Hi;

I’m trying to setup my Jetson nano headless mode. During configuration I provide to WiFi’s WPA/PSK key but WiFi not configuring.
It give me " Failure of key exchange and association"
I’m double check every thing but I recive this error again and again.!

Jetson_nano_2gb_setup_error|661x419

If I pass this step, after the finishing setup I can’t edit /etc/wpa_supplicant.conf file because of permission restrictions. When I try to change this file permission using chmod It’s need root password. Configurator not ask me set the root password.

how can I fix this problem?

I was double check my router’s security settings (mac filter, mac authen etc.) everything is ok but still not connect.

My WPA2/PSK password is 26 char long is the be problem? Should I try another Wifi dongle ?

I solved this problem. I’m sharing the solution in case someone encounter the same problem.

N='SSID'       #Your Wi-fi's SSID 
P='WPA/PSKPassword'   #Your Wi-fi's WPA/PSK Password 
D=$(LENG=C nmcli -t d | awk -F: '/wifi/{print $1}' | head -1)
(nmcli -f NAME -t c | grep -q "^$N") && nmcli con del "$N"

sudo systemctl restart NetworkManager

sudo nmcli con add con-name "$N" ifname "$D" type wifi autoconnect yes ssid "$N"

sudo nmcli con modify "$N" wifi-sec.key-mgmt wpa-psk
sudo nmcli con modify "$N" wifi-sec.psk "$P"
sudo nmcli connection up "$N"

connection check

nmcli d
