Yes, the only limit is that the router must have an ethernet port to connect Rialto WhiteBox gateway with the LAN Ethernet RJ45 cable included.

You can avoid the problem of the lack of ethernet port on your 3G Wi-Fi router by purchasing a “Wi-Fi to Ethernet” adapter, taking Wi-Fi signal from your router to provide an Ethernet port, and then to connect it to the Rialto WhiteBox control unit.
