I was using Wlan0 but in the middle I do not know where I messed up wlan0 wasn't starting automatically instead my pi3 was trying to connect through ethernet with LAN cable plugged in, so I unplugged LAN cable it was still not having wlan0 started automatically so I have put this below line in /etc/rc.local

sudo /etc/init.d/networking restart; sudo ifup wlan0

Is it ok to put in /etc/rc.local I am doubting because earlier it used to start automatically without this line in rc.local?

Contents of /etc/network/interfaces

# 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
iface lo inet loopback

iface eth0 inet manual

allow-hotplug wlan0
iface wlan0 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan1
iface wlan1 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

  • What's the content of /etc/network/interfaces ?

  • Without commenting on the strategy itself, don't use sudo in /etc/rc.local; it's run by init with privileges. If you wish to test it, then use sudo rc.local instead.
