昨天某个时候,我丢失了有线以太网连接。它不再出现在网络管理器中,似乎也不再处于活动状态ifconfig
,但无线适配器处于活动状态。
可能的线索:这似乎是在网络管理器(1.22.10-1ubuntu2.2/3)更新后不久发生的,但也有内核更新(5.4.0-97.110)和 system76 驱动程序(20.04.47~1641830102~20.04~12f1c0f~dev、20.04.48~1643752136~20.04~8120238~dev)。
尝试缓解措施:我尝试安装描述的脚本这里,描述的r8168-dkms内核模块这里,并进行完全关闭并重新启动,但无济于事。
可能相关命令的输出:
sudo lshw -C network

答案1
我无法解释为什么这是必要的,但解决方案归结为确保有线接口是“可管理的”。我/usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf
从以下方面进行了更改:
[keyfile]
unmanaged-devices=*,except:type:wifi,except:type:gsm,except:type:cdma
到:
[keyfile]
unmanaged-devices=*,except:type:wifi,except:type:gsm,except:type:cdma,except:type:ethernet
现在我的有线接口立即可用。无需新的电缆、驱动程序或脚本。
