AT&T fiber modem doesn't like my Asus router (alien.top)

Hopefully y'all can help me out. I just got ATT fiber and I want to hook my Asus RT-AC88U router to it but it doesn't want to work. If I connect to the att wifi I have Internet but if I connect to my Asus router all I get is "server not found" and there is a red light on my Asus router where it should be white when the Internet is connected.

Normally with other ISP's in the past I just hook it up and go even if the ISP modem is also a router it just plug and play and works. So I can't figure out why it's not working. Does att do some bull crap so you can't use your own 3rd party router instead of their trash?

There aren't any restrictions on what downstream device you can use.

Could be an address conflict. Check the lan address range on your Asus router. If it's using 192.168.1.x then it's conflicting with the AT&T gateway. Change to .3.x or .99.x or something else from 2-254.
