Your orginal post is actaully on our global community located here:  Its possible when you first went to our community you were directed there instead of the US specific one.  

Well, radio waves actually are affected by the ionzation in the atmosphere so can react differently at night rather than at day.  This usually equates to be range but aslo typically only applies to outdoor communications.  What is more likely is that it is happening during the day as well and you just aren't seeing it.  We would first recommend reloacting this unit a bit closer to the router and then observe if the concern is still happeing.
