I bought a wifly shield from sparkfun, and aim to use it post sensor information to the internet.

But the problem is getting the Wifly to connect to a network. When using SpiUartermial example from wifly library I can connect to the network by doing the following in the serial monitor:
set wlan phrase mypassword
join myssid

I then check that I am connected using:

show net

And I am connected.
However when saved and reboot the information is lost. Following this guide http://www.mgisolutions.info/2012/05/arduino-wifly-shield-tutorial.html with additional settings from the data sheet http://www.sparkfun.com/datasheets/Wireless/WiFi/WiFlyGSX-um2.pdf I put the following commands through the serial monitor:
set ip dhcp 0
set ip address
set ip netmask
set wlan join 4
set wlan ssid myssid  Its a virgin media hub if that changes anything
set wlan auth 4 WAP2 auth used
set wlan chan 11
set wlan phrase mypassword

Then when I check connection  its not connected.

Its very frustrating as I can't move on with the project. I think I would prefer it if it didn't connect either way, then it would be less frustrating.

I have tried doing different dhcp settings, as well as copying ip/netmask/chan shown when connected through the first method.

I hope that is enough information, and I have done hours of internet trawling and can't find the solution.


In one case you use:
set wlan phrase mypassword

and in the other you use: 
set wlan mypassword

Could that be the problem?

Sorry that was a typo in the message, I have now edited the initial post. I have now managed to get connected to a network by changing the join option to option 1. I have also managed to mash together code to set the WiFly up in code without using the Spiuart terminal with manual inputs.

How ever I now have another problem, I can't seem to get the WiFly example for a web client to work. The code i am using is:

Code: [Select]
#include "WiFly.h"

Client client("google.com", 80);

void setup() {


  if (client.connect()) {
    client.println("GET /search?q=arduino HTTP/1.0");
  } else {
    Serial.println("connection failed");
   Serial.println("End of setup.");

void loop() {
  Serial.println("Start of void loop");
  if (client.available()) {
    char c = client.read();
  if (!client.connected()) {
  Serial.println("End of void loop");

Using the serial prints I can tell that it hangs at the if (client.connect() statement. Hopefully I have provided enough information for someone to be able to shed some light on the problem. I have tried several suggestions on other web client examples and still doesn't work.

EDIT: Solved, was missing just one line that fixed it all.
WiFlyClient client;
