Has there been any progress on this? All of my gadgeteer stuff has been collecting dust in the closet for a couple months now. Wondering if it’s time to start up again or put it up for sale.
@ scicco, I just tried this and it worked perfectly. If you have tried different routers and different Spider boards, what about a different WIFIRS21 module?
I used the exact code John posted here:
https://www.ghielectronics.com/community/forum/topic?id=16349&page=4#msg162965
Device:
Spider rev 1.0
WifiRS21 rev 1.2 (plugged into socket 9)
netmf 4.3
Gadgeteer SDK 4.3.6.0 (2014 R5)
Tiny Bootloader 4.3.4.0
Enviro:
Windows 8.1 x64
VS 2012 Express Update 4
Router:
Asus RT-N66U w/Asus firmware 3.0.0.4.376_1071
WPA2-PSK AES
I just ported all my projects from 4.2 to 4.3, including my RS21 wrapper util for easy networking, and I saw this thread. I got my stuff working, so I figured, what the heck, I’ll try Johns code too while I’m at it. It’s not often someone in the community will jump in and flat out help repro, but you’re welcome! Hope it helps!
@ dapug -
I have not tried any different boards, modules or access points. This is just a hobby I’m trying to get into and don’t want to spend any more money than I already have. All the software is downloaded on my desktop at home so I can’t try it anywhere else.
I did notice from your post that the Gadgeteer SDK has been updated since I last tried this. I’m going to blow the dust off everything and give it another shot over the holiday. Thanks -
Yeah, give it a whirl this weekend. Just don’t try and sell it right now - hard to beat GHI’s black friday sale on the spider. 
If you’re going to update everything, I recommend you update your tiny booter too. Follow the steps on section 5.2 of the EMX manual:

When it prompts you to flip dip switches on the spider, the picture can be confusing. Just turn on switches 1, 2, 3 for the procedure, then turn remember to turn off.
After this, of course, update the firmware with the same config tool (but sure to select 4.3 when doing that)
Lets hope your hardware is not physically the problem. It’s unlikely, but quite possible. You can read my recent tale of woe here:

Got everything updated and…it works!!! I still had a standalone project with GHI’s code and at first it did bark at me for the GHI.Pins and GHI.Networking references but worked after deleting and re-adding those.
Going through the release notes and saw this:
All Boards
Changes
- Improved networking reliability.
- Fixed sending large buffers in networking.
I had another unresolved issue with returning data (https://www.ghielectronics.com/community/forum/topic?id=14322) that I’m going to get back into and see if it is resolved as well.
Thanks!
