i'm new at RPi. Today, i installed NOOBS and tried to turn on Wi-Fi. When i clicked network icon (next to the bluetooth icon), it written "no wireless interfaces found".

I typed to terminal "sudo ifconfig". There is no wlan0. I edited wpa_supplicant.conf, it didn't change anything. I tried to change wifi country code on raspi-config but "no wireless interface found","There was an error running option I4 Change Wi-Fi Country" errors showed up. So what should i do?

  • I asked the one that used this device before. He is not sure, he encountered with some errors about it

  • try a different image - raspbian (full or lite) - I know NOOBS is supposed to be "easy", but it seems it's easily broken

In a console with ip link show you should always see an interface for wifi, mostly wlan0, no matter if wifi works or not. if not, it is likely that you have a hardware problem. Look at After fresh Raspbian-Stretch install my WiFi isn’t working on my Raspberry Pi 3 anymore for further information. To narrow down the problem you my consider only for testing to install Raspbian Stretch Lite 2018-06-27. It does not need much resources and may reduce side effects in configuring wifi.
