리눅스에서 인텔 NUC 내장 Wifi를 인식하지 못하는 경우

인텔 NUC NUC5i3RYH에 CentOS 7을 설치하면 내부 장기 와이파이가 인식되지 않았습니다. 드라이버가 부족한 것 같았고 추가로 설치해야했습니다.

NUC5i3RYH가 탑재하고 있는 Wifi는 인텔의 Wireless-AC 7265로, 그 드라이버를 찾아 보면, iwl7265-firmware 라는 것이 해당하는 것 같습니다.

우선, 설치해 보니,

$ yum install iwl7265-firmware -y

안전하게 Wifi를 사용할 수 있습니다

$ 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

분명히 인텔 와이파이 드라이버 패키지는 iwl [칩 모델 번호] - firmware라는 이름으로되어있는 것 같습니다. 시도로 yum search에서 검색해 보면 많이 나왔습니다.

$ yum search iwl

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

Windows에서는 드라이버가 자동으로 검색되고 설치되지만 Linux의 경우 비교적 새로운 장치 드라이버를 직접 찾아야합니다.
