请教ADSL安装问题

我装了pppd和pppoe的拨号.拨号时ADSL MODEM也在闪,但比WINDOWS慢.然后老是提示TIMEOUT.看日志说是验证失败.请问这是为什么?网卡IP,掩码,网关是随便设还是不能设?拨号失败和ADSL MODEM型号有关吗?是不是不同的MODEM有不同的拨号程序?我的MODEM是Efficient公司的SpeedStream ADSL MODEM那位用过请告知.万分感谢!      
I use pppoe as well.
It's terrific!!!

There is a trick when you configure it.
That is,
You shall input your user name (for example,vip),and dont use your ISP's name(ShanghaiOnline for instance).

:>      
那个当然都填了.还是不行啊.USER,PASSWORD,DNS,所用网卡eth0等要填的都填了.还是不行.WHY?!
