Known security flaws in this router are documented publicly and will never be fixed. D-Link stopped releasing security updates. Anyone scanning for known vulnerabilities can find your work laptop, your phone, your Ring doorbell, and every other device on this Wi-Fi.
When this router launched, it was a reasonable choice. It’s still functional — the lights still come on, devices still connect. What changed is that D-Link has moved on, and any flaw researchers find from now on stays exploitable forever. The risk is invisible until something goes wrong.
