Bug 314751

Which Plasma NM version do you use and what is your modem's model and manufecturer? Keep in mind that some modems do not report signal strength (only the numbers of bars for that signal strengh) and as so there will be no percentage coming from ModemManager.

"KDE - Live free!
Platform Version 4.9.4 "

Version of the modem: Ducati Honda MDC 502 HS

With different graphical environment (xfce) also indicates the
percentage of the signal.

Thank you, good job

I meant the Plasma NM version, not KDE SC's. You can see Plasma NM's version string in "Manage Connections" -> "Other".

I was not able to find if that modem has problems to report signal strengh with ModemManager. What does the command below return?

dbus-send --system --print-reply --dest=org.freedesktop.ModemManager \
/org/freedesktop/ModemManager/Modems/0 \
org.freedesktop.ModemManager.Modem.Gsm.Network.GetSignalQuality
 
If /org/freedesktop/ModemManager/Modems/0 is not your modem use the command below to figure that out:

dbus-send --system --print-reply --dest=org.freedesktop.ModemManager \
/org/freedesktop/ModemManager org.freedesktop.ModemManager.EnumerateDevices

I am not sure if xfce uses ModemManager to handle 3G modems.

Thanks.

You should use the command below (all in one line) to see if ModemManager reports signal quality:

dbus-send --system --print-reply --dest=org.freedesktop.ModemManager \
/org/freedesktop/ModemManager/Modems/2 \
org.freedesktop.ModemManager.Modem.Gsm.Network.GetSignalQuality

Ok, so it should work in Plasma NM. What is the Plasma NM version you use? You can see the version string in "Manage Connections" -> "Other".

version 0.9.0.5 (nm 09 20120930)

I have just pushed a commit [1] that problem fixes the download speed problem. I am investigating why signal quality is not working.

Thank you, good job

Is the signal quality problem still happening with Plasma NM 0.9.0.8?

*** Bug 319257 has been marked as a duplicate of this bug. ***

If you can provide the information requested in comment #1, please add it.

Hello,
I'm still trying to get the signalstrength of my 3g device and making it visible in the applet. At the moment it's just an "empty" space in the tray. I tried 

dbus-send --system --print-reply --dest=org.freedesktop.ModemManager \
> /org/freedesktop/ModemManager/Modems/2 \
> org.freedesktop.ModemManager.Modem.Gsm.Network.GetSignalQuality

Error org.freedesktop.DBus.Error.UnknownMethod: Method "GetSignalQuality" with signature "" on interface "org.freedesktop.ModemManager.Modem.Gsm.Network" doesn't exist

dbus-send --system --print-reply --dest=org.freedesktop.ModemManager \ /org/freedesktop/ModemManager org.freedesktop.ModemManager.EnumerateDevices

process 3964: arguments to dbus_message_new_method_call() were incorrect, assertion "_dbus_check_is_valid_path (path)" failed in file ../../dbus/dbus-message.c line 1266.
This is normally a bug in some application using the D-Bus library.
process 3964: arguments to dbus_message_set_auto_start() were incorrect, assertion "message != NULL" failed in file ../../dbus/dbus-message.c line 2951.
This is normally a bug in some application using the D-Bus library.
Couldn't allocate D-Bus message

I'm working on Ubuntu 13.04 Kde 4.11 NM-Applet 0.9.0.9 with 0bdb:1911 Ericsson Business Mobile Networks BV

Thank you

i should mention, that it sometimes showed signalstrength when desktop effects where off, but not anymore
