Anyone had experience pairing Motorola MB8600 modem with Asus AC2900 wifi router? When I am connected directly through the modem, everything is fine. The wifi router though can't get internet connection from the modem, saying "your ISP's DHCP does not function properly". Any ideas? The router setup was done through the wizard: Automatic IP, no password.
Do you have IPv6 enabled?
The solution to the problem was to clone the MAC address. It was just a two-click fix. Problem solved.
actually there is/should another way unplug everything then plug modem in wait for it to finish then turn router on
