I've loaded the new version with wireless_mode defined.  Still only getting the first request successfully.  Subsequent requests fail.  For what it's worth, here's what is being reported by the serial.print()s:

I will play some more with it tomorrow.  Woot, always fun being an early adopter.  smiley-grin

I know IP and MAC adresses normally hasn't anything to do with eachother, but at my home it has (also like estranged - he is also using the MAC filter)
I'm using the MAC adress to check if the computer is know, and then the computer gets the same IP adress everytime!

So... I would like to know, if the MAC in the WiShield is unique, so it can't be changed? As it isn't unique in the Arduino Ethernet Shield (Wiznet)

The MAC address is programmed unique from the factory of my Wi-Fi module supplier.  So MAC filtering should work fine, however, since the out of the box solution is only using static IP addresses, this is less of a concern since the address you supply in the sketch will be the address used.

As an exercise to the user later, the function zg_get_mac() should give you the info you need.  8-)

Ahh good smiley
Also, my next question would have been: "Then where can I find it's MAC?" - But you answered it, even before I've asked smiley-razz

Ok, new code drop (just stack code changes from my last message about new code).  The code can handle multiple GET requests without causing the lockup.  I was able to test it with both an unsecured and WPA2 secured network on Firefox.  Safari on my Mac still is giving me issues.
One of the fixes we put in is temporary until we understand TCP a bit more.  
Anyway, give it a shot.  It should be more stable now.  smiley  

Time for some shut eye now.

Awesome, got mine working.  I am able to ping it now and see the webpage with Firefox.  Great work!

The MAC is also printed on top of the actual wifi module.  Took me a while to find that too.

Confirmed that the new code allows for multiple requests / reloads on Firefox.  However 1 request from Safari works, then subsequent requests fail from anything.

Tested on a WPA Personal network.

Keep up the good work, and yes get some sleep. smiley

Safari might be a bit particular about the html served, try this in WebServer.pde

Code:
const prog_char webpage[] PROGMEM = {"HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n<body><center><h1>Hello World!! I am WiShield</h1>"};
const prog_char webpage1[] PROGMEM = {"<h2>This is line 2</h2></center></body>"};

<h1> in between a <p> tag isn't valid html. I don't have a shield yet to test it but its worth a try if you run out of other ideas = )

As I haven't recieved the module yet, I would like to ask if you can use the browser on an iPod Touch or iPhone (I have seen you have done it, Brad - but without the multiple request problem?)
It's because the iPod Touch and iPhone uses Safari as browser!

I'm missing something here, I've tried this and cant get it to compile, tried #include <g2100.h> and still it cant see it.  I'm sure I'm running into a "trying to remember C/C++" issue but I'm stuck.

Mobile Safari does not seem to have the problem that desktop Safari does.  I'm able to reload the page multiple times just fine on my iPhone.

So we took a wireless sniffer to the module when the Safari client comes in to access the arduino, and it seems that the client is doing something that it shouldn't be doing.  We're still debugging.

g2100.h is not a library header file and the Arduino IDE will not be able to find it. You can print out the MAC address on the terminal by inserting #include "g2100.h" in the WiShield.h file and inserting the following code in the while(1) loop in the WebServer sketch.

Code:
if (zg_get_conn_status()) {
      // read MAC address from device
      my_mac = zg_get_mac();
      Serial.print("MAC : ");
      for (i = 0; i < 6; i++) {
            Serial.print(my_mac[i], HEX);
      }
      Serial.println();
}

This shows how you can use the other functions defined in stack(stack.c) and driver(g2100.c) files. If you are just trying to find out the MAC address, it is also printed on the label on the WiFi module.

@BenQuark

Can you provide a snippet that shows where the #include "g2100.h" should be inserted in WiShield.h? I tried, but can't get Arduino IDE to compile.

I get a long list of errors related to WiShield.h

In file included from hardware\libraries\WiShield/WiShield.h:38,


hardware\libraries\WiShield/g2100.h:208: error: 'u8' does not name a type


hardware\libraries\WiShield/g2100.h:209: error: 'u8' does not name a type


hardware\libraries\WiShield/g2100.h:210: error: 'u8' does not name a type

etc...
