我的 Dell Latitude 5420 出现了问题。我的互联网连接在 Windows 10 下运行良好,但当我使用 Ubuntu 20.04.3 LTS(桌面版)或 OpenSUSE Leap 15.3(桌面版)时,我的 Wi-Fi 连接正常,但以太网连接则不行。
使用以太网时,我的下载速度为 2 或 5 Mb/s,使用 Wi-Fi 时,我的下载速度为 100 Mb/s。
我的以太网上传速度为 200 Mb/s,Wi-Fi 上传速度为 100 Mb/s。
如您所见,以太网上传正常,但下载却不行。

您能帮我解决 Dell Latitude 5420 上的这个问题吗?
供参考:我见过以太网连接的宽度,它是 32 位而不是 64 位,我不知道,因为这种情况会发生。唯一引起我注意的是驱动程序,它是 e1000e。我猜系统正在使用这个通用驱动程序,因为它找不到其他任何东西。看来那是网卡。我见过 DELL页下载适用于 Ubuntu 20.04 LTS 的驱动程序,但只出现用于更新 BIOS 的驱动程序。
我希望有人能帮助我。非常感谢!
