Instead, ModemManager uses the following command to preconfigure the authentication settings to use before launching the connection: AT*EIAAUW=2,1,"username","password" The given username and password are given in the current charset encoding configured in the modem, which should be UTF-8 preferably. Now, the problem is that when special characters are required by the operator, e.g. in the username, the connection will not succeeed. E.g. for A1/Austria operator: AT*EIAAUW=2,1,"p...@a1plus.at","ppp" The issue may therefore be that we either don't pass the username/password encoded properly OR that the modem firmware actually has a bug in that command handling. Debug logs with MM 1.x are needed. Also, it would be a good idea to check whether the setting is READ properly after being written, with: AT*EIAAUR=2,1 Note that PPP on the TTY with those same username/password will actually work.

Shows up in network-manager as having a gsm device, but even with the correct settings it wont connect. I did manage to get it working by installing gnome-ppp and manually configuring AT commands the card requires to active the radio and set the APN. I can get connected this way, but it is not as nice as being able to use network-manager. It also required my user to be added to the dialout and dip groups I think. The 5530 card requires these AT commands to activate radio and set the APN and so on: AT+CFUN=1 ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 AT+CGDCONT=1,"IP","VirginBroadband" Obviously replacing the VirginBroadband with the appropriate APN for the connection. I don't know if its worthwhile but maybe if the network-manager tool had the ability to customise AT init strings under and advanced button for mobile broadband or dial-up modems? Also the card also supports GPS which can be enabled with (for example): AT+CFUN=1 AT+E2GPSCTL=1,5,1 AT+E2GPSNPD lsb_release -rd : Description: Ubuntu lucid (development branch) Release: 10.04 timw@timw-laptop:~$ apt-cache policy network-manager network-manager: Installed: 0.8-0ubuntu2 Candidate: 0.8-0ubuntu2 Version table: *** 0.8-0ubuntu2 0 500 http://archive.ubuntu.com/ubuntu/ lucid/main Packages 100 /var/lib/dpkg/status To manage notifications about this bug go to: https://bugs.launchpad.net/modemmanager/+bug/540003/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
