## 去除原生系统Wi-Fi及蜂窝网络叹号

```bash
adb shell "settings put global captive_portal_http_url http://www.google.cn/generate_204"
adb shell "settings put global captive_portal_https_url https://www.google.cn/generate_204"
```

其中captive\_portal的url也可以换成任意能生成204状态码的地址，例如<http://connect.rom.miui.com/generate_204>、<https://captive.v2ex.co/generate_204>等，小米MIUI的portal地址在中国大陆也很稳定。
