I'm following these instructions to create an Ad-Hoc WiFi network from a Pi Zero W. It works great. Problem is, once I'm done I want to switch the Pi back to DHCP and log on to my house WiFi like normal.
1) Replace the old files:
/etc/network/interfaces to their original states from a backup before the Ad-Hoc instructions were followed
2) I'm trying to restart networking with:
sudo ifdown wlan0 sudo ifup wlan0
... and I've tried all these commands as well following that:
sudo service networking restart sudo /etc/init.d/networking restart sudo systemctl daemon-reload
No matter what I try, I can't get the Pi to give up it's static IP and connect normally back to my home WiFi... UNTIL I restart the computer. How else can I force the network to reload
/etc/network/interfaces without powering cycling?
Here's the interfaces file BEFORE adhoc, which is restored AFTER adhoc:
# 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 wlan0 auto lo usb0 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 allow-hotplug usb0 iface usb0 inet manual
during adhoc the wlan0 part is changed to:
allow-hotplug wlan0 iface wlan0 inet static address 192.168.0.1 netmask 255.255.255.0 network 192.168.0.0
...and that's the problem, I can't "clear" that static IP address so the Pi won't connect to my router.
