网卡应该是识别了，而且已经拨号成功了，为什么会ping不通呢？ 有没有人做过这个，给指点下
[解决办法]
帮顶。。。。
[解决办法]
帮顶，我现在也在做这方面的东西，还没有成功
[解决办法]
哦，3G啊，不错......
[解决办法]
网关没设置对，把 ppp0 设置成默认网关。
$NET_DEVICE＝ppp0
ORT="`route | grep default | awk '{printf $8}'`"
route delete default dev $ORT
route add default dev $NET_DEVICE
PS:
把你的拨号脚本贴给我看看。。 我的 3G 拨号还有问题呢。。 哎。
[解决办法]
看看
回复内容太短了！
[解决办法]
dm6446 做的手机？我们用来做视频处理
[解决办法]
最近我们的RD也在用华为的3G卡（E180）做LINUX/Android下的开发，不过总是跟ISP的沟通有问题，参见下面的log，猜想可能的原因是1》CHAP-SECRET用的不对，我们用的是bogus；2》PPP opinion。看到你的3G卡接入没有问题，能否帮忙释疑？非常感谢。
