Qualcomm Atheros 设备 [168c:003e] (rev 32) QCA6174 - 内核/固件更新后出现问题 (4.2.0-18-generic/firmware_1.149.2)

Question

我最近因为缺少 wifi 驱动程序（Qualcomm Atheros Device [168c:003e] - ath10k_pci）而更新至 4.2.0-18-generic/firmware_1.149.2。

Wifi 仍然无法工作 (即使安装了驱动程序)。

请参阅lspci-knn| grep -i 净-A2

sudo lshw -C 网络

编辑：

在 lib/firmware/ath10k/QCA6174/hw3.0 中找不到 QCA6174 的 firmware-5.bin。因此我从 hw2.1 文件夹中复制了它。另一件事是缺少 ath10k.conf。

sudo nano /etc/modprobe.d/ath10k.conf

"options ath10k_core skip_otp=y"

但重启后仍然没有 wifi。

    dmesg | grep ath10k

Answer 1

现在似乎有一个答案/或至少有一个解决方法-对我来说有用。

感谢丹尼斯。

将其复制到 /lib/firmware/ath10k/QCA6174/hw3.0/ 时，请注意文件命名正确。
