私は最近、wifiドライバーが欠落しているため(Qualcomm Atheros Device [168c:003e]-ath10k_pci)4.2.0-18-generic/firmware_1.149.2に更新しました。
Wifiはまだ動作していません(ドライバーを使用しても)。

QCA6174のfirmware-5.binがlib/firmware/ath10k/QCA6174/hw3.0に見つかりませんでした。そのため、hw2.1フォルダーからコピーしました。もう1つは、ath10k.confが欠落していることです。
Sudo nano /etc/modprobe.d/ath10k.conf
"options ath10k_core skip_otp=y"
しかし、再起動後はまだ無線LANがありません。

今すぐ答えがあるか、または少なくとも回避策があるようです-私のために働いた。
デニスに感謝します。
