I have been trying to configure the wireless settings at my friends place for a few days now and today I finally got it.
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
network={
proto=WPA
mode=0
key_mgmt=WPA-PSK
ssid="theSSID"
psk="thePassword"
The problem was that I was trying to configure it as WPA2 because in the Intel PROSet/Wireless configuration it stated that it was “WPA2-Personal” as the Network Authentication type. It was only after I tried using the Microsoft Wireless configuration that enables me to select the wireless access point (WAP) and then input the keyphrase that I realised it was WPA. Strange. Must be the SMC wireless router or something…
