This i do understand, but I'm having difficulty to grasp why the info of the "occupant" to the IP in the list of devices connected on my router differs from the info given under Settings --> Hub Details.
Same IP listed in both places, but different MAC's.
Could it be an idea for the future to have both MAC's more clearly stated on the sticker on the bottom of the hub, and also in Hub Details? I.e. Ethernet: this, WiFI: that. Guess this could help out confused, middle aged men like me. 
Anyways, thanks all for your support, I will let it rest for now as everything works and it's really only a minor nuisance.
