症状是这样的，如果我选择内核版本 5.4.XI，则会有一个网络接口连接到我的路由器（它在主板上），如果我选择内核 5.8.XI，将没有网络接口，也无法连接到我的家用路由器。
我希望新版本的内核能够解决我的问题。但目前还没有。我担心被迫迁移到某个内核版本，导致我无法在这台机器上访问互联网。
我的主板是 MSI x470 gaming pro。
有任何想法吗？
这是内核列表。目前只有 5.4.0-73 可以正常工作。
在 5.8.x 内核上，该设备不可用于连接（空设备列表）。
根据要求我在两个内核上运行了以下命令：
lsmod
sudo journalctl -b 0 -u NetworkManager
sudo lshw -C network
cat /etc/network/interfaces
cat /etc/netplan/*.yaml
dkms status
sudo dmidecode -s bios-version
$ uname -r
5.4.0-73-generic

答案1
您的以太网接口 enp34s0 确实在工作，并获取了 IP 地址 192.168.50.250。但是，sudo lshw -C network设备显示为 UNCLAiMED。
笔记：编辑您的问题并给我看cat /etc/NetworkManager/NetworkManager.conf。
笔记：试试看sudo ifconfig enp34s0 up。汇报。
