我有一个问题，在 Xubuntu Xenail 上使用华为移动 Wifi (e5220) 设备时无法上网，它是一种 USB 热点设备，可以自行连接到 3G+ 频段上网，并充当 wifi 设备可以连接的路由器。在 Windows 和 Puppy Linux 上，它运行良好，据我所知，它通过 USB 使用以太网协议，因此在 Windows 上它显示为另一个以太网连接，但在 Puppy Linux 上它被视为 wwan0，无论哪种情况，它都是在自己拨号时工作的，而不是在我必须指定 APN 或任何像普通宽带适配器一样的东西时。
我已经让它在 Xubuntu 上将其检测为宽带适配器，因此我可以看到正确的 ISP 名称和信号强度，但是无论我怎么尝试，如果我添加连接，它都无法完成连接，当然也无法上网。
以下是脚本中的信息：
