Centos7にワイヤレスネットワークアダプターをインストールします

Centos7と最新のカーネル4.7.3-1.el7.elrepo.x86_64を搭載したAcerAspiree5-575g-53vgラップトップを持っています。 Acerによると、私のワイヤレスアダプタはIntel Wireless-AC 7265（ラップトップを分解せずにこれを確認する方法はありますか？）ですが、lspciはこのデバイスを表示していません。 linux drivers をダウンロードして、サイトに記載されているように/ lib/firmwareに入れましたが、次に何をすべきかわかりません。

私も これらの指示 を試しましたが、

nmcli con

戻り値

これは、新しいwlp2s0接続からデバイスが欠落していることを示しています。

以下はlspci -vの出力です。

セルジュは私を案内し、この問題を解決しました。

まず、私のワイヤレスアダプターはQualcomm Atheros Device 0042（rev 31）です。 このガイド から3行を取る

git clone https://github.com/kvalo/ath10k-firmware.git
Sudo cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k/
Sudo cp /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin

その後、再起動すると問題が解決しました。

事前にパッケージ化された3.10カーネルで上記の手順を実行しても機能しないことに注意してください。これを機能させるには、4.7に更新する必要がありました。
