我装的双系统arch+Win11,Windows上的WiFi信号为满格,到arch这边信号就变成了一格而且容易掉,后来才了解到是网卡默认开启了节能模式然后我
```
➜ ~ iwconfig
lo no wireless extensions.
enp2s0 no wireless extensions.
wlp3s0 IEEE 802.11 ESSID:"CMCC-RAQg"

```
正当我想关闭节能模式时报错了
```
➜ ~ sudo iwconfig wlan0 power off
[sudo] crany 的密码:Error for wireless request "Set Power Management" (8B2C) :
SET failed on device wlan0 ; No such device.
➜ ~
```
接着我又查了点帖子了解到可以通过`iw`命令关闭但它又报错了
```
➜ ~ sudo iw dev wlan0 set power_save off
command failed: No such device (-19)
➜ ~
```
有大佬可以帮我吗,arch下的WiFi真是太难用了

什么网卡和驱动啊?另外推荐使用5G频段。

3.5G频段具体怎么操作或者我应该用哪些关键词搜索帖子呢

如果你的AP对不同频段使用不同的接入点名称,那么你只需要连接到5G的那个即可。否则你需要指定频段,wpa_supplicant 支持,但是上层的网络管理工具鲜少有支持的。我自己 patch 了个 netctl 在用。
