Qualcomm Atheros Device [168c：0042]（rev 30）Ubuntu 14.04が機能しない

Lenovo ideapad 300ラップトップを購入し、Ubuntu 14.04をインストールしました。ラップトップのwifiカードはQualcomm Atheros Device [168c：0042]（rev 30）です。

後で14.04サーバーで実行されるソフトウェアを実行しているため、15.04または15.10にアップグレードしたくないので、開発環境をランタイム環境に近い状態に保ちたいと思います。

私はNdiswrapperがここで動作しないことを読みました- Ndiswrapperは動作しません

次に、ここでJeremy31の答えを見つけました- バックポートのインストール

Jeremy31の回答でコマンドを実行して再起動しましたが、変更はありませんでした。コマンドを実行した後、dmesg | grep ath10kは何も与えませんでした。 Sudo modprobe ath10k_pci && dmesg | grep ath結果は関係ありません：

[    0.643855] Loaded X.509 cert 'Magrathea: Glacier signing key: e09b1e7e9841e9cfef256b70ab210562dab1ef68'
[ 4855.547585]  [<ffffffff81074dea>] warn_slowpath_common+0x8a/0xc0
[ 4855.547587]  [<ffffffff81074e66>] warn_slowpath_fmt+0x46/0x50

この問題を解決するための助けをいただければ幸いです。前もって感謝します

を使用してバックポートを再インストールします

cd backports-20151120
make clean
make
make defconfig-ath10k
Sudo make install

再起動して、modinfo ath10k_pciのファイル名が/lib/modules/3.19.0-43-generic/kernel/updates/ath10k_pci.koの場所を示しているかどうかを確認します
