Uno R3 with wifi shield. Upgraded firmware for 1.0.5, now it doesn't recognize the wifi shield (WiFi.status is constantly 255). While it is plugged in, the 'link' light is on for a few seconds, and after about 5 seconds the blue 'data' light goes on instead, and it stays that way.
Jumper is not on, firmware (both wifi_dnld.elf and wifiHex.elf) was updated using batchisp with no errors. Tried with a due and the Uno R3, both had same error.
Before updating the firmware, it would at least be able to recognize the shield and connect to a network, but I was not able to use two arduinos to communicate with each other as server and client, to send simple string messages. I decided to update to 1.0.5 to be sure it worked, and because I needed the config() function
