Hey Folks,
I just received my second defective unit for this "rare" issue. If your DPH-50U suddenly drops a call after some random time (I've not made it past 20 minutes) and you are told by the engineer in this forum and by customer service that you have a "defective unit" don't bother returning it and getting a replacement.
Return it, get your money back and go buy another brand.
These "engineers" seem to be more interested in making excuses than solving problems. I'm no novice to technical problems - did everything they asked - upgraded drivers - multiple workstation installations. Two defective units in a row = poor quality control.
D-Link Customer Support's advice - return the second unit for a third.... no chance, wasted enough of my life on D-Link products.
Good luck,
Peter
