Your ISP's DHCP is not functioning properly - Motorola MB8600 + ASUS AX6000
I just bought a new Motorola MB8600 modem and activated successfully. I have internet if I connect my PC directly to the modem. But once I connect the modem to the router (Asus AX6000), the router complains "Your ISP's DHCP is not functioning properly".
I saw similar problem like this thread (https://forums.xfinity.com/t5/Your-Home-Network/Your-ISP-s-DHCP-is-not-functioning-properly-ASUS-router/m-p/3331178#M322290). In the thread above, @ComcastChe was able to solve it by sending a provisioning signal to the modem.
Can someone help me? Thanks
