To create a Wi-Fi hotspot using a Shuttle modem, connect the Shuttle modem to a PC and access the admin page by entering the IP address in a browser. Disconnect the host-less Shuttle modem and connect it to a router, then turn on the router and Shuttle Wi-Fi. Connect devices to the SSID and enter the password. Access the admin panel again to change the SSID and password as desired and check the connectivity with the Shuttle modem.
