Haven't tried my self since I don't own a D-Link router. 

However another reason to use dd-wrt:

In short, the guy manage to access the router page with abilities to change settings. This by editing the browser’s user agent string to “xmlset_roodkcableoj28840ybtide”

Tried this on a D-Link DIR-655 and it does not work.
