Your modem has already registered itself with the MAC address of your computer, so it doesn't recognize the MAC of your router. In cases like this you have two options:

1. Configure your router to clone the MAC of your computer
2. Connect the router to your modem and do a soft reset so the modem registers itself with the MAC of your router.

Clone MAC - Go to your routers Admin web interface and on the main page you should see the "Router MAC Address" section at the bottom. Select "Use Computer MAC Address" and click "Apply" and your router should reboot and you'll be back in business.


Soft Reset - Plug the modem into the router via the ethernet cable then do a soft reset.

To do a soft reset, do the following:

1. pull the power cord from the modem
2. count to 5
3. hold down the Reset EMR button on the modem
4. plug back in the power
5. count to 30 while holding the Reset EMR button (the modem should be blinking a lot)
6. release the Reset EMR button and see what happens.
