My new pi0w isn't connecting to my home wifi in a headless environment. Here's my set up:
$ ifconfig wlan0

My /etc/wpa_supplicant/wpa_supplicant.conf looks like:
country=US
update_config=1
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
network={
ssid="xxxxxx"
proto=RSN
key_mgmt=WPA2-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk="xxxxxx"
}
and my /etc/network/interfaces looks like:
# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
auto lo
auto wlan0
iface lo inet loopback

It's finding my relevant network when I run sudo id dev wlan0 scan:

Any thoughts?
sudo iw dev wlan0 scan? Do you find your hotspot? – Ingo Apr 21 '18 at 19:38
