Any good reason?
May be something with DLink servers?
Also got an email:
Time: 2015-10-06 18:13:14 EDT
Device: DCS-5020L (DCS-5020L, mydlink no. XXXXXXX)
Mail Alert: DCS-5020L was disconnected.
My internet connection was stable at that time.
Is there any log on this model to see if its power went down?
