本文展示了如何使用iwinfo命令在OpenWrt系统中获取无线设备（如wlan0）的信息，包括设备状态、扫描SSID、查看发送功率、信道列表、关联的终端信息以及国家列表。此外，还提供了切换到monitor模式的步骤。

root@hbg:/# iwinfo -h

Usage:

iwinfo <device> info // 查看设备信息

iwinfo <device> scan // 扫描周围ssid

iwinfo <device> txpowerlist // 设备发送功率及当前的使用功率

iwinfo <device> freqlist // 设备的信道以及当前使用的信道

iwinfo <device> assoclist // 关联的终端信息

iwinfo <device> countrylist // 国家信息

root@OpenWrt:~# iwinfo wlan0 assoclist
