Description of problem:
The new networkmanager plasma addon warns the user when the signal get low, but the way it is implemented makes it continuously spam the user with notifications.

extract of freenode/#fedora-kde :
05:34 < rom1dep> rdieter_work: but as this "low signal" implementation is buggy, don't you thing we have better to stay without ?
05:34 < rdieter_work> how is it buggy?
[...]
05:37 < rom1dep> rdieter_work: somewhere at school I must use a low-signal network, well this works fine, but because I'm not moving the signal stays low for hours and knetworkmanager doesn't stop automatically spamming me :)
05:38 < rdieter_work> ok, it's a relatively new feature, so I'd bet it's done naively.
05:39 < rom1dep> this kind of messages must follow some hysteresis law : the "warning : low signal !" message shouldn't pop again if we didn't got a "powered" signal btw :)
05:39 < rdieter_work> imo, it should notify *once*, and not do so again until at least one cycle where the strength gets strong and goes low again
05:39 < rom1dep> rdieter_work: ;) seems we agree on this !
05:40 < rdieter_work> I'll contact upstream about it, and test it a bit myself in the meantime... if we can't get it to bahave, 
                      I'll see about disabling that notification by default
05:40 < rdieter_work> bad/noisy notification is worse than none here, imo.
