linux 랜카드(wifi) 모델 확인하기(lshw -C network)
기본적으로 리눅스에서 네트워크 모델 확인 하는 방법은 lspci 를 이용한다.
# lspci
하면 위와 같이 나온다.
# lspci | grep Ethernet
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
하면 네트워크가 1개 밖에 안나오는데
# ifconfig

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 26331 bytes 1615826 (1.5 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
위와 같이 랜카드가 2개가 나온다.
이럴 경우는
# lshw -C network 명령어를 쓰면
이렇게 안보이던 카드를 확인 할 수 있다.
