Hello guys. I'm trying to get started with arduino Yun. According to the tutorials, the Yun should create a wifi network where I would've to connect. It doesn't appera. beginner's guide recommends to press the WLAN RST for 5 seconds but less than 30 seconds... Nothing happens. Try pressing WLAN RST for more than 1 minute, nothing happens. The guide says that when you press WLAN RST, the WLAN led should turn on. But it never turns on. Any help please? Thank you very much.
The arduino official page says
NB : In some countries, it is prohibited to sell WiFi enabled devices without government approval. While waiting for proper certification, some local distributors are disabling WiFi functionality. Check with your dealer before purchasing a Yún if you believe you may live in such a country. If you wish to disable WiFi, run this sketch. For more information, refer to this forum post.

http://forum.arduino.cc/index.php?topic=189105.0
In the forum it says how to disable de wifi, any ideas on how to enable it using the code in the forum?
Are you waiting long enough for the Linux side of the Yun to boot? It takes at least a minute for Linux to boot up and for the WiFi network to start up. One of the last boot actions is to turn on the white USB LED - be sure to wait for that to happen. In addition, any presses of the WLAN RST button are not recognized until Linux is fully booted up. Finally, if you successfully accomplish a WLAN RST button press, it can take many minutes of processing and rebooting before the operation is complete. Patience is necessary. It seems that the documentation never mentions how long some of these operations can take.
Have you tried a wired Ethernet connection? Can you access the configuration web pages through Ethernet? (After waiting for it to boot up, of course.)
Try connecting the USB port to your computer, and load the YunSerialTerminal example sketch. Connect to the Yun with the Serial Monitor, then press the YUN RST button. You will see a long stream of Linux boot messages. There may be long gaps when nothing is output. Wait several minutes for all of the Linux messages to be output, until Linux is fully booted and nothing has been printed for about a minute. Then copy all of the output and paste it here - that will let us see if anything is going wrong while Linux boots.
Hi,
I have a similar problem.
Thank you very much.
