我有一个旧的 3g usb 加密狗，用来连接互联网，SIM 卡很多年前就过期了，但我记得加密狗可以连接到 wifi。
我重新启用了没有无线网卡的旧台式机，所以我的问题是，我可以用我的 USB 适配器连接到 wifi 网络吗？如果可以，我该如何将其配置为天线而不是 3g 适配器？
我是新手，缺乏 IT 经验，所以请耐心等待。

答案1
我假设您使用的是 Ubuntu。配置 3G 加密狗以连接到 WiFi 网络，在许多情况下，需要使用加密狗附带的官方软件。
同样，在许多情况下，该软件仅适用于 Windows。您可以通过 Wine 在 Ubuntu 中安装加密狗软件，但我认为一切并非都正常工作。
因此，您可以通过软件界面操作设置，例如连接到 WiFi 网络，甚至配置加密狗 SD 卡插槽的使用。
您可以在虚拟 Windows 环境中运行该软件，以查看加密狗软件的设置是否支持连接 WiFi，以及是否有配置选项。
