arduino yun openwrt software update failed - no wifi

Hello,

I can't see a wifi signal and can't start bridge after updating latest openwrt on my yun. How do I fix it?

I updated my arduino yun using the web panel procedure:

I did this buy downloading this file:

openwrt-ar71xx-generic-yun-squashfs-sysupgrade.bin

and copying it to a microsd card and inserting the card in the yun and following the above web panel procedure to upgrade. (Note: Out of the box, my wifi worked and broadcast a linino name and required doghunter password)

After upgrade, I can't see the wifi signal from the yun. I've restarted, repowered, reset everything I can think of including the 30s reset of the wifi button.

After I upload wifistatus from IDE->File->Examples->Bridge->Wifistatus, I only see "starting Bridge..." in the serial monitor, and none of the expected wifi info.

After uploading the yunserialterminal sketch to the yun, and watching the serial monitor while I hit the yun reset button on the board, I get the following info on the serial monitor. (see attached text file)

Please help. I'm not sure what to do next to fix this. Thanks.

@grarduino
if you are using an SD card for additional storage, it appears to be loose. Make sure it is plugged in all the way. It may have come loose when you were working.

I have exactly the same problem and did the same procedure. Also "(Note: Out of the box, my wifi worked and broadcast a linino name and required doghunter password)" I hope some can help. Thanks.

Me too

Try this way >> https://www.arduino.cc/en/Tutorial/YunUBootReflash

First upgrade 1.5.2 firmware, then use these steps as a guide. I was able to successfully upgrade and and fix Avahi so the Yun shows up in Arduino IDE (over WiFI) again.

If you run into any issues not covered in those posts, let me know and I'll update the guide.

I've had the same problem after updating the latest openwrt on my yun. It may be because I started with Linino and am trying to change to OpenWRT? I can now no longer connect to the Yun through USB and ethernet cable. Any suggestions? Thanks.
