Using an unencrypted Wi-Fi network or falling for a rogue access point puts your users' data at risk. Enable strong encryption and restrict Wi-Fi access to a default network and optionally employ a whitelist of additional networks in order to prevent this.
By default, Wi-Fi is not activated on IGEL OS. To activate it and preconfigure one or more allowed networks, follow these instructions:
In IGEL Setup go to Network > LAN Interface > Wireless.
Check Activate Wireless Interface.
Do not check Enable wireless manager, as this would give the user free choice of Wi-Fi networks.
Go to Network > LAN Interface > Wireless > Default Wi-Fi network.
