I rec'd yesterday (sep 15) my DAP1522, and I've got a poor connection (14Mbps at 33% in Bridge-Mode).
Today I make 2 hole's on the back-side and glued 2 arial-plugs, and they must dry in several hours from now.
Before that, I did a second test (the antenna are in a bad posititon, because they were not fixed yet with glue),
but my singal strength was increasing already, now about 50% and the speed between 40-50Mbps.
Both test's are on the same location!
I wonder why D-Link didn't deliver the DAP1522 with ext. antenna's
