Gus I know where your going with this and I’m rather excited about it as its going to be incredible when its done, but for now it takes a bit of stick handling to get things to work, but I got mine to work.
@ Duke: Did you update the WiFi firmware manually when you said your running version v1.2? IF so, how did you do it? Also, were you able to pull an ipaddress once you connected using DHCP?
It did check my wifi firmware but it didn’t need to be updated: RS9110 driver version Number is 4.4.5 (it was updated in the past, but that might have been during the 4.1 days)
What version of the wifi module are you using?
DHCP is how I connect to this wifi so its working here.
This what I see in the output window when I start this app
deploy and loading stuff here

Network Address Change
etc etc etc
So i have the same firmware version as you. The reason I asked about your IP address is I can’t retrieve the IPaddress using DHCP although everything works (NTPworks fine). The IP address always defaults to all 0’s.
Dear Duke Nukem;
When I test your code, I got some errors

A first chance exception of type ‘GHI.Premium.Net.NetworkInterfaceExtensionException’ occurred in GHI.Premium.Net.dll
Exception was thrown: GHI.Premium.Net.NetworkInterfaceExtensionException

@ Tzu Hsuan: No, I didn’t. I’m still waiting for a reply from Gus, but it seems like nothing is moving forward. I really hope this is resolved soon or at least someone comes up with a bypass. I’m lost for now
I also have the problem with EMX/Cobra, BuiltinEthernet, FW 4.2.7.0 and DHCP.
Sometimes I get an IP address, sometimes you wait ages and nothing happens.
As soon as I use a fixed IP address, I have no problem anymore.
Glad my code (that I no doubt got most of it from folks here) helped. Given some of the changes which have occurred lately I really should redo it to include some of the built in Time features etc.
Again a big props cause is the only version of code with the actual WiFi NETMF.
For me, I was doing the same thing then you on my side, and I reach the same point of your code. But I got a problem, I dont know if you had it too, but all my connection is open I had an IP address etc., but when I do WebClient.GetFromWeb("…") … it always trigger me the response receive event, but with no response text and a status 302 instead of 200… so I test your code to see if was me the problem or a “I dont know what problem”… and with your code I had the same result … I really dont know where to search now … cause in your output debug that you put in exemple you had a response.Text …
So if you can help me in any manner you see, I will appreciate it!
Cheers!
Two other things. Welcome to the forum. Please, in future, don’t double post. People will see your posts and reply if they can help if you just do it once.
