Absolutely not roadkill. What ever you do, don't go tinkering with your innards!
However, as I mentioned above, you should try to do this "if possible". I say it like that because not all makes and models may let you do this. I have no experience with the D-Link devices.
I know it's certainly possible with Cisco gear.
But if you only follow the first 4 steps, you'll be infinitely more secure that if you simply use the AP "out of the box".
