No thanks, ***** ***** wanted to register my product and do not plan on connecting to the DSL modem until tomorrow. So thanks for the advice that I seen in the set up instructions. Please disregard my enquiry. Adam *******
are you trying to just register your ownership with asus ?
i would try waiting until the router is installed and connected to the internet.
It should register itself automatically or at least they will be able to find the mac address of the router when you send the serial number.
it may be giving you a hard time just because they can't see the router existing when you are registering it.
But it could be some other silly problem as well such as a bad email address etc.
