편집 : 적절한 드라이버를 찾았습니다

https://github.com/ghostrider-reborn/realtek-r8101-linux-driver

여기 지침을 따랐고 이제 두 네트워크 카드가 모두 작동합니다 (동일한 네트워크에 연결을 테스트하기 때문에 한 번에 하나씩 만 사용합니다.)

원본 게시물

이전에 Kubuntu 14.04를 실행 한 컴퓨터에 Kubuntu 18.04를 설치했는데 두 네트워크 카드 중 하나가 성공적으로 작동하지 않았습니다. 안타깝게도 랩 설정을 위해 두 가지를 모두 구성해야합니다.

동일한 이더넷 케이블로 둘 중 하나를 연결하려고 시도했지만 RTL8111 만 작동합니다. dmesg이더넷 또는 네트워크에 대한 내용이 없으며 journalctl -xeRTL8111 드라이버의 성공적인로드 만 언급합니다.

다음은 유용하게 사용할 수있는 몇 가지 진단 출력입니다.

Kubuntu는 네트워크 카드를 볼 수 있지만 (세 번째 장치는 USB 테 더링을 사용하는 휴대폰입니다) 첫 번째는 "UNCLAIMED"입니다.
