network={
ssid="your_hidden_ssid"
scan_ssid=1
psk="your_password"
key_mgmt=WPA-PSK
}
Replace “your_hidden_ssid” with the SSID of the hidden network and “your_password” with the network’s password.
Step 2: Bring Up the Interface
After configuring wpa_supplicant, you need to bring up your wireless interface and connect to the network. The exact commands may vary depending on your wireless interface name (commonly wlan0).
bash
sudo ip link set wlan0 up
sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
sudo dhclient wlan0
These commands bring up the wireless interface, start wpa_supplicant with the specified configuration, and obtain an IP address using DHCP.
