“回收”戴尔 LAN 上的 Ubuntu 服务器速度被限制为 100mbp/s

“回收”戴尔 LAN 上的 Ubuntu 服务器速度被限制为 100mbp/s

我在一台改装的 2011 年戴尔塔式机上安装了 Ubuntu 服务器 19.04。
以前是 Windows 系统,在 ETH 有线局域网上我的网速是 1Gbp/S,但现在在 Ubuntu 上它无法识别硬件。

尝试更新固件,也弄乱了 BIOS,电缆和路由器都功能齐全(现代设备)

正在做sudo lshw -C 网络返回没有什么.
简单运行须藤lshw返回完整的规格列表,在 *-core 下我们可以看到:

我知道你们中的一些人可能会说“没有1000baseT所以是不可能的......“但我很肯定硬件是千兆兼容的。
