Hello from a few days I approached the ARDUINO world I m ignorance on the this subject.
In the afternoon I run this https://www.arduino.cc/en/Guide/ArduinoYun#toc6 guide
Once executed it seemed that everything went the right way.
A little later I noticed that the WiFi was wrong anymore, also trying to press the WLAN button I did not get results.
Then I tried to compile the sketch "WifiStatus" but nothing opening the Serial Monitor is stuck on 'Start Bridge ... "
When i run a "YunSerialTerminal" sketch i get this result:
[0.200000] bridge: automatic filtering via arp/ip/ip6tables has been depreca ted. Update your scripts to load br_netfilter if you need this.

The Linux side of the Yun is not booing properly. I'll leave it to someone with more Linux experience to help you with that.
But, with the Linux system not running, the rest of what you describe is normal: any sketch that uses the Bridge Library will indeed get stuck at the starting bridge step, as it requires cooperation with the Linux system which is not running.
Also, any of the reset operations mentioned in the link you provided will not work at this point. It doesn't say so in that documentation, but anything to do with the WLAN RST button won't happen until Linux is fully booted. This is unfortunate since most system reset buttons like this work immediately after power on (or you hold the button while applying power.) But not here - you must wait until Linux has fully booted, usually at least a minute, before you start the button press. However, since your Linux system is not booting, you are beyond the point if recovering with a WLAN RST button press.
Another newbie here, I've fallen into the same trap, tried to follow the instructions in the guide linked above but am failing at the point where I ping my pc. The TFTP server is running.
My PC and Yun are both connected to my router via Ethernet cables. My router doesn't seem to see the Yun though, I can't see it on the network, I assume this is where I am going wrong, but like I said I am a newb so not sure what to do next?
This is where i'm having trouble as well. Is there a fix for this? I have tried the above and no luck. i noticed this is an older thread and wonder if there is a new fix?
Or idea to get me back on track?
Nothing above helped me either. The only way I got it working again was following every step in this guide:
It says it voids your warranty, but following the official upgrade instructions (https://www.arduino.cc/en/Tutorial/YunSysupgrade) is how I got here in the first place, so I'm not really sure what else to do.
