so i bought this asus RT-AC51U so it can replace my modem/router combo. but i keep getting some errors like " ISP's DHCP did not function properly." but when i used my modem only the internet never drops. so the problem has to be with the router.
i tried different cables but same problems. any of you have ideas to what is causing this problem?
