Raspberry Pi with RTL8188CUS 802.11n wifi adapter – Update

I’ve actually been playing around with my Realtek RTL8188CUS wifi adapter and found that the configuration of the wifi adapter without wpa_supplicant seems to be a better way to go.

The information I found below was taken directly from the source Far Robotics Website. Thanks to those folks for posting the 3 methods below;

Installing rtl8188cus and rtl8188eu based wifi adaptors for raspbian without using wpa_supplicant.

Edit the file /etc/network/interfaces using the following format for networks with WPA/WPA2 security. Use the command sudo nano /etc/network/interfaces to open and edit the file. Exit the editor and save the file using keys cntl-X, Y, Enter.  Enclose Your-Network-Name and Your-Network-Password within quotation marks as in the example below.

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-ssid "Your-Network-Name"
wpa-psk "Your-Network-Password"

Edit the file /etc/network/interfaces using the following format for networks using WEP security. Use the command sudo nano /etc/network/interfaces to open and edit the file. Exit the editor and save the file using keys cntl-X, Y, Enter. Do not use quotation marks around Your-Network-Name and Your-Network-Password.

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet dhcp
wireless-essid Your-Network-Name
wireless-key Your-Network-Password

Edit the file /etc/network/interfaces using the following format for networks using no security. Use the  command sudo nano /etc/network/interfaces to open and edit the file. Exit the editor and save the file using keys cntl-X, Y, Enter. Do not use quotation marks around Your-Network-Name.

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet dhcp
wireless-essid Your-Network-Name

If you have success and/or failure, be sure to post a comment. Feedback is always most welcome.

    Thanks for the write up. Been looking for an hour for a solution to connect the Netis WF2111 usb wifi dongle to Raspbian. The default WIFI Config gui does not work and the default lines using wpa_supplicant failed as well. Put in the lines above and it fired right up.
