Public bug reported:
I have attached multiple WLANs to my computer. One is build-in (pci) and one is
connected via usb.
The Ubuntu Gnome GUI shows 2 WLANs and for both a different signal strength.
When however I disable one of the WLANs via the "Turn Off" option, it is
expected that only this WLAN is deactivated, however both WLANs get disabled at
the same time. When enabling one of them afterwards, both get enabled again.
There does not seem to be a way to disable one of them alone.
