I have bought one router with OpenWrt system.
Question : I want this router to broadcast two SSID at same time (one PPPOE and second Hotspot "authentication portal from Mikrotik router " ). so could you please support me in this using Luci GUI.
You write: 'router with OpenWrt system'.
Which router, which version of OpenWrt?
I doubt this can be done only within Luci GUI.
You must change some (wlan/network) settings on CLI, I guess.
But your idea should be possible, if your 'OpenWrt router' does support multi SSID channels.
