The ASUS RT-AX57 Go Travel Router solves the problem of digital nomads finding a secure network whenever they travel. First, it can function as a regular router for the home, and if you already have an existing ASUS mesh network, it can work as an additional node. Second, with WISP mode, it can provide you with a private WiFi hotspot using a connection from a public WiFi. Lastly, it supports 4G/5G mobile tethering, allowing you to supply the RT-AX57 Go with mobile internet from your smartphone.
