Why do I want to do it? Actually, I don't. I actually want to find out what devices have been attached to my router (their MAC addresses). However, everyone insisted there's no way to find out that, but IF the device had been renamed then it seems possible to find out, from the internal memory, what the MAC address was if it had been renamed. A long shot, sure, but I was just thinking the process through. My thought was that the information is actually there... even if no one seems to know how to get it.
