我的计算机 (HP ProBook 455 G1) 内置有 Realtek RTL8168 以太网卡，运行 Linux Mint 17.2 Cinnamon 64 位。
在您告诉我用Realtek 网站上的r8169模块替换预装模块之前，让我告诉您我已经这样做了。r8168我从Realtek的网站下载了8.040.00版本，这是R8168系列驱动程序的最新版本，编译并安装它，列入黑名单r8169并加载r8168。
从那时起，我可以全速浏览（ISP 限制为 15 MB/s），但连接经常断开。只有拔出以太网电缆并重新插入，我才能恢复连接。很多人建议重新启动 NetworkManager 服务，而不是重新插入电缆，但没有任何效果。
此外，据我所知，我认为没有任何日志文件具有相关性，无论是/var/log/dmesg还是/var/log/kern.log和/var/log/syslog。不过，我还是会将其中的一部分添加到问题中。
到目前为止，我在网上找到的所有内容都是一堆独立的帖子，都在说如何替换r8169为r8168.所以我在那里找不到任何帮助，因为我已经这样做了。
