I go to dlink.com, select "support", enter my model number. Three options -chat, phone, and email. Only chat is available, even though this is a weekday during business hours. Clicking on "call" is just a dead link, it does nothing. I clicked on "chat", and that opens another window with the dlink "virtual agent". I enter my question, and it offers canned solutions which don't fit what I need. When I click "no, this did not solve my problem" it just closes and never offers the opportunity to initiate a chat session.
I hate to do it, but working with dlink support is just so painful and fruitless at this point, it's easier to just buy a new router. From a different company of course. Maybe they won't be any better, but I don't see how they can be any less helpful.
