매번 "ethtool"을 수동으로 실행하지 않고 자동으로 인터넷 연결을 시작하는 방법

Linux가 부팅될 때마다 아래 두 명령을 수동으로 사용하여 인터넷에 연결해야 합니다.

ethtool -s eth0 autoneg off speed 100 duplex full

ifup eth0

부팅 후 바로 실행 하면 ethtool eth0문제가 다음과 같이 설명됩니다 Link detected: no. https://paste.debian.net/hidden/d2b0d461/

이 라우터의 케이블을 이전 DSL 라우터 연결(다른 ISP이지만 Linux 컴퓨터에 동일한 이더넷 케이블을 사용하더라도)로 변경하면 동일한 Linux 컴퓨터가 재부팅 후 인터넷 연결을 수신하므로 다른 추가 명령이 필요하지 않습니다.

Lubuntu가 부팅될 때 자동으로 인터넷 연결을 시작하는 방법을 찾고 있습니다.

이것이 어떻게 발생하는지 아신다면 동일한 머신 + 동일한 OS(Linux의 경우 구성 변경 없음) + 동일한 이더넷 케이블이 항상 자동으로 인터넷을 "수신 및 유지"합니다(추가 수동 명령 없음). 3가지 다른 라우터 모델 모두에 대해.

네 번째 문제가 있는 연결 및 라우터를 제외하고 3개의 연결 및 라우터는 모두 동일한 ISP에서 제공됩니다.

최고의 소원.
