hotspot by connecting it to your laptop with the USB cable to
access the Internet.
Additional features include:

display settings, view data usage details, view system and
network provider messages.
• Wi-Fi Protected Setup (WPS) — A fast, easy way to connect
WPS-enabled devices to your Wi-Fi network.
• Guest Wi-Fi — Set up a guest Wi-Fi network for temporary
users, and use the main network for trusted devices.
