[General]
EnableNetworkConfiguration=true


### optional:
[Network]
EnableIPv6=false

[Scan]

iwctl

• Auto reconnect on boot by default (auto select ssid with optimun signal)
• $SSID must be populated by scan in get-networks to connect/reconnect
• iwctl also starts iwd.service

iwctl device list

# scan (run once)
iwctl station $DEVICE scan [$HIDDEN_SSID]

# available ssid list
iwctl station $DEVICE get-networks

# (optional) pre-configure before connect with static ip

# #1 - to be saved as /var/lib/iwd/$SSID.psk

# disconnect - no auto reconnect on boot
