无线网卡能收到信号，但是连不上网，提示连接失败...

[xcjzhd]

我自己买了个无线路由器，并且用windows的那个电脑能用无线连上网，但是，用linux（mandriva）的这个能显示出有无线，名称、信号强度都没有问题，就是点连接之后，会提示连接失败...下面是我iwconfig之后出来的~如果您还需要我提供什么我电脑的信息，可以在回复里提出来~~谢谢各位了~~

没人来看吗？

你尝试安装wicd软件试一试吧，因为你用的是mardriva linux关于这个系统的中文论坛得到的帮助可能会少一些。

wicd用了，但是，在“正在校验访问节点的连接”那里失败了...提示，不能连接到无线接入点...

[jiacunqiu]

我也遇到这种情况的，不知怎么解决。请高手指点一下呀，急用呢。

[coleetas]

我好像在升级network manager后也是这样

我也是这样，我也是在偶然间发现用windows可以连上网，但是在ubuntu下就是连不行，但是在靠近无线路由的地方就没有问题。有没有可以解决的方法

[xtz1990]

正因为这个问题导致我的Ubuntu上不了网
