The Mac ID cloning is used After log in with phone or laptop.
Warning, not really for the faint of heart, but I think that’s what it’s purpose was ?
MAC settings
This section is only available if Advanced mode is enabled.
You can change/clone the Wi-Fi MAC address of the openSPOT. This is useful if you try to use a Wi-Fi network which uses a captive portal for authentication (example: hotel or airport networks). In this case, do the following steps:
Connect to the Wi-Fi network with your phone/tablet/computer, log in on the captive portal to enable the internet access for your phone/tablet/computer's MAC address.
Switch the openSPOT to access point (AP) mode by holding the button for 3 seconds.
Connect your phone/tablet/computer to the openSPOT AP, but exit the Initialization setup and open the Network page.
Set the captive portal Wi-Fi network's SSID and key at the Wireless settings section.
Click on the Clone button at the MAC settings section (make sure Advanced mode is enabled so the MAC settings section is visible).
