[Ubuntu] 내 노트북에서 와이파이 핫스팟을 지원하는지 확인하기


PC: Dell Vostro V13



1. 커맨드 입력창에서 다음과 같이 입력한다.
    (커맨드창 단축키: Ctrl + Alt + T)

$ lspci | grep -i Network
$ ethtool -i {본인의 와이파이 네트워크 이름} | grep driver


PS. 

ifconfig 명령어를 입력하면 네트워크 이름을 알아낼 수 있다.
(보통 wlan0 이 일반적이다.)

나의 경우에는 와이파이 어댑터가 [Intel] 제품에 [iwlwifi] 드라이버를 사용하는것으로 나온다.
아래의 표를 보면 내 제품은 AP를 지원하는 것으로 보여진다.
드라이버 링크를 눌러 들어가니 일부 모델/펌웨어 에서만 지원된다고 기술되어 있다.

정확하게 알아볼 수 있는 방법은 다음과 같다.
아래와 같이 입력 후 'Supported interface mode' 부분에 AP 가 있다면 AP모드를 지원한다.
(안타깝게도 내 노트북의 무선네트워크는 지원하지 않는다. ㅠㅠ
리눅스 무선네트워크 펌웨어를 변경하면서까지 몇시간동안 방법을 찾아봤지만 리눅스 에서는 방법이 없었다.
결국 윈도우 설치 후 AP를 설정하고야 말았다.
