我有一台 Eee PC 904D，我用它来开发，因为它又小又小，但我也有一台 PC。但是在我的 Eee PC 上，我安装了 Ubuntu Intrepid Ibex 和 Netbook Remix（非常简单），当我想使用以太网电缆上网时，我连接它并尝试连接，但在尝试连接大约 10 秒钟后，它失败了，并且图标发生了变化，就像我没有连接任何电缆一样，但是电缆已连接，当我尝试使用此电缆时，其他计算机可以正常连接，如果需要，这里是 /etc/dhcp3/dhclient.conf 文件的内容：
# Configuration file for /sbin/dhclient, which is included in Debian's
# dhcp3-client package.
#
# This is a sample configuration file for dhclient. See dhclient.conf's
# man page for more information about the syntax of this file
# and a more comprehensive list of the parameters understood by
# dhclient.
#
# Normally, if the DHCP server provides reasonable information and does
# not leave anything out (like the domain name, for example), then
# few changes must be made to this file, if any.
#

答案1
您尝试过网络管理器吗？网络管理器不使用 dhclient.conf。您可以在 /etc/NetworkManager 下找到其配置，但最好使用配置对话框来完成。
答案2
它有 IP 地址吗？在控制台中输入“ifconfig”并查找 eth0 的地址。如果它有 IP 地址，请尝试通过其 IP ping 另一台机器。
