使用网络管理器升级到12.10后无法连接huawei e173
自从12.04升级到12.10后，我无法使用移动宽带调制解调器华为e173连接到互联网。 它工作得很早没有问题，现在它似乎被正确识别（至少它的连接出现在网络管理器小程序中），并且在手动选择连接后，它开始连接程序。 大约20秒后，它返回到断开状态。
浏览互联网后，我发现运行网络管理器：
NM_PPP_DEBUG=1 /usr/sbin/NetworkManager --no-daemon 插入调制解调器后我得到：
NetworkManager[507]: (ttyUSB2): failed to look up interface index NetworkManager[507]: (ttyUSB2): new GSM/UMTS device (driver: 'option1' ifindex: 0) NetworkManager[507]: (ttyUSB2): exported as /org/freedesktop/NetworkManager/Devices/2 NetworkManager[507]: (ttyUSB2): now managed NetworkManager[507]: (ttyUSB2): device state change: unmanaged -> unavailable (reason 'managed') [10 20 2] NetworkManager[507]: (ttyUSB2): deactivating device (reason 'managed') [2] NetworkManager[507]: (ttyUSB2): device state change: unavailable -> disconnected (reason 'none') [20 30 0]
“未能查找界面索引”似乎是可疑的。
开始连接后：

持续约20秒。
我试图降级网络管理器但由于许多依赖项而失败。
任何人都可以指出我的解决方案或告诉我该怎么做才能进一步调查问题？
这是因为Ubuntu 12.10附带的ModemManager 0.6.0.0中的错误（或错误）。 您可以删除此调制解调器管理器版本并降级到0.5.2。
检查调制解调器管理器版本： dpkg -s modemmanager
下载0.5.2版本： 链接64 — i386
这是一个修复bug的链接： https ： //bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/1057186
如果您尝试所有选项在Ubuntu 12.10上安装华为E176并且没有得到。 有关于此博客的解释，需要安装其他想法，如果您需要支持，请联系博客。 该文是葡萄牙语，如果谷歌翻译没有帮助你，博客的创建者可以尝试： https ： //www.blogger.com/blogger.g？bloglog = 5276226360297889948#editor / target = post; posttID = 20097788084129220816 ; onPublishedMenu = allposts; onClosedMenu = allposts; postNum = 1; SRC = postname
