Buying this Router was definitly a mistake for me.
In addition to the UI issue here : http://forums.dlink.com/index.php?topic=61931.0
I'm also suffering from very frequent and regular disconnections.
No Internet disconnections, my modem is working well, but WiFi signal disconnections, see below (DAP1360 in green)

DAP-1360
HW F1 - SW 6.05
Region : MEA
Usage : Access Point
Already reset/reimage the router, and obviously I'm just next to it.
