wlan0'
20
Set the ssid of the network, here we use
“MYIR”:
# wpa_cli -p/var/run/wpa_supplicant set_network 20 ssid ‘‚MYIR‛’
Set the psk of the network, here we use
“123456”:
# wpa_cli -p/var/run/wpa_supplicant set_network 20 psk ‘‚123456‛’
Select network:
# wpa_cli -p/var/run/wpa_supplicant select_network 20
If not got IP address of wlan0, use below command to get IP address:
# udhcpc -i wlan0
After above steps,
get online through WiFi.
# ping www.baidu.com
