1. network-manager 預設同一個時間只能有一條 route 有效

尝试安装以太网卡驱动失败，详情如下。

1. 下载r8168-8.040.00http://www.realtek.com.tw/downloads/dow ... ERTL8118AS

2. 按README要求运行：

Check old driver and unload it.

1. lsmod | grep r8169
看看是否還在
1-1. 補充如果還在要先將 r8169 模組卸載或列入載入黑名單
重新開機再執行
sudo ./autorun.sh
以免 r8169 干擾

在READMD中给出了安装要求：

代码：全选

      
        - Kernel source tree (supported Linux kernel 2.6.x and 2.4.x)
        - For linux kernel 2.4.x, this driver supports 2.4.20 and latter.
        - Compiler/binutils for kernel compilation

检查已安装binutils。删除了/lib/modules/3.16.0-4-amd64，再次编译提示如下错误：

r8168，不要编译安装，管理麻烦。直接到软件源安装 r8168-dkms
注意，Jessie中不知何故没有 r8168-dkms，可下载 sid 的包安装，没有一点问题：http://ftp.cn.debian.org/debian/pool/no ... -1_all.deb

1.
先把无线网卡断开，再解决有线：
网线拔出，打开终端，输入

代码：全选

sudo journalctl -f

滚动监视系统日志。
插入网线，令其连接，观察新产生的日志输出。这样才能定位问题出在哪一层：驱动问题？NM 问题？dhclient 问题？......

状态栏中的网络图标一直显示正在连接

看此时日志卡在哪里？
可以把插入网线后新产生的日志输出全发上来。

2.
r8169 驱动有时会产生诡异的问题。可安装 r8168

代码：全选

wget http://ftp.cn.debian.org/debian/pool/non-free/r/r8168/r8168-dkms_8.040.00-1_all.deb
dpkg -i r8168-dkms_8.040.00-1_all.deb

注意，Jessie中不知何故没有 r8168-dkms，可下载 sid 的包安装，依赖干净，没有一点问题：http://ftp.cn.debian.org/debian/pool/no ... -1_all.deb
dkms 的好处是较为智能，内核升级无痛重编译。手动编译安装的就得自己费心。

感谢poloxiao和vickycq的持续关注和帮助。看来确实是以太网卡的驱动没装对，参考http://dwaves.de/2013/12/31/debian-inst ... ck-e350m1/安装上了驱动。网卡需要的固件是rtl8168e-3.fw。现在以太卡和无线卡都装上了。谢谢！

通过和二位的请教，发现很多概念都很模糊。还要慢慢学习。

dkms source for the r8168 network driver

@poloshiao, 安装后可自动编译, depmod, mkinitcpio, blacklist r8169, insmod ... 每次升级内核均会自动重复以上步骤，保证无痛衔接。可谓是内核模块驱动的傻瓜一站式管理方案

不过目前 debian 中只有 sid 套件库有此包，迟迟不能进入 testing/stable，或许是有 release-critical bug. 不过我没有遇到，工作十分稳定。此包依赖简单 <dkms (>= 2.1.0.0)> ，完全可用于从 jessie 到 sid 各版本。

1. 謝謝提醒
我的 RTL8111/8168/8411 主板報銷了
所以現在無法實作驗證

2. 有許多無線網卡還需要額外安裝合適版本的 firmware 才能正常運作

谢谢提醒
网卡的二进制固件在debian中为独立打包，且默认不安装。如 firmware-ipw2200, firmware-ralink, firmware-realtek 等。楼主的情况需要安装 firmware-realtek 以发挥最大效果。
