There is no separate option for enabling/disabling network connection icons in the login dialog and/or on the locked screen. With Show taskbar in login screen and Show taskbar in screenlock enabled, they appear automatically if the option Enable tray icon is activated under Setup > Network > LAN Interfaces > Interface 1 (or Interface 2, Wireless) and/or under Setup > Network > Mobile Broadband (and/or VPN).
The network connection icons in the login dialog and on the locked screen, with the exception of the Wi-Fi icon, serve for information purposes only and thus are inactive on clicking.
The Wi-Fi icon invokes a dialog for turning Wi-Fi on/off or the Wireless Manager in case it is activated under Setup > Network > LAN Interfaces > Wireless.
