Query: Worst dlink product I have used

Have been using this router for the last 2 months or so. I have already returned one unit for replacement, which cost me $15 in shipping under warranty because dlink does not cover me shipping the unit to them (didn't know this!). second unit is still just as unreliable. reception is not any better than my older g router. wireless connection is laggy and slow. lose connection every so often. customer service is horrible (they claimed that these are happening due to my ISP yet I had been using the same ISP w the old router w no problems). so far I am sorry that I have upgraded to n. stay away from this router.
