1.启用无线网卡

重置配置文件，如果是新系统没有进行过相关设置可以跳过

rm -f /etc/config/wireless; wifi config instead

启用无线网卡

uci set wireless.@wifi-device[0].disabled="0"
uci commit wireless
wifi

提示：这里是设置第一块无线网卡。

如果要设置第二块网卡，如下操作

uci set wireless.@wifi-device[1].disabled="0"
uci commit wireless
wifi wlan1

2.无线网络设置

执行

iw dev

命令显示如下格式信息

phy#0
        Interface wlan0
                ifindex 5
                wdev 0x1
                addr ab:12:23:dc:03:45
                type managed
                txpower 20.00 dBm

搜索无线网络

iw dev wlan0 scan

显示如下格式无线网络信息，若有多个无线网络，会显示多个这样格式的信息
