cannot read contents of wpa_supplicant.conf - Raspberry Pi Forums

i have set interfaces file , wpa_supplicant.conf files shown in tutorials can't connect. when ifdown , ifup error see is:

code: select all

wpa_supplicant: cannot read contents of /etc/wpa_supplicant/wpa_supplicant.conf run-parts: /etc/network/if-pre-up.d/wpasupplicant exited return code 1

thought meant made error somewhere, maybe space 1 shouldn't be, starting clean wpa_supplicant.conf , adding network info wpa_passphrase blah bluh >> /etc/wpa_supplicant.conf not work. i'm tearing hair out here!

this example of file wpa_supplicant.conf:

code: select all

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf 

code: select all

ctrl_interface=dir=/var/run/wpa_supplicant group=netdev update_config=1 country=gb  network={    ssid="wifi"    psk="passphrasehere"    priority=100 }  

take owner of file , permissions too:

code: select all

pi@rpi:~ $ sudo ls -l /etc/wpa_supplicant/wpa_supplicant.conf -rw------- 1 root root 241 oct 22 18:59 /etc/wpa_supplicant/wpa_supplicant.conf pi@rpi:~ $
