After installation of Ubuntu 12.04 (from scratch; no upgrade) I configured Mobile Broadband.
Result: Wired and Wireless networks are listed, but no Mobile Broadband. sakis3g works without problems. I have repeated some of my previous steps to investigate this problem. It seems somthing reconfigured the system - maybe set vendor id ? Now the modem is recognized and entries in section Mobile Broadband is listed. The change is persistent = survis reboot => Now the modem is detected and I can use nm to connect => problem solved -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/799351 Title: NM does not connect mobile broadband; sakis3g and wvdial can connect -- Huawei E156G Status in “network-manager” package in Ubuntu: Expired Bug description: Problem: On my system Network-Manager (version 0.8) cannot establish connection with my Mobile-Broadband modem. sakis3g (version 0.2.0e; http://www.sakis3g.org/)and wvdial are able to do it. Windows version of mwconn (ixconn; version 0.4; http://www.mwconn.com) connects without problems. I have : * uname -a Linux martin-laptop 2.6.32-32-generic #62-Ubuntu SMP Wed Apr 20 21:54:21 UTC 2011 i686 GNU/Linux with latest updates. * GSM-Modem: Huawei E156G (now unlocked, in the past Three Austria) * SIM Card from Yess (www.yess.at) In the past I used the modem with a three sim card without problems. The new sim card was working with the delivered modem (Huawei E170) after I have deleted all Mobile Broadband connections and created a new one. I dont know what modem-manager and network-manager are doing in background, but I have expected that any sim card is working with an unlocked supported modem. Below my gathered information. Maybe somebody finds something. ------------------------------------------------------------------------------- After reboot with connected modem: Try to connect with network manager (Click on entry below Mobile Broadband) cat /var/log/syslog: Jun 18 20:41:31 martin-laptop NetworkManager: <info> Activation (ttyUSB0) starting connection 'Yesss Default' Jun 18 20:41:31 martin-laptop NetworkManager: <info> (ttyUSB0): device state change: 3 -> 4 (reason 0) Jun 18 20:41:31 martin-laptop NetworkManager: <info> Activation (ttyUSB0) Stage 1 of 5 (Device Prepare) scheduled...
