Your Huawei E173s-1 modem isn't listed upstream https://live.gnome.org/NetworkManager/MobileBroadband
as supported. If you want NetworkManager to support this modem it's best to file a report upstream. https://bugzilla.gnome.org/browse.cgi?product=NetworkManager It nice to hear that you can configure this modem using Sakis3G. http://www.sakis3g.org/ However, I don't see a package for this in either Debian or Ubuntu, so that software isn't supported. My guess is that there is a problem with routing. ** Summary changed: - Network manager does not fully recognize Broadband internet through sakis3G + Networking not fully functional after connecting to broadband internet using the sakis3G utility ** Changed in: network-manager (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1058547 Title: Networking not fully functional after connecting to broadband internet using the sakis3G utility To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1058547/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
