I had my RPiZW working for a long time, lets say 400+ days with no issues so far.
Now for a unknown reason it didnt connect to my wifi network.
Connnected it to my TV, and started it. Its showing WLAN0 down.
If i go to raspi-config and configure the wifi again, it connects to my network but if i reboot it, it no longer connects. If i go again to raspi-config and setup wireless it connects again but some times it does not.
The piaware-config.txt file is correctly setup and my wireless key and ssid is also correct, my wifi network has other clients connected withou any issues.
It seems that the wifi is not beeing set as UP on boot.
Thanks in advance.
