中移动G3无线上网卡 华为ET128 usb_modeswitch -W错误

[灰色橙子]

系统是Fedora10，按照网上http://hi.baidu.com/chenghui2050/blog/i ... e6fd8.htmleverest0.6 安装 HuaWei ET128 3G上网卡，一切都挺好的，就是usb_modeswitch -W时报错。

dmesg结果出来是这样的
cdc_acm 4-2:3.1: ttyACM0: USB ACM device
cdc_acm 4-2:3.3: ttyACM1: USB ACM device
cdc_acm 4-2:3.5: ttyACM2: USB ACM device

教程说只要出现这个就好了，不晓得，用不用理上一步usb_modeswitch -W的错误？？？？

上一步usb_modeswitch -W的错误是：

最后为什么会报Error？控制信息发送失败？？？


最后我ping了一下。只能ping到自己的IP地址，即只能到达local IP address，而remote IP跟primary DNS还有secondry DNS都不可到达。

大家能否顶下？？？
