D-Link will not patch a critical unauthenticated command-injection vulnerability in its routers.  This vulnerability is serious because it could allow an attacker to remotely take over devices and execute code.  The affected "consumer grade" D-Link routers are not designed to last for longer than a year or two. So it's not surprising, that D-Link has decided to not fix the vulnerabilities.  Business consumers should always take into account the (TCO) "Total Cost of Ownership"  and not just the sticker price when making purchase decisions.
