我试过iw dev wlp3s0 set reg BO

命令返回成功

但实际上并没有改变reg

这是日志：

Answer 1

许多国家都在限制不断变化的监管领域。 如果驱动程序不支持此功能，也是不可能的。

如果这个命令不适合你iw dev wlp3s0 set reg BO

那么你可以尝试这种方法

git clone https://github.com/robertfoss/wireless-regdb.git
cd wireless-regdb.git
make
# edit db.txt file with your required country
./db2bin.py
# overwrite /lib/crda/regulatory.bin with new generated file
cp regulatory.bin /lib/crda/regulatory.bin

某些国家/地区不允许将频率更改为高于12（频道）。使用风险由您自行承担。
