news 2026/2/7 12:53:11

格式说明

RTL8192cd 驱动程序提供 MIB 接口，可通过“iwpriv”命令获取/设置参数。

set_mib

iwpriv set_mib name=value1[,value2,value3…]”

Iface: “wlan0”

value:

1.值可以是单个字段，也可以是用“，”分隔的多个字段，字段之间没有任何空格

2.如果值是字节数组的类型，则值的格式将是 0~f 的 ASCII 字符串，其中使用 2 ASCII 代表一个字节。

例如，设置WiFi path A的CCK的TXPower

iwpriv wlan0 set_mib pwrlevelCCK_A=08080909090a0a0a0a0b0b0b0c0c

说明：后面表示1~14信道的功率索引值，08表示信道1的
