Can I use my old ASUS ROG Rapture WiFi 6 Wireless Gaming Router as a Modem or ONT for my R3

[ErikNox]

Sorry if this is a dumb question but I was wondering if I can use my old ASUS Rapture as a ONT or “modem” for my R3 I have local fiber internet and my fiber box that is on the wall does not connect to my WAN like it doesn’t work so I was just wondering if my old ASUS would work so I don’t have to fork up another 100 plus. Thanks

Yup, just place the IP of the R3 into your Asus DMZ

 

So long as you don't have the same IP space over lap, you should be good

What do you mean the box on the wall doesn't connect to your WAN exactly?

[ErikNox]

I have like a Ethernet port that connects to our fiber on the wall it’s like a little box and in the past I would connect a router there and it would work but with the R3 I tried to connect it to the WAN port on the R3 and I wouldn’t get internet.

Do you know if your require PPPoE/VLAN in order to get a connection?

[ErikNox]

I’m not sure. Do I try both and if so how would I try both?

[Netduma Fraser]

It's not something you could try as would require specific credentials/values, if you don't know then it's likely you don't need it. Are you able to reboot the box on the wall? If so reboot it, wait 2 minutes, reboot the R3, wait 4 minutes then see if you get internet through it

Unfortunately I cannot reboot the box on the wall should I post a picture to show what it is exactly? 

[ErikNox]

It’s the one on the right. That’s what I connect to the WAN on the R3 and it wouldn’t work.

Check the Asus internet settings and try to mirror those on the R3 to see if you can get a connection that way.
