I have been google around about the issue. I have tried with different images: from 2017 to 2021, lite, desktop and full desktop. no success.
If you have raspiberry pi zero w v1.1. wifi does not working. There must be something with linux image. I am highly double there is issue with hardware.
The first command check whether wlan0 exist:
cmd: ifconfig -a
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1000 (Local Loopback)
RX packets 16 bytes 1922 (1.8 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 16 bytes 1922 (1.8 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
read your dmesg
cmd: dmesg

I am quite disappoint with this board. I liked raspberry pi because of their reputaton about well support software. apparently, this is not true.
The only way to get software raspiberry pi w is via USB + Pc.
