We recommend turning off all security first, testing the arduino to make sure it’s not defective.
Connect to your Linksys router by typing in 192.168.0.1 to your browser. Default settings are username:admin and an empty password.
Wireless Settings -> Manual Wireless Connection Setup
Wireless Network Name : no spaces or special characters
Wireless Security Mode: WPA-Personal
WPA Mode: WPA2 Only
Cipher Type: AES (Apperently the shield doesn’t work with WPA2 and TKIP)
Group Key Update Interval: 3600 seconds
Pre-Shared Key: no spaces or special characters
You can find your channel on the status page. We didn’t need this to set up the Wifly.
Testing your wireless network with Wifly shield
Add https://github.com/sparkfun/WiFly-Shield/tree/master/Libraries to your Arduino Library (unzip the Library, go to Arduino application, Sketch->Import Library->Add Library and go to where you unzipped the library, open the main parent folder, restart your Adruino application)
Open the SpiUartTerminal sketch (File->Examples->Wi_Fly-Shield->SpiUartTerminal)
Upload the sketch and open Serial Monitor (Tools->Serial Monitor)
type $$$ (make sure no line ending is selected)
select carriage return
type get wlan (these are the current settings)
type set wlan ssid wireless$network$name ($ is used instead of spaces, your wireless network shouldn’t have spaces anyway)
type set wlan phrase wirless$password
type join (it will either give you an error or tell you it’s successfully connected)
type save if everything worked properly
Congrats! You have wireless capabilities.
Now add the wireless settings to the appropriate Credentials.h
We had to comment out skipRemainderOfResponse(); in the boolean WiFlyDevice::join(const char *ssid) of WiFly_Shield/WiFlyDevice.cpp because it was hanging (it couldn’t find a new line to know when the response had ended).
