Create wifi hotspot (Deb 11 - Bullseye)
# Step 1: Add a new Wi-Fi connection with a specified SSID and configure it as a hotspot
nmcli con add type wifi ifname wlan0 con-name Hostspot autoconnect yes ssid BIGSSID
# - type wifi: Specifies that this is a Wi-Fi connection.
# - ifname wlan0: Indicates the wireless interface to use (e.g., wlan0).
# - con-name Hostspot: Assigns a name to the connection for easier management.
# - autoconnect yes: Ensures the connection starts automatically when possible.
# - ssid SI-T2b: Sets the name of the Wi-Fi network (SSID) to "SI-T2b".
# Step 2: Configure the Wi-Fi mode to Access Point (AP) and enable internet sharing
nmcli con modify Hostspot 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared
# - 802-11-wireless.mode ap: Configures the device to operate as an access point (hotspot).
# - 802-11-wireless.band bg: Sets the wireless band to 2.4 GHz (b/g standard).
# - ipv4.method shared: Shares the internet connection with devices connected to the hotspot.
# Step 3: Set the Wi-Fi security to WPA-PSK (Wi-Fi Protected Access with Pre-Shared Key)
nmcli con modify Hostspot wifi-sec.key-mgmt wpa-psk
# - wifi-sec.key-mgmt wpa-psk: Configures the network to use WPA-PSK for authentication.
# Step 4: Set the Wi-Fi password
nmcli con modify Hostspot wifi-sec.psk "mypassword"
# - wifi-sec.psk "veryveryhardpassword1234": Defines the password for connecting to the hotspot.
# Step 5: Activate (bring up) the hotspot
nmcli con up Hostspot
# - This command starts the hotspot using the defined configuration.
