刚刚在 Acer Aspire S 上安装了 Ubuntu 16.04，除了 wifi 之外，其他一切都运行良好。我可以连接到开放热点，但当我在家中验证 WPA2 路由器时，它失败了。
这是 Atheros QCA6174...

似乎身份验证成功，但随后立即取消身份验证？尝试替换我的 /lib/firmware/ath10k，如https://askubuntu.com/a/718430/717711但这导致我的无线网络完全停止工作，所以我恢复了这些更改。
不幸的是我现在有点困惑。非常感谢您的帮助！

搞定了。WPA 身份验证可与其他路由器配合使用，但不适用于我家里的路由器。说清楚点...
- WPA 可与其他路由器配合使用。
- 我的家用路由器的 WPA 使用 Windows 运行。
- 我的家用路由器的 WPA 可与其他 Ubuntu 系统兼容。
- 唯一的问题在于 Ubuntu 的 Atheros 固件和这个特定的路由器。
很奇怪，但很容易修复。无论如何，这是一个旧路由器。:)
