无法启动 Realtek r8168 以太网卡

我一直在 Arch Linux 上工作，99% 的时间我通过 WLAN 连接到互联网，但有时我需要使用以太网连接，所以今天我看到了一些奇怪的东西。我的 eth0 设备已关闭，无法启动。我试过

# ip link set eth0 up
# ifconfig eth0 up

但在上述任何命令ip link显示后：

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN mode DEFAULT 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT qlen 1000
    link/ether 8c:a9:82:01:13:6e brd ff:ff:ff:ff:ff:ff
5: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT qlen 1000
    link/ether 14:da:e9:0c:a9:d6 brd ff:ff:ff:ff:ff:ff

输出lspci -v：

答案1

看来 RealTek 8168B 在 Debian Squeeze 上有问题。尝试一下：

答案2

我在同一适配器上遇到过一些类似的问题，原因不明。唯一的解决方案是关闭机器电源，仅重新启动、卸载模块或通过/sys接口进行各种“重置”都无法解决问题。

安装从 RealTek 下载的驱动程序（而不是普通内核中包含的驱动程序）似乎会导致问题较少发生。
