USB WiFi Dongle

Sun Mar 17, 2013 11:06 am

Hey,

I'm running Raspbian “wheezy” on my new Raspberry Pi, but am having some trouble setting it up. I have two USB WiFi adapters to try, the GetNet GN-621U (RTL8191SU) and the ZyXel G-202, however none of the online guides I can find seem to help and I cannot get either of the adapters to work.

The GetNet GN-621U specifies Linux compatibility on the box, so I assume this should be the easiest of the two to set up.

The RTL8xxx Chipset is well supported in the latest and fully updated / upgraded Debian "wheezy" and this
question has been asked /answered many many many times,


Plug the USB WiFi Dongle, into a Powered USB Hub if avaiable, otherwise into the Pi's USB Port and boot
up Raspbian "wheezy".

The N Dongles may take too much power plugged into the Pi

You need to go into LXTerminal from Desktop or logout to Command Line and type lsusb and press enter,
this will state whether or not the device has been recognised.

If it is recognised on the desktop launch the WPA Config application and follow instructions..................

I believe the wireless encryption should be set to ccmp and not tkip in the wpa configuration.
I will always assume you are running Raspbian for desktop and Raspbmc for XMBC !

SOLVED:

Here's How:

Code: Select all

sudo nano /etc/wpa.config
Type in:
network={
ssid=”YOUR_SSID”
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk=”YOUR_WIFI_PASSWORD”
}

Code: Select all

sudo nano /etc/network/interfaces
Type in:
auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
auto wlan0
iface wlan0 inet dhcp
wpa-ssid “YOUR_SSID”
wpa-psk “YOUR_WIFI_PASSWORD”

Then to restart:

Code: Select all

sudo /etc/init.d/networking restart

It took a while, but it eventually connected to my WiFi without any errors.

sometimes you have to shutdown your eth0 to get wlan0 working properly. i wrote up a quick guide to help others because i had to search around a bit to get mine up and working properly.

here it is. hope it helps...
