[    3.127628] r8169 0000:01:00.0 enp1s0: renamed from eth0
[    5.302161] r8188eu 1-1:1.0 wlx10feed2673c7: renamed from wlan0

wf=wlx10feed2673c7

root@x# cat /etc/wpa_supplicant/wpa_supplicant.conf
country=au
update_config=1
ctrl_interface=/var/run/wpa_supplicant
network={
        ssid="hi-fi"
        psk=#########
}

connected using cmd

root@x# wpa_supplicant -B -D wext -c /etc/wpa_supplicant/wpa_supplicant.conf -i $wf
root@x# cat /etc/network/interfaces
This file describes the network interfaces available on your system
and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
The loopback network interface
auto lo
iface lo inet loopback
iface eth0 inet dhcp
auto wlx10feed2673c7
allow-hotplug wlx10feed2673c7
iface wlx10feed2673c7 inet dhcp

is my /etc/network/interfaces is correct what is standard process of connecting wifi and "auto connect in future" (eg, reboot or wifi out of reange, then again in range) ???

or I have to use as it is?

auto wlan0
    allow-hotplug wlan0
    iface wlan0 inet dhcp

wifi connected ok, but i want auto connect , on boot, on signal in range
