wpa_supplicant

Wed Dec 02, 2020 1:30 am

Heloo,
I get RaspberryPi 0 W, and wanted to set it up as headless.
Installed Raspbian and added conf and wpa_supplicant with name and pass of my network ( changed premade file ).
I cannot connect my Rpi on WiFi, they dont show on dhcp server. There is message in log:
"B8:27:EB:A4:63:F4@wlan1: connected, signal strength -53" and 5 seconds later "B8:27:EB:A4:63:F4@wlan1: disconnected, unicast key exchange timeout"

wpa_supplicant file:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US

network={
ssid="Mikrotik_Mikrotik"
psk="PASSWORD"
key_mgmt=WPA-PSK
}
In Security Profiles next is checked for pass: WPA PSK, WPA2 PSK. Unicast and Group chiper booth is aes ccm.
Wifi analyser on android says Im using: WPA2-PSK-CCMP

Is my wpa supplicant config wrong?

Can you try without the key_mgmt option?

Thanks for the working configuration! I was tearing my hair out with this exact same problem. Both "raspberry pi can't connect to wifi" and "unicast key exchange timeout" are essentially ungooglable problems, especially since this seems to be specific to the Raspberry PI W 0.
