## 常见问题

### 无法开启 5G 热点
### 1. 无法开启 5G 热点

尝试指定 `Channel` 参数为 `<A (5 GHz)> 36`

### 2. 客户端能扫描到热点但是连接失败

这是因为 `NetworkManager` 的前端描述错误导致的，加密方式选择了 `WPA2` 但是其实实际开启的的是 `WPA3`，
又因为部分网卡不支持 `WPA3`，导致只能扫描到热点但是连接失败，可通过添加以下参数关闭 `WPA3` 能力。

```
sudo nmcli connection modify <CONNECTION NAME> wifi-sec.key-mgmt wpa-psk
sudo nmcli connection down <CONNECTION NAME> connection
sudo nmcli connection up <CONNECTION NAME> connection --ask
```

## Q&A

### Can't turn on 5G hotspot
### 1. Can't turn on 5G hotspot

Try specifying the `Channel` parameter as `<A (5 GHz)> 36`.

### 2. The client can scan the hotspot but connection fails.

This is because the front-end of `NetworkManager` is wrongly described,
and the encryption method selected is `WPA2`, but the actual encryption method is `WPA3`,
and some WIFI devices do not support `WPA3`.
Because some WIFI devices don't support `WPA3`, it can only scan the hotspot but fail to connect,
you can disable `WPA3` by adding the following parameter.

```
sudo nmcli connection modify <CONNECTION NAME> wifi-sec.key-mgmt wpa-psk
sudo nmcli connection down <CONNECTION NAME> connection
sudo nmcli connection up <CONNECTION NAME> connection --ask
```
