Can detect but not connect to wifi network Kali Raspberry Pi

Question

So I've started going through some penetration testing books and tried to set up Kali on the raspberry pi 3b. I'm having some trouble, though, namely that Kali could detect all the WiFi networks around me right after I put the imaged sd card in the Pi, but cannot connect to my network, no matter if try via the GUI or via command line ( I followed these instructions for the command line, with wpa_supplicant etc).

The password is definitely correct, I quadruple-checked.

I also tried using an external USB-Wifi-Adapter, but without success.

(I might try checking if I can connect to the WiFi if I put Raspbian on the Pi next)

Now, am I correct in assuming that since it detects the networks, this can't really be a driver issue? I also used Offensive Security's image specifically designed for the Pi from here . Can anyone help?

Solution

Had the same issue, just open the terminal and type:

ifconfig wlan0 up

Change the "wlan0" with the interface you want to use. Type ifconfig to see all interfaces.
