Looking at connui-wlan it looks like a wizard plugin can be used to add more settings automatically to Advanced settings:

22:30 < Wizzup> parazyd: freemangordon: looks like connui plugins can have plugin->advanced_show = to have settings show up in advanced settings, so we could do that
                for provider

Also see iap_wizard_dialog_activate_advanced_settings in connui-internet/src/settings/wizard.c

The "Other" tab in advanced settings comes from the connui-wlan plugin, which uses conn_set_iap_ti_adv_misc which is apparently Other.
