@ KG1 -
I am aware of the issue as I had similar with my Spider. I forgot to say that in my first post.
I would assume that GHI is fully aware of this but I thought I should post anything that I saw that was ‘consistent’ each time I tried it.
I’ll look at your code in codeshare.
Thanks again…
@ andre.m - Dangerous to make assumptions now 
Just a thought … if you receive a valid IP after each power up, but not after a reset… you might consider to pragmatically reset the internet device…
@ andre.m - It works much better as before, but i am still testing on G120 and WiFi cos no consistent results… Sometimes hard to Join Router… Sometimes no IP from DHCP… Sometimes socket exceptions… Using Cisco EPC3925. Continue testing today…
It seems that calling _wifi.NetworkInterface.EnableDhcp() in a loop works as a work-around for me…
Log.Instance.WriteString(LogMessageType.Info, "GetDynamic IP");
int retryCounter;
for (retryCounter = 0; retryCounter < 10; retryCounter++)
{
try
{
DebugHelper.DebugPrint("Get IP through DHCP..");
if (!_wifi.NetworkInterface.IsDhcpEnabled)
_wifi.NetworkInterface.EnableDhcp();
else
_wifi.NetworkInterface.RenewDhcpLease();
int counter = 20; // wait 20x500mSec = 10 seconds max
while (!_ipAddressSetResetEvent.WaitOne(500, false))
{
DebugHelper.DebugPrint("IP address is not set yet.");
if (--counter == 0)
{
break;
}
}
if (counter > 0)
{
DebugHelper.DebugPrint("IP address is set");
return;
}
}
catch (Exception e)
{
Log.Instance.WriteException(e);
StatusLed.Off();
Thread.Sleep(100);

@ Tzu Hsuan: It’s good to see you modifying my code for Gadgeteer libraries. I have had no experience with Gadgeteer so cannot help you with this. Also I have not previously seen such timing errors in the debug messages. Are you using Version 4.2.9.0?
The ProgramStarted method is not meant to take forever; the Gadgeteer core is warning you that it’s taking longer than expected. @ Tzu, you can either use the code originally posted here by GHI (in a console app) or do as the Gadgeteer core suggests and move the initialisation outside programstarted() method.
I use the GHI NETMF v4.2 and .NET Gadgeteer Package 2013-02-14 Testing.
I try simple testing but still get 0.0.0.0 IP adress and can’t connect to internet.

Update:
I posted about receiving three wifi_NetworkAddressChanged events.
I have found out that > I < was causing the multiple interrupts.
It appears the my use of ‘display.SimpleGraphics.DisplayText()’ is causing some timing issue.
I do receive the proper IP from DHCP even while using SimpleGraphics.DisplayText() but it does cause the issue.
Using Debug.Print() does not cause the multiple interrupts.
Using a Cobra II.
@ Tzu, please use ghi’s code. They’ve explicitly asked for you to use their known working code, and to provide additional info about your network setup.
@ Brett -
Geee it was for @ Tzu
Oh well… The comments below still apply because using the display did give me a problem.
I did EXACTALY that originally. I gave the results I found using ‘their known working code’ without ANY changes.
I stated that received a valid IP from my router using my Cobra II.
I believe I posted what I did when I tried printing to the LCD. Maybe I forgot to say ‘why’ I did.
I was trying to track down a issue I had getting DHCP with my Spider some time ago using 4.1 and 4.2.
I was receiving multiple NetworkAddressChanged events on the Spider and Cobra II
and I wanted to find out if I could duplicate the problem. (At least with my boards and router)
My post was only to inform others that using the display ‘did in fact’ cause a repeatable problem
that caused multiple NetworkAddressChanged events.
I did not intend to cause confusion.
Have a GREAT day!
I’m not trying to have a go at @ Tzu, just point out that using code that GHI haven’t confirmed “works” for diagnosing the DHCP problem, when they’ve explicitly asked to use that code (making minimal changes if needed), doesn’t add value to this thread. It’s fine to have that conversation elsewhere, but the key goal here was to drive out a pretty serious problem by capturing the same information from as many people who have the issue using a repeatable process, so the value of that information gets maximised. We’re unfortunately adding to the noise to signal ratio here…
Using MFdeploy reboot CLR via menu, Board remain power
For those who are curious what the Dutch phrase of the SSID means… “I am so Happy” But i guess i am going to change this phrase

I have extended the two test from above to show that EVEN a valid IP address is assigned… Does not always guaranty that sockets works well…
I have tested this with GetDnsHostEntry as wel as trying to connect and send data to a local device over sockets
for (int i = 0; i < scanResult.Length; i++)
{
if (scanResult[i].SSID == "MatRouter")
{
wifi.Join(scanResult[i], "Wi$1024Fi");

Debug.Print(iph.AddressList[i].ToString());
}
}
catch (Exception e)
{

Thread.Sleep(-1);
Repeated the test with a Chinese brand portable router, one that is close to my desk and no other devices connected too…
Same kind of behaviour as my Cisco… One time it works, the other time it wont… 
@ GHI - Have you checked the latest firmware (4.7 2/1/2013 ) from RedPine. I just noticed that there is a more recent version, but don’t know if there are changes that might be interesting to us…
@ Brett -
I’m not trying to have a go at @ Tzu
I understand that…
At first, I thought it was for me! I’m OK with that also…
Can’t say I ever read anything unfriendly in this form…
@ willgeorge: Any testing that makes v4.2.9.0 a better product is worth doing. Keep up the good work. What you are doing is relevant to establishing a wireless network connection. It is interesting how often the class NetworkInterface appears to be associated with the variablity of outcomes. This class is in the centre of setting up a wireless network with its DHCP functions. Note that it is not in a GHI Library but in a NETMF Library. Perhaps under the hood there is multithreading causing timing differences (processor taking different time slices). I consider placing Thread.Sleep functions in the code is a relevant step in testing. It confirms whether the code can take some variability in the same way that your display adds variability.
OK, I modified GHI’s Code to Gadgeteer project.
change wifi to wifi_RS21.Interface
and comment it //Thread.Sleep(-1);
Spider mainboard
Interface: WiFi RS21 Gadgeteer module
I don;t really know the network setup in my company
ZyXEL Router in office don’t know the number.
DCHP Address obtained first try and can’t get the DCHP Address every time after a soft or hard reboot.
If I re-power the Router I can obtain DCHP Address only in the first time and Interface_NetworkAddressChanged event only raise in the first try also.

@ KG1 -
I have not had much time… babysitting Grandchildren…
However I had time to take the sample code that was giving me a DHCP IP address for the WiFi device on the first shot.
I was reciving only one NetworkAddressChanged and a proper IP address.
I added some simple code to see if I could get the default web page.
I have the correct IP address for the WiFi device.
//string url = "http://192.168.2.5:80/cobrawifi/";
string url = "http://" + WiFideviceIP + ":" + port.ToString() + "/cobrawifi/";
//Debug.Print(url);
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url) as HttpWebRequest;
string[] sResponse;
sResponse = new string[5];
sResponse[0] = "CONNECT";
sResponse[1] = "POST";
sResponse[2] = "GET";
sResponse[3] = "PUT";
request.UserAgent = "cobrawifi";
request.KeepAlive = false;
request.Timeout = 2000;
After adding the code I am now back to reciving three NetworkAddressChanged events.
Event 1 - I reveive the proper IP
Event 2 - IP 0.0.0.0
Event 3 - I reveive the proper IP
However I now have the visual studio Output window full of ERRORS…
Too many to post here.
I removed my T35 LCD from the board just to remove any possibility it has any influence on timing or something like that.
I checked my router and it shows that it is assigning a DHCP IP address that is correct
(My WiFi module has always came back with 192.168.2.5)
See attached image… Usually there are many more items in the DHCP list but most of the electronic ‘toys’ are off…
