無法啟動 Realtek r8168 乙太網卡

我在 Arch Linux 上工作，99% 的時間我通過 WLAN 連接到網際網路，但有時我需要使用乙太網連接，所以今天我看到了一些奇怪的東西。我的 eth0 設備已關閉，無法啟動。我試過了

# ip link set eth0 up
# ifconfig eth0 up

但是在上述任何命令ip link顯示後：

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

似乎 RealTek 8168B 在 Debian Squeeze 上存在問題。試試那些：

• 如果您遇到網路介面無法使用 RealTek 8168 的問題，這可能會有所幫助並提供洞察力（即 realtek 韌體問題）： https ://serverfault.com/questions/384165/after-installing-debian-squeeze-ethernet -不上來
• 如果您的核心甚至沒有載入正確的模組 = RealTek 8168 的驅動程序，這可能會提供必要的見解（即硬體檢測問題）： http ://djlab.com/2010/10/fixing-rtl8111-8168b-驅動程序-debian-ubuntu/
