用交叉网线直连可以, 用普通网线接入局域网就不行? 现象如下? 到底是什么地方出了问题呢?
--------------------------------------------------------------------------------------------------------------------------------
怎么配置, 网络都不通, 网卡上的灯是亮的,但是只有一个灯亮, 下面是我的配置, 请大家帮我看看呢? 是不是网卡物理上有问题?
网络环境: 办公室DHCP环境,
本地配置: 设置静态IP

PC机ping开发板 不通
PC机上Ethereal抓包可得: 90 向 91 发出 ping request, 但是没有任何91回来的包.
开发板ping PC机 不通, 开发板显示信息:WATCHDOG: eth0: transmit timed out
PC机上通过Ethereal抓包可得:
