Working on it now I have also problems with connecting via mobile broadband, but I am not sure if it is the same. I described the problem in KDE-Forum and was advised to file a bug. If you think the problem is not related, I can file an extra bug report. Problem description with logs is here: http://forum.kde.org/problems-with-networkmanager-applet-and-mobile-broadband-t-59914.html#pid77702 Having issues with "Mobile Broadband" aswell. No problem with wvdial.
Versions:
pppd 2.4.5
NetworkManager 0.7.0.r4359
NetworkManager-kde4 0.7.svn970012
----------
The config file created by the NetworkManager applet is strange (baud, mru, mtu, baud, bits).
[connection]

After manually editing the settingsfile for the connection and rebooting (don't know howto force the applet to reload the connection files) it now works for me. I changed the following to: baud=0 mtu=1440 mru=1440 bits=0 Before the following command was executed: nm_ppp_manager_start(): Command line: /usr/sbin/pppd nodetach lock nodefaultroute user dummy /dev/ ttyUSB0 noipdefault noauth refuse-pap refuse-chap refuse-mschap-v2 nobsdcomp crtscts usepeerdns mru 3342391 mtu 3342437 lcp-echo-failure 5 lcp-echo-interval 30 i pparam /org/freedesktop/NetworkManager/PPP/0 plugin /usr/lib64/pppd/2.4.4/nm-pppd-plugin.so Now when working I get: nm_ppp_manager_start(): Command line: /usr/sbin/pppd nodetach lock nodefaultroute user dummy /dev/ ttyUSB0 noipdefault noauth refuse-pap refuse-chap refuse-mschap-v2 nobsdcomp crtscts usepeerdns mru 1440 mtu 1440 lcp-echo-failure 5 lcp-echo-interval 30 ipparam /o rg/freedesktop/NetworkManager/PPP/0 plugin /usr/lib64/pppd/2.4.4/nm-pppd-plugin.so I don't know if the MRU or MTU values are the best, but thats what wvdial uses. Hi all, I have similar problem with my Boardband device. I'm using Sierra AirCard 880E. I had the same strange values for mtu and mru in the configuration files and I changed them according to what Dan suggested (thanks Dan), but as you can see below it didn't help. In my case ppp plugin doesn't even start. Or is it because debug is not turned on, btw: how do I turn debug on ?

The same problem for E180 in KDE 4.3.2 In KDE 4.3.1 all works ok Since works now ... kde trunk... I find it fair to close it as soleved... Thanks all who contributed. Alin |
