Unable to access the Arduino YUN wIfi

Official Hardware Classic Yún
1

Hi,

I am working on Arduino YUN these days. I am having a problem. In the start , it worked fine, I read tutorials and configured it with my Wifi connection using Arduino.local and everything went well. But yesterday when I tried to connect to Arduino YUN wifi in order to configure it. It gave the Limited Access :((

I tried again and again but no luck after that it simply dissappeared from my Wifi List, I uploaded the sketch blink using serial COM port and it uploaded and working fine but I am unable to find the Wifi connection and hence cant open Arduino.local

I have also searched on other laptops but Arduino Wifi is not coming in any laptop. I am afraid now. Is it burnt or something??? Do I need to buy new YUN or is it something about the settings and if it so How can I reset it back to factory default ???

I have also pushed the button for almost 1 minute but no luck.

Moreover the blue LED WLAN is blinking continuously. Sometimes it stops but again start blinking after some time.

Please let me know what to do ???

Thanks.

The wifi-live-or-reset is kick in. Disable wifi-live-or-reset might help.

http://forum.arduino.cc/index.php?topic=188101.msg1591819#msg1591819

follow the same thread to get wifi Signal level strong. Once it works then re-enable wifi-live-or-reset.

I have tried this method /usr/bin/reset-to-factory-anyway ..... but it doesnt give anything on serial ....... By ~2 I enter in the linus but when I give /usr/bin/reset-to-factory-anyway this thing it doesn't show anything .... What should I do ???

Thanks.

When I use YUN SerialTerminal example and hit the reset button , I get this response

Sir,

I really need your help, Can you talk to me on skype ..... May be we can solve it using team viewer .... you control my PC and let me solve this issue ...... Please I am really stucked ....... I have tried everything ..... This thing too run-sysupgrade openwrt-ar71xx-generic-linino-16M-squashfs-sysupgrade.bin .... but no response ..... I am even ready to pay .... Kindly let me know ..... thats my skype : theenggprojects

Hi,

Thanks a lot, I really dont know how to thank you .... I have finally reset my YUN and now its appearing in my Wifi ..... I opened the Arduino.local and it opened then I configure the Wifi network available.

But here I got into problem .... When I connect my YUN to wifi network, it got stuck there. Although it restarted but after that when I try to access it again , it doesn't load up. Neither it come in the Wifi Connections and when I run the WifiCheck Example , it shows that I am connected to new Wifi connection but there the speed RX / TX is very low i.e. 8KB . Here's the log:

Current WiFi configuration
SSID: XEO
Mode: Client
Signal: 80%
Encryption method: WPA PSK (NONE)
Interface name: wlan0
Active for: 18 minutes
IP address: 192.168.1.102/255.255.255.0
MAC address: 90:A2:DA:F2:01:73
RX/TX: 18/25 KBs

Kindly check it .... Why my YUN is now working slow ????

Thanks again Sir.

Thanks a lot bro for all the help you have done in order to help me out in my project. I will surely post a complete tutorial on Arduino YUN on my blog for others. I have completed everything but I am stuck on a small problem and hopefully the last one as everything else is now working. The problem is:

In order to upload the data to my ftp account I am using the below commands:

Process UploadW.runShellCommand("curl -T /mnt/sda1/datalog.txt" + Ftp_Server + Username_Password + " --append ");
     while(UploadW.running);

Its working fine but the problem is during Upload if I lost my Wifi Connection somewhere then my YUN got stuch in the while loop and doesn't come out of it. I have also tried the if but no luck. Kindly tell me how can I place a check in my code that if the Wifi is available then keep on uploading and if Wifi is not there then simply come out and do the other task, just don't stuck.

Thanks.

A lot of unstable Wifi connection is related with Wifi Signal Strength.
