这是我使用了两年的 Windows 10 桌面。大约 6 个月前，USB Wi-Fi 适配器在登录后开始断开连接，需要手动断开连接并重新连接才能重新开始工作。每次登录时这种情况只会发生一次，我已经习惯了，然后就不再管了。
从周一开始，我就无法通过 USB 适配器连接互联网超过几秒钟（而且速度很慢）。路由器对于所有其他连接的设备来说都很好。

任何关于如何解决这个问题的想法都将不胜感激，它已经从令人烦恼变成了完全无法使用。
另一个线程建议禁用 WAN Miniport IP 设备devmgmt.msc。这不起作用，我在 ping 路由器时仍然看到“无资源”。
切换到主板内置的无线适配器，它可以连接到互联网，但速度非常非常慢（因此使用 USB 适配器已有 2 年）。当 ping 默认网关时，会出现类似的数据包丢失...
