Ok, when you bought it was it from Dlink or some retailer? The refund is not from Dlink but that retailer.
In closing, we see this complaint about many routers. Can you try it per our forum sticky and reveal if P2P use is part of the problem?
Stay away from this product.
What a nightmare product. Not only is it as useless as **** on a boar, but they won't refund your purchase!
I spent weeks with the D-Link tech folks, who are as frustrated as their customers. They can't get a firmware made that will keep the unit online and conflict-free. What ends up happening, as a customer, you end up as their beta-tester... and you get to pay for the privilege!
If you are thinking of buying this junk-bin item, do your homework! Read up on all the other users pulling their hair out trying to get their units working.
You have been warned!
