求助！关于toshiba 的portege 3500 联网

[wjlinux]

刚在toshiba的portege 3500 上装上ubuntu 10.04 ,刚装的时候网络指示灯是亮的，自动获取IP的，关机重起后网络指示灯不亮，连不上网。请大家帮忙看下

运行sudo ifconfig 的结果如下
ub@ubuntu:~$ sudo ifconfig

驱动没问题，是不是网线松了？

[wjlinux]

xp下能上网，应该不是网线松了
有点诡异

[euroford]

最后一招，就是看dmesg了

[euroford]

把这个的结果也贴出来吧 sudo ethtool eth0
本子上面，怎么有两个网卡，不理解

[wjlinux]

运行sudo ethtool eth0 提示没有安装ethtool 工具

[euroford]

运行sudo ethtool eth0 提示没有安装ethtool 工具

这是个调试工具，默认不装的

[wjlinux]

现在明白是怎么回事了，要强制将网卡设置在100M全双工模式，ubuntu默认是10M模式，但网卡是intel 100M pro 只支持100M
