in both ways. During the setup steps, select the Wi-Fi option that suits you
best:
Client (Infrastructure): Select if you will only be connecting to this
device over your Wi-Fi network.
Access Point: Select if you will only be connecting directly to this
device’s built-in WiFi hotspot.

TIP: Benefits of Access Point mode
ProfiLux 4 is equipped with its own Wi-Fi hotspot which emitts a Wi-Fi signal
for other devices (PC, Smartphone, Tablet) to connect to it. This is called
Access Point Mode . This feature is especially useful if your primary internet
goes down. With Access Point or Client/AP mode , you can still connect to
your P4 by searching for nearby Wi-Fi networks and selecting the P4’s WiFi
hotspot.
