LinuxでインテルNUCの内臓Wifiが認識されない場合の対処

More than 3 years have passed since last update.

インテルの NUC NUC5i3RYHに CentOS 7をインストールしたら、内臓Wifiが認識されませんでした。ドライバが不足していたようで、追加でインストールする必要がありました。

NUC5i3RYHが搭載しているWifiはインテルの Wireless-AC 7265 で、そのドライバを探してみところ、iwl7265-firmware というのが該当するようです。

とりあえず、インストールしてみるたところ、

$ yum install iwl7265-firmware -y

無事、Wifiが使えるようになりました:smile:

$ ifconfig wlp2s0
wlp2s0: flags=4098<BROADCAST,MULTICAST>  mtu 1500
        ether 34:13:e8:1f:88:3a  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

どうやら、インテルのWifiドライバのパッケージは、iwl[チップの型番]-firmware という名前になっているようです。試しに、yum search で検索してみたら、たくさん出てきました。

$ yum search iwl

  Name and summary matches only, use "search all" for everything.

Windowsではドライバは自動的に検索・インストールされますが、Linuxの場合、比較的、新しいデバイスのドライバは自分で探して入れないといけないようです:sweat_smile:
