Bug 340306

Have you tried to deactivate your ethernet connection? I think that the reason why it doesn't show any download/upload is that everything is downloaded/uploaded via your ethernet connection.

Screenshot of Plasma-NM. Only Mobile Broadband connected

I've attached a screenshot of only the mobile broadband connected. I checked the possibilities before posting

The LAN is connected to a local storage device that's not connected to the internet, so the gateway is the 3G modem. I've also disconnected the VPN, so in the screenshot, internet activity is going directly through the provider's service. The problem is still there

I'm just doing an update of plasma-nm and libnm-qt for Fedora with some fixes for modem connections so if you could try it and report whether it solves your problem or not that would be great.

If you don't want to wait for the update (which takes a while), you can download new builds directly from koji, just wait until build is finished for your architecture.

The problem seems to be resolved. I've noticed that kde-plasma-nm-mobile doesn't come installed with the rest of plasma-nm, it wasn't on my system and when attempting to install the updates from koji I was prompted to install it (not update it)

When installing the current stable package from the update repo (with your test builds from koji) speeds disappear. But when installing the test package (along with the other koji packages) things work as they should

So I can't confirm if those particular RPMs fixed the problem, or whether it was plasma-nm-mobile (because I can't get a clear explanation of what nm-mobile is supposed to do)

It was not caused by missing kde-plasma-nm-mobile, because this subpackage is just for dependencies and it actually doesn't install anything. Problem was in IpInterfaceName property in modem device, which was not updated properly and thus we didn't know proper path to get current download/upload.

Watch for IpInterface change, otherwise it won't get updated
This is necessary for ModemDevices as IpInterface is used for monitoring
of current download/upload

Add workaround to properly update IpInterface

A minor problem arose. The original problem is resolved, but now sometimes after multiple connects/disconnects the speeds disappear altogether. The problem happens more often if the only connection is 3G, less often/maybe never when LAN is connected

Screenshot of speeds disappearing

I was able to reproduce your issue, but the speed appeared later. I guess it's some issue in Plasma dataengine which we use for that and since you just need to wait for a while to get the speed I don't consider this as an issue.
