RPi Zero W no WiFi

I really don’t wanna give up on my Pi Zero W even though it is just $5. So here is my second attempt.

I did a recent install of DietPi on my Zero W with Ethernet hooked up with a USB adapter. Everything updated, however I can’t get WiFi to work. When I try to turn on WiFi module, I get a very short black screen with “n180211” on top left corner. It show WiFi is turned on in the “Network Options: Adapters” menu, however it is disconnected, this is how it looks-- Not Found- On - Disconnected. Sometimes if I try to edit the WiFi settings, it says something like, “Wifi hardware not found”.

I would really appreciate it if someone could share a solution to this issue. Thanks.
