I am on a network on which I have my old router's mac address registered so I can access the internet through this network (it's filtered by mac address).
I've recently replaced the old router and am running DD-WRT on my new router. On this page of the DD-WRT wiki it says that the "mac adress clone" option should enable you to easily replace a router in this kind of a setup. Just clone your old mac address and you're done.
However, I've tried this and it doesn't work for me. As soon as I connect the new router (with the cloned mac address), I'm rerouted to a captive portal and cannot access the internet. I can also see that other computers on the network are connecting to my router (I don't know if that's normal).
Does anyone know why this doesn't work as advertised? Is the "mac address clone" not changing the mac address as it should, or are there any other options I have to configure as well? (I know this is a very general question, but I'm just not very sure where to begin, or what information to provide)
