Oneiric에서 작동하도록 이더넷 연결을 시도하고 케이블을 연결하면 영원히 연결되고 연결이 끊어집니다. /var/syslog는 다음과 같이 말합니다(반복적으로 반복).

답변1
제가 틀렸다면 정정해 주세요. 하지만 공유 연결을 사용하려고 하시는 것 같습니다. 이와 관련하여 oneiric에는 버그가 있습니다. 해결 방법과 버그 링크에 대한 다른 답변을 살펴보십시오. 다른 컴퓨터와 공유되는 유선 연결이 nm 애플릿에서 연결되었다가 연결이 끊어집니다. 해결 방법은 연결을 편집할 때 IPv6을 무시하도록 설정한 다음 sudo killall dnsmasq를 수행하는 것입니다.
답변2
Ubuntu11.10에서 임시 무선 인터넷 공유를 제공하려고 할 때도 같은 일이 발생하며
sudo killall dnsmasq마침내 도움이 되었습니다.
답변3
LAN 아이콘을 클릭하여 드라이버를 진단하고, 네트워크 공유를 열고, 로컬 영역 연결, 진단을 클릭합니다.
그것은 나를 위해 고쳐졌습니다. 이렇게 하면 LAN 어댑터가 재설정되어 정상적으로 작동하게 됩니다.
