Rasbian Stretch - WiFi problem
After a fresh install I get this error when I try to connect to wireless:
Connection Error exit status 255 Successfully initialized wpa_supplicant
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ctrl_iface exists and seems to be in use - cannot override it
Delete '/var/run/wpa_supplicant/wlan0' manually if it is not used anymore
Failed to initialize control interface '/var/run/wpa_supplicant'.
You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.

Re: Rasbian Stretch - WiFi problem
Try to connect wlan manually, it is very difficult to troubleshoot this issue directly from nanodlp.

Got same issue , just delete the nanodlp wifi and dhcp setting files on /boot (or just rename it ) . it should then connect normally ...
