Hi,
I've gone through your project brief and understand the following:
[*] You have a Raspberry Pi 2 connected to a router.
[*] You have a Wi-Fi dongle connected to the USB port of the Raspberry Pi.
[*] You want the Wi-Fi dongle to broadcast a wireless network (SSID)
[*] Clients who connect to this network will be redirected to a splash page (An app that will be running off the Raspberry Pi that requires Facebook login for authentication).
Based on the project description, my role is to:
[*] Configure the Wi-Fi dongle to broadcast the SSID.
[*] Alter the Domain Name System (DNS) on the Raspberry Pi to redirect users to a splash page on the Raspberry Pi.
Please, let me know if I understand you clearly, if I don't, do come on chat.
