我无法使用 ubuntu(内核 4.4.0-22-generic)启动并运行笔记本电脑 WiFi。
我有一个 Qualcomm Atheros 168c:0042 pci 适配器。
我已经尝试过的事情:
- 该问题的解决方案(从 git repo 安装固件): Qualcomm Atheros Device [168c:0042] (rev 30) Wi-Fi 驱动程序安装
- 我还尝试使用另一个内核(4.5 和 4.6),结果也不错。有一个菜单可以用来连接 WiFi,但我仍然无法使用连接(没有互联网)。
- 安装反向端口(如上面的问题所述)
- 格式c:
有什么新东西我可以尝试吗?我有点绝望,因为我已经在这件事上投入了大约 8-10 个小时 =/ 任何帮助都值得感激!

将内核升级到 linux-image-extra-4.13.0-1005-azure-edge
第一次就成功了:-)
