RT-N66U and DDNS Quit Working?

[mike7143]

I'm about to dust off and drag out my old D-Link router that the Asus replaced; it should still be configured exactly how I left it when I unplugged it a couple years ago. Never had DDNS issues with it. I suppose if it works then maybe something's wrong with my N66U or perhaps firmware issues. But if it also doesn't work, then I'm lost, and all I can think of is something my ISP is doing...

Are you still having these issues after following the steps I've outlined in post 16?

(And tried explaining the reasons why you may be having these issues with your router).
