请教高手，本地网卡和无线网卡均不能ping通网关
发布时间:2008-03-10 11:09:59来源:红联作者:changlee
现在还处于对linux摸索阶段，刚装上fedora 8 一切顺利，本地网卡和无线网卡驱动均正常安装，在图形界面中配上IP地址并正常激活，但是都无法ping通网关，后来把防火墙禁用了，还是，显示只有发包，没有收包，而这个IP在windows下面能正常上网。在命令模式下面也运行了ifconfig up，ifconfig显示有正确IP。水平有限，请高手们指点一二，先谢谢了。

iwconfig 是设置无线网络的～

已经能够正常上网了，原因是需要用iwconfig设置参数，以前不能上还有个原因可能是因为设置的信道不正确。感谢楼上提供帮助的人们。

你的情况是:一张网卡上绑了两个IP！
eth1:0 这个IP不知道是怎么被你获得的，是否是手动设定的！
理论上应该只有在 eth1 正常连接的前提下，eth1:0才能获取到IP。
建议将eth1:0 删除！如果路由器开通DHCP功能的话，先关闭无线，让本地网卡获取IP，测试是否使用！
关闭有线连接，尝试无线是否能连接，测试是否能使用！

详细的上网方式是通过局域网网关连上internet。现在需要解决的问题就是ping通网关。网关为无线的AP，可通过网线和无线连接。现在本地网卡已能和ap连接，但是无线仍然不能。本地网卡为eth0，无线为eth1

详细的上网方式是什么..以及ifconfig的内容粘上来看看...
