I upgraded my N66U to the latest Asuswrt version 3.0.0.4.374.5517 as well as to the latest version of Merlin's firmware and I noticed that when I try to clone a MAC address it will not attempt to obtain a WAN IP address after the first DHCP failure observed in the logs. The issue persists regardless of whether the DHCP query frequency is set to aggressive or normal mode but the he issue goes away when I remove the cloned MAC addresses. Everything was fine until the last couple of firmware versions I thought maybe the issue was just with Asus's build but I also had the same issue with Merlin's latest build. I also thought it was an issue with Charter but I tried using a different router(Dlink) and I was able to clone addresses no problem. Anyone else having this issue or have any solutions besides rolling back the firmware?
