업그레이드된 Debian Stable(Jessie) 데스크톱은 유선 인터넷에 연결할 수 없습니다.

며칠 전 나는 Debian Jessie 설치를 새로운 Linux 커널( uname -a주어진 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u3 (2016-01-17) x86_64 GNU/Linux)을 포함하는 현재 마이너 버전(8.3)으로 업데이트했습니다. 그 이후로 이전에는 문제가 되지 않았던 인터넷에 연결할 수 없습니다. 동일한 이더넷 케이블과 포트를 Macbook이나 심지어 오래된 CentOS 컴퓨터에 연결하면 (DHCP를 사용하여) 빠르게 인터넷에 연결할 수 있으므로 문제는 Debian 구성에 있는 것임에 틀림없습니다. 하지만 어떻게 해야할지 모르겠습니다. DHCP 또는 고정 IP(다른 컴퓨터에서 DHCP를 통해 얻은 IP 주소 및 설정 사용) 및/ ifupdown또는 여러 번의 재부팅을 다양한 조합으로 시도했지만 network-manager소용이 없었습니다. DHCP는 자동으로 실패하거나 임대를 얻지 못했다는 메시지를 표시합니다. 고정 IP를 사용하면 이더넷 장치가 연결된 것처럼 보이지만 실제로는 인터넷에 연결되어 있지 않습니다. 이 문제를 해결하는 방법에 대한 아이디어가 있습니까?
