Can't connect to my router using the official Arduino WiFi shield.
I'm trying to get the example ScanNetwork to work using an Uno R3. The sketch compiles and runs but mostly (95% of the time) returns 0 networks found. Occaisionally it will find my network reporting the correct SSID (and reasonable signal strength) name and WPA2 encryption, but very rarely (1 in 20 attempts). I've tried various physical distances between the shield and the router and provided the Uno with extra power other than the USB. Whatever I try it nearly always reports 0 networks found.
I've tried using the example client for WPA2 but that always results in the red error light coming on staight away and the software reporting that it was not found.
I thought it might be the firmware, but I have not been able to upgrade even following the only windows instructions I've found on the webhttp://www.dfrobot.com/community/2012/11/how-to-upgrade-arduino-wifi-shield-firmware-on-windows/
This process fails when attempting to program using AVR32 studio giving an error ('batchisp' is not recognized as an internal or external command,operable program or batch file.)
I think I'm either missing something obvious, have rubbish firmware or have an intermitent duff peice of kit!? I dont usually post on forums as I usually find answers to my issues on existing ones, but there seems to be no one posting this. I'm somewhat frustrated and starting to think about getting a refund from oomlout with a view to using an Imp.
Please stop from travelling down that road :-) ....
The green wire on the back doesn't fill me with confidence either (what's that ?)
