I need your help.
I downloaded arduino IDE 1.0.5 and I upgraded my WiFi shield with the included firmware because I hoped to get better performance and support to UPD.
Unfortunately after the upgrade my shield was not recognized anymore (Shield not present) and/or it was not able to connect to my wifi network.
I decided to get back to a previous firmware (that is included into the IDE 1.0.3).
Now the shield is recognized (almost anytime) but:
1) scanning the network it hardly shows my network (router is few inches far from the shield) and it doesn't show other networks
2) even though it can connect to my wifi network, it doesn't connect to any site and it doesn't accept any connection. I have tested some samples (WiFiWebClient, WiFiWebClientRepeating, SimpleWebServerWiFi) and they don't work
Same results with the firmware included in IDE 1.0.4 and firmware from here https://github.com/arduino/Arduino/tree/master/hardware/arduino/firmwares
Since I am working on a Mac, I have tried to upgrade the firmware on Windows too, same results.
Can anyone give me any advice ?
Is there any place where I can download the original firmware which was slow and unreliable but at least I was able to connect to the shield ?
