Use routers to set up the local network in your location, connect equipment, make synchronization of receipts between register and management console or set up the separate Wi-Fi network for your guests.
We tested and recommend Keenetic Extra KN-1711, Asus RT-AC52U B1 and Linksys EA6100 routers.

Pay attention to routers characteristics before buying it:

USB 2.0 for for modems with 3G / 4G support. For example, if there is no internet connection in your location or it’s impossible to connect it with the provider cable.
