I was curious so I checked my /etc/network/interfaces file. It would appear I don’t have the edit we’re talking about, yet my wifi never drops. Here is the file:
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 dhcp
auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wireless-essid XE1S3
