https://wiki.debian.org/WiFi/HowToUse How to use a WiFi interface This page describes how to configure a WiFi interface on a Debian system, for use on a network. Once your wireless device has an interface available (verifiable by running "ip link show"), it is required to be configured to access a network. If you do not have a wireless interface present, please refer to WiFi for information on obtaining a driver, or the necessary firmware for your device. Wireless network interface configuration requires a backend, generally wpa_supplicant (often in conjunction with ifupdown and other utilities) or IWD. These can be used with connection managers that provide advanced functionality, and an easier way to configure them. Examples of these would generally be NetworkManager , ConnMan, systemd-networkd, and Wicd. The WEP algorithm is insecure and deprecated by WPA . Use of WEP is not recommended and is not covered within this document. 차례 How to use a WiFi interface A
