ubuntu8.04联不上联通宽带

[yb0809]

菜鸟请教：以前装的XP和ubuntu8.04双系统，网通宽带都可以上网。新装的联通宽带xp可以上网，ubuntu联不上网：依次输入sudo poff；sudo pppoeconf输入账号密码，一路yes , 再输入ifconfig ppp0 显示“ppp0:获取接口信息时发生错误：Device not found",再输入plog,显示"pppd[7767]:Exit . pppd[8327]:plugin rp-pppoe.so loaded. pppd [8329]: pppd 2.4.4 started by root,uid 0. pppd[8329]: PPP serssion is 13687 pppd[8329]:Using interface ppp0 pppd[8329]: Connect: ppp0 <--> eth0 pppd[8329]: CHAP authentication failed:user client error pppd[8329]: CHAP authentication failed pppd[8329]: Connection terminated. pppd[8329]: Modem hangup ."请教大虾如何设置才能上网。

刚又安装了ubuntu10.04.2-destop-i386，还是这个问题， 联不上网啊？哪位大侠帮帮忙吧！
