I got problem to connect my PXFMini on top of RBPi3 via WiFi. Two weeks ago there were no problems with connection but now (perhaps after some update) I cannot connect to it via WiFi. Linux is erle-brain-3-frambuesa.
What's more puzzling is when I plug ethernet wire to RBPi3 connection immediatelly revive - not only via eth, but via WiFi aswell. Its like ethernet cable wakes up frozen WiFi.
When rebooting with no ethernet cable plugged, WiFi rises OK, since I can see on DHCP it gets IP address, for few seconds repeats also ping, but suddenly went down and can't even ping on it, nor connect with ssh. But after I plug ethernet cable, WiFi comes back to life and stays alive even when unplug eth cable from it.
Here are my config file, if anything else needed I'll provide it:
