Qualcomm Atheros 设备 [168c:0042] (rev 30) ubuntu 16.04

我有一台运行 Ubuntu 16.04（内核 4.4）的联想 i310。只有按照以下奇怪的步骤操作，wifi 才能正常工作：

  • 打开笔记本电脑

  • 按住电源按钮几秒钟

  • 再次打开笔记本电脑

硬件开关全部打开。BIOS 中已启用 Wifi。

我迄今为止注意到的差异。

命令：lspci -nnv |grep ualcom

当 Wi-Fi 无法工作时：

当 Wi-Fi 工作时：

02:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:0042] (rev 30)

命令：rfkill list。

答案1

您的lsmod意思是驱动程序模块没有按预期自动加载。让我们稍微推动一下。从终端：

sudo -i
echo ath10k_pci  >>  /etc/modules
exit

重新启动并测试。
