Arduino IDE 1.0.5 Mac OSX and Arduno WiFi Shield

[alejo-reyes]

I upgraded to Arduino IDE v. 1.0.5 Mac OSX recently and I just realized after hours and hours of frustration that there seems to be a bug when compiling sketches involving the Arduino WiFi library.
I'm used to use my mac book air when I have to work at field with my arduino installation since it is very small and lightweight. Well, I started to notice wrong behavior with my WiFi connection after compiling a sketch that worked fine when compiled in my previous version of Arduino IDE in Mac OSX. But it was just yesterday, after hours and hours of trial and errors that I returned to the office and compiled the very same sketch in my PC version of Arduino IDE (v.1.0.3) and it came back to work like a charm.

I decided to downgrade to Arduino IDE v.1.0.4 in Mac OSX and the sketch compiled well again. I must confess that I didn't try upgrading my PC version of Arduino IDE to 1.0.5 for testing this wrong behavior but fortunately I didn't because if it would have had the same bug in the PC version, it would have taken a lot of time to discover this bug.

This is the configuration I was working with when detected the bug:

• Mac Book Air 11 inch
• Mac OSX 10.7.5
• Arduino IDE v.1.0.5
• Arduino UNO R3
• Arduino WiFi Shield

The wrong behavior in my sketch was that even though the WiFi Shield was able to connect to the WiFi router, after that, there wasn't any connection as client or server to servers or clients in the local network or the Internet.

I hope my report will be useful for others and the bug will be revised and solved very soon. It would be nice to have better documentation also.

Which chips do you have on your Wifi Shield...
I have one with an Atmel AT32UC3A1512 and HDG204.

I can confirm that I just went through the same screaming frustration on PC. The example found here -

http://arduino.cc/en/Tutorial/WiFiWebServer

Would not work using 1.0.5 of the arduino software/driver on PC. Downgrading to 1.0.3 in my case for both driver and software allowed the code to work as expected.

The behavior was that the shield in the example sketch above would happily connect to wifi, get an IP, and was even pingable. However, any and all client connections would fail. Telnet attempts would close instantly and the serial console would not see the client connection attempt.

Hi,

I got a WiFi shield today and after several hours of frustration, I can confirm I have the same issue as reported by alejoreyes when using the IDE 1.0.5 on Mac. The WiFi Shield doesn't work properly, specifically the problem I had was with the client.connect command where client is of type WiFiClient.

After searching the internet I found a reference to using IDE 1.0.3. Fortunately I have a PC with Win7 where I was able to install the IDE 1.0.3 without changing my IDE 1.0.5 on Mac that is working fine for everything else I'm doing with my Arduino.

With this environment, the basic test sketch that was not working in Mac with IDE 1.0.5 worked perfectly with IDE 1.0.3. Not sure if this is also related to Mac vs PC, but at least it seems to me it is a IDE 1.0.3 vs. IDE 1.0.5.

Hopefully this issue is address and the IDE 1.0.5 on Mac works as expected when using the WiFi shield.

I have the same issue, the wifi shield can't connect to a client, I can ping it fine, but I can't connect to it.

Im using:
-IDE 1.0.5 OSX
-Arduino UNO
-WIFI HDG204 (Firmware 1.0.0)

I can confirm it works properly when reverting to IDE 1.0.3

Try using Arduino IDE 1.0.4 or earlier.

Same here: moving to 1.0.2 solved the issue. This should really be fixed, BTW!

maybe you have an old firmware on your shield. Try to update it. It should solve the problem.
