Weird... is this happening for every LTE modem out there? We could have a new property in MMBroadbandModem specifying that +CSQ is always preferred over +CIND for signal quality updates (talking about git master here), so that plugins can set it when that happens.
Or, if the issue is really more generic and happens with most LTE modems out there, we could force using +CSQ when in LTE. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-applet in Ubuntu. https://bugs.launchpad.net/bugs/1060831 Title: Sierra/ZTE LTE modem gives no signal quality in LTE mode (only in 3G/2G mode) Status in “modemmanager” package in Ubuntu: Triaged Status in “network-manager-applet” package in Ubuntu: Invalid Bug description: In LTE mode, the sierra modem (MC7710) gives no indication of signal quality in nm-applet.

The signal is good (I measure download rate of 37 mbits/s), and in 3G/2G mode I get the correct signal quality indication. Could it be that MM should not use +CIND but instead +CSQ?
