DELL1427笔记本联网问题

[evanchan]

直接安装在dell1427笔记本上的ubuntu kylin 14.04 LTS,有线只能固定IP上网。可能安装系统的时候没有联网，导致没有无线网卡驱动，所以现在也不能连WIFI。希望有大神能帮我一把，在此先行谢过了！以下是我参照这里类似的问题所执行的指令（粗体），希望能够有用。

参考这个帖子，有线网卡型号和驱动不匹配，需要手动安装正确的驱动：

不出所料，应该是你的网卡使用了错误的驱动，见红色字体的内容：

你的网卡是“RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller”，不应使用r8169这个内核驱动模块来驱动，否则就出现象你现在这样拿到了dhcp的ip地址，但网卡却一直处于不断“r8169 0000:03:00.0 eth0: link up”的状态。这样是无法使用有线网络的。

正确的驱动要到realtek的网站下载，自己安装。
http://www.realtek.com.tw/downloads/dow ... wn=false#2

选择上面这个链接中unix条目下那个“LINUX driver for kernel 3.x and 2.6.x and 2.4.x”、版本为“8.038”的文件下载。下载好文件，解压到你的家目录中，然后在家目录中执行以下命令：

代码： 全选

cd r8168-8.038.00
sudo ./autorun.sh

驱动安装完成，重启系统。你的有线网络就应该正常了。

如想确认新的驱动的情况，执行

代码： 全选

sudo lshw -C network |grep r8168

在输出中如果看到“driver=r8168 driverversion=8.038.00-NAPI”，那么就说明系统已经使用了正确的驱动了。

按照这个回复安装好驱动后表示还是不能有线联网。。。另外执行
代码:
uname -a
lspci
sudo lshw -C network
ifconfig
ping 192.168.1.1 -c 4
tail /var/log/syslog -n 20

eth0 有驅動 但是沒有獲得 IPv4

2. 所以 119.78.236.172 無法 ping 通

3. 目前作用中的驅動 r8168 可能還不是合適的驅動 版本 或 還未正確設定
正確設定值 應該是 duplex=full

不出所料，应该是你的网卡使用了错误的驱动，见红色字体的内容：

你的网卡是“RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller”，不应使用r8169这个内核驱动模块来驱动，否则就出现象你现在这样拿到了dhcp的ip地址，但网卡却一直处于不断“r8169 0000:03:00.0 eth0: link up”的状态。这样是无法使用有线网络的。

正确的驱动要到realtek的网站下载，自己安装。
http://www.realtek.com.tw/downloads/dow ... wn=false#2

选择上面这个链接中unix条目下那个“LINUX driver for kernel 3.x and 2.6.x and 2.4.x”、版本为“8.038”的文件下载。下载好文件，解压到你的家目录中，然后在家目录中执行以下命令：

代码： 全选

cd r8168-8.038.00
sudo ./autorun.sh

驱动安装完成，重启系统。你的有线网络就应该正常了。

如想确认新的驱动的情况，执行

代码： 全选

sudo lshw -C network |grep r8168

在输出中如果看到“driver=r8168 driverversion=8.038.00-NAPI”，那么就说明系统已经使用了正确的驱动了。

按照这个回复安装好驱动后表示还是不能有线联网。。。另外执行
代码:
uname -a
lspci
sudo lshw -C network
ifconfig
ping 192.168.1.1 -c 4
tail /var/log/syslog -n 20

这些log说明你现在的8168的网卡驱动应该已经是正确的了，但为什么你的eth0要用119.78.236.172这个地址？--在255.255.255.0这个掩码下，该地址和192.168.1.1不在同一个网段，又没有其他网关可以连接，当然是无法ping通的。请详细描述你的上网环境/方式，如果是在家里最好dhcp从路由器自动获得ip，不要手动去设。宽带拨号的设置应该在路由器上进行WAN口的设置，客户端电脑上应该拿到一个192.168.1.100之类的地址。。。
