iptime A3000PX 무선랜카드를 샀는데, (누군가는 플러그앤 플레이를 지원한다고 하였지만) 윈도우와 우분투 양쪽에서 모두 바로 사용이 불가한 문제 발생.
하드웨어 인식 자체는 되었으나, 사용할 준비까지는 되지 않은 상태이므로 드라이버가 필요해 보임.
윈도우에서는 iptime 쪽에서 제공하는 드라이버로 해결. 하지만 우분투용 드라이버는 제공하지 않음
따라서, 아래 링크에 있는 설명을 따라 해결
https://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers
나의 경우 usb방식의 저가 랜카드가 있어 인터넷이 되긴 하니 online 설치 방식을 택하였지만, 그렇지 않다면 인터넷이 되는 다른 PC에서 다운을 받아와야 할 듯 함.
터미널 창에서 아래를 실행
lspci -nn -d 14e4:
나의 경우 아래와 같은 메세지 확인
0a:00.0 Network controller [0280]: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter
[14e4:43a0] (rev 03)
여기서, 메세지 끝단에 있는 [14e4:43a0]가 중요. 이를 아래 테이블에서 찾아야 함.
나의 경우, bcmwl-kernel-source 라고 써있으므로 sudo apt install bcmwl-kernel-source 을 실행.
재부팅 하면 무선랜카드 정상적으로 사용 가능
PCI.ID 16.04 LTS 17.10+
