我对 Linux 真的很陌生，每天都在尝试多了解一点，并考虑参加一些课程来增加我的知识。
我一直在考虑永远放弃Windows并切换到Linux，几天前终于决定了。
最近我的互联网连接出现了一些问题，有时会出现几分钟的延迟峰值，然后逐渐减少，直到它消失并再次开始延迟。
起初我以为是我的以太网驱动程序有问题，所以我寻求帮助：
做过ifconfig

和lshw -class network

如您所见，驱动程序显示了过时的固件
问题是，我找不到合适的驱动程序，即使在 realtek 网站上也是如此。
我检查了lspci | egrep -i --color 'network|ethernet'
并显示03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c)
看到一个类似的帖子[互联网无法正常工作？] 但它似乎是一个不同的版本。Ubuntu 软件工具不显示其他更新。
感谢您的帮助，请记住我是 Linux 新手，将尽我所能遵循每一个给予的帮助。
