How to enable WPA with Ndiswrapper driver

• First, make sure the Ndiswrapper driver works by itself without encryption.

• Create a file called /etc/wpa_supplicant.conf, and paste in the following. Modify the ssid and psk values.

ctrl_interface=/var/run/wpa_supplicant
network={
  ssid="YourWiFiSSID"
  psk="YourWiFiPassword"
  key_mgmt=WPA-PSK
  proto=WPA
  pairwise=TKIP
}

• Test it. Make sure your router is broadcasting its SSID.

sudo wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd

• If your WPA works. Load it automatically when you reboot.

gksudo gedit /etc/network/interfaces

• Change your wlan0 section to the following.

If you are using static IP:

auto wlan0
iface wlan0 inet static
address 192.168.1.20
netmask 255.255.255.0
gateway 192.168.1.1
pre-up wpa_supplicant -Bw -Dwext -iwlan0 -c/etc/wpa_supplicant.conf
post-down killall -q wpa_supplicant

or this, if you are using dhcp.

auto wlan0
iface wlan0 inet dhcp
pre-up wpa_supplicant -Bw -Dwext -iwlan0 -c/etc/wpa_supplicant.conf
post-down killall -q wpa_supplicant

• Reboot
