I've been messing around with my settings and been searching for the cause of why my router stops responding, accepting input and failing to connect.  I've discovered that if I don't clone my pc's mac address everything that I try works fine.  The moment that I clone my pc's mac it is unable to establish a connection to my modem and will not accept any further input.  Will someone else try this with their router and see if they get the same result.  I'm hoping that someone from dlink will respond.  For the moment I'm leaving my mac alone using the default address since it works.

If you change the WAN side MAC address (e.g. cloning it) you'll have to power cycle the modem so your ISP drops the currently registered MAC address for a new one.

I've been running it cloned to my pc which was used to establish the service connected directly to the modem.  For whatever reason the router will now act up if I try to clone the mac address that has worked since the beginning.  Maybe I'll try cloning the address first then make other changes later.

I have this same problem, but didn't think much of it. What's the purpose of doing this though? I just leave mine all 0's and it works. If I clone it, it won't work. What does clone'ing it do exactly?

When you connect the modem to the PC, the ISP see's the MAC address of the NIC in the PC. We added the cloning feature as a way to "trick" the ISP in to thinking that the same PC was still connected. This feature isn't really needed any longer, as MOST ISP's allow the use of routers. However the cloning feature can be useful if the modem is already bound to a PC's MAC and power-cycling is not an option, like with Time Warner's VoIP where the modem has a battery in it.
