我使用 Orange pi Zero 2 作为家庭服务器/媒体中心，并使用 Orange pi 发布的 ubuntu jammy 版本。 (Orangepizero2_3.0.6_ubuntu_jammy_server_linux5.16.17)
几周前，当我在电视上观看存储在该服务器上的视频时，我的以太网连接停止工作。
如果更有经验的人能给我一些反馈，我将不胜感激。
我是一个非常基础的 Linux 用户，我尝试了在互联网上的各个论坛上找到的很多东西。不幸的是，到目前为止我还没有取得很大的成功。
我最终再次烧毁了我的 SD 卡以重新启动，即使这样也没有让我的以太网正常工作。这就是为什么我开始相信以太网控制器在使用大约 1 个月后就烧毁了..:(
我什至不确定哪些命令结果与此处显示相关，但无论如何我都会在下面复制其中的几个结果。
噗。
