Joh*_*ohn 2 networking intel drivers 20.04
基于技嘉 z490 Vision G 主板的全新构建。网络链接灯亮起，电缆直接连接到交换机。我安装了另一个网卡，连接到同一个交换机，这就是我用来连接的，因为它工作得很好（英特尔 igb 驱动程序）。板载网络端口偶尔会在重启后出现，但通常显示没有链接和速度/双工“未知！”
你认为这是怎么回事？您还需要什么信息？
我不认为这是 cat6 电缆，我尝试了多个和多个交换机端口，以及在其他端口上成功使用的电缆。这是一个连接到 1Gbps 交换机的 2.5Gbps 网卡，我可以尝试拿起一个 cat7，看看是否有帮助。
最后附加了请求的数据，没有 /etc/network/interfaces 目录，并且 /etc/network 下的所有内容看起来都很正常。
Ubuntu 20.04 服务器安装。

我会回答我自己的问题，这是英特尔固件问题。希望这对其他人有帮助。
技嘉在其网站上发布了一个仅限 Windows 的 NIC 固件，https://download.gigabyte.com/FileList/Driver/mb_driver_intel-i225-firmware-tool.zip。英特尔在他们的网站上有 Linux NVMUpdate 实用程序，但据我所知，没有与这个固件一起打包。可在https://downloadcenter.intel.com/download/22283/Intel-Ethernet-Adapter-Complete-Driver-Pack 获得
因此，下载两者，将 FXVL_15F3_V_2MB_1.45.bin 从 Windows 更新程序复制到 linux 位置，在我的情况下：
cp ~/Nvmupdate145/i225/FXVL_15F3_V_2MB_1.45.bin ~/NVMUpdatePackage/700_Series/700Series/Linux_x64
将此添加到 nvmupdate.cfg：
BEGIN DEVICE
DEVICENAME: NNT
VENDOR: 8086
DEVICE: 15F3
SUBVENDOR: 1458
SUBDEVICE: E000
NVM IMAGE: FXVL_15F3_V_2MB_1.45.bin
IMAGE DOWNGRADE: TRUE
END DEVICE
并运行该实用程序。你应该看到：

基于上面答案的启发，对于在带有 Intel I225-LM 芯片组的 Asus WS X299 SAGE II 主板上运行的 Ubuntu 20.04.1 系统，我切换到 5.8.7 主线通用内核（最新的 5.8 行）撰写本文时）使用内核 PPA 构建。（步骤受此处文章的启发）。
\n您\xe2\x80\x99需要从此处下载以下文件：
\nlinux-headers-*all.deblinux-headers-*generic*.deblinux-image-unsigned-*generic*.deblinux-modules-*generic*.deb下载完\xe2\x80\x99后，运行sudo dpkg -i deb linux*.deb
重启！（例如sudo reboot）
一旦系统备份并运行，您可以通过运行以下命令来验证内核 5.8.7 上的\xe2\x80\x99reuname -sr
这样做解决了我的内置网卡遇到的问题，并且整个系统在高内存和 CPU 压力下连续几天保持稳定，没有出现问题。
\n我最初尝试采用固件更新路线，但由于我有 I225-LM 而不是 I225-V，因此受到阻碍。后者似乎已经更新了固件，可以将其引入 Linux 环境，而我无法\xe2\x80\x99 为前者找到类似的结果。
