I got wifi working on RPi4B 4GB, and RPi Zero W with Buster, with only the following. Using a couple months older version of:
https://wiki.debian.org/WiFi/HowToUse
It was Command line section, now is Using_ifupdown section:
To get interface name (wlan0):
# ip a
To bring up interface:
# ip link set wlan0 up
To scan for networks (not necessary at home):
# iwlist scan
Edit /etc/network/interfaces.d/wlan0
Uncomment lines and change to my wifi SSID and password.
To connect (have some patience):
# ifup wlan0
To verify IP address:
# ip a
It's probably better, more secure, to use WPA-PSK so the password is encrypted, but the above was simpler and worked.
