如何修复 Ubuntu 18.04.5 LTS 以太网控制器 1 Gbps 适配器现在仅限于下载速度为 100 Mpbs？

在两台不同的笔记本电脑上，都是 HP OMEN 笔记本电脑 15-dc1xxx SKU 7TK52UA#ABA，从 18.04.3 LTS 升级到 18.04.5 打破了千兆速度。千兆速度在 18.04.3 中运行良好在运行内核 5.4.0-42-generic 时更新了几周，RTL8111/8168/8411 PCI Express 千兆以太网控制器的下载速度。下载速度现在被限制在大约 100-130 Mbps 并且上传仍然能够达到 1 Gbps (1000 Mbps)。

有AT&T Gigapower (gigabit up and down)，并更换了网关认为这是最初的问题。这已被证明不是问题的根源。

试图让 Gigabit 速度恢复而不得不回滚内核版本。

更新：笔记本电脑型号

Sku 在顶部：7TK52UA#ABA
型号：HP Omen 15-dc1057nr
内核：5.4.0-45-generic
惠普最新固件：F.18 Rev.A
https://support.hp.com/us-en/drivers/selfservice/omen-by-hp-15-dc1000-laptop-pc-series/26122182/model/30206210?sku=7TK52UA

更新：固件从 F.12 升级到 F.18 Rev. A

提醒：拥有两台 HP Omen 15-dc1057nr 笔记本电脑

一个在测试期间从 Ubuntu 18.04.5 LTS 升级到 20.04.1 LTS。

在 Ubuntu 20.04.1 LTS 上测试

状态：成功；千兆速度再次使用 BIOS F.18 Rev. A

在 Ubuntu 18.04.5 LTS 上测试

状态：失败；在 BIOS F.18 和使用 r8169 或 r8168 时
光纤/千兆连接仍然变慢
130.2 Mbps/下行和 868.6 Mbps/上行

有关 20.04.1 LTS，请参阅下面关于 r8168 的评论中的注释。

按照链接how-to中的“使用 USB 恢复驱动器恢复 BIOS”->“创建 USB 恢复驱动器”过程进行操作。

这个特殊的 HP Omen 15-dc1057nr 在 BIOS 菜单中没有用于更新 BIOS 或从本地媒体更新 BIOS 的选项。要强制 HP Omen 访问 HP BIOS 更新屏幕，请执行以下操作：

同时按住Windows键和B键。
在继续按住这些键的同时，按住电源按钮 2 到 3 秒。
松开电源按钮并继续按下Windows和B键，直到出现 HP BIOS 更新屏幕。（注意：有几次我不得不在此步骤中松开 Windows 和 B 键才能显示屏幕；请看 HP）
如果遇到任何问题，请参阅上面“使用按键组合恢复 BIOS”部分下的相同链接以进行检查。

更新：之前运行 Ubuntu 18.04.5 LTS 的第二台笔记本电脑升级了 20.04.1 LTS

从 18.04.5 LTS 升级到 20.04.1 LTS 没有问题
千兆下载速度仍限制在 ~ 130 Mbps/下
上传速度仍然 ~ 800+ Mbps/up
使用“忽略、自动和手动 1 Gb/s Full”对有线千兆连接进行测试 - 仍然不超过 ~ 130 Mbps/down
创建了现场 USB 并测试了以下内容：
- Ubuntu 18.04.3 LTS Live - 结果：850+ Mbps/下 & 900+ Mbps/上
- Ubuntu 18.04.5 LTS Live - 结果：不确定
  - 速度测试 1：907 Mbps/下行和 886 Mbps/上行
  - 速度测试 2：126 Mbps/下行和 864 Mbps/上行
  - 速度测试 3：122 Mbps/下行和 880 Mbps/上行
  - syslog 内核消息报告链接以 1 Gbps/全流控制关闭
- Ubuntu 20.04.1 LTS Live - 结果：130~ Mbps/down & 850+ Mbps/up

经验证的 BIOS 固件位于 F18：

$ sudo cat /sys/class/dmi/id/bios_version
F.18

可以肯定的是，已验证 DMI 信息等同于第 2 台 HP Omen dc-1057nr

如何修复 Ubuntu 18.04.5 LTS 以太网控制器 1 Gbps 适配器现在仅限于下载速度为 100 Mpbs？

如何运行 .sh 脚本？

如何安装 .tar.gz（或 .tar.bz2）文件？

如何列出所有已安装的软件包

无法锁定管理目录 (/var/lib/dpkg/) 是另一个进程在使用它吗？
