Has a power off for 1 minute then back ON with the ISP modem and router been performed?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.

Thank you for your response.

 

  1. Yes I have tried powering off the cable modem and router for upwards of 30 minutes.
  2. I have attempted to factory reset both the cable modem and router.
  3. The NIGHTHAWK DOES NOT obtain a WAN DHCP IP address when connected to the ARRIS TM822 (CABLE MODEM).
  4. The TP-LINK (DD-WRT) DOES obtain a WAN DHCP IP address from the ARRIS TM822 (CABLE MODEM).
  5. My PC (ETHERNET) DOES obtain a WAN DHCP IP address from the ARRIS TM822 (CABLE MODEM).
  6. The NIGHTHAWK DOES obtain a WAN DHCP IP address when connected to the TP-LINK.

  Internet Provider support did mention that they had issues with Netgear routers.   Not sure if that means they have a permanent ban on them somehow but replacing the MAC on the WAN side should resolve that issue.
