Router assigning wrong LAN IP to new devices (alien.top)

So my household has 3 routers, 2 Asus RX-AX86U’s and 1 Actiontec T3200M (ISP Router).

When I first got my Asus AX86U everything was running perfectly fine! But once I got my second AX86U for the living room (same room the ISP router is in) I’ve noticed that any new device that connects to my network is being assigned a LAN IP from our ISP router rather than my network.

My LAN IP’s typically go 192.168.50.xxx while our ISP router goes 192.168.1.xxx

If anyone has an idea I would greatly appreciate it!!

If I could unplug & ditch the ISP router I would however, it is required for actual television + the family uses it.

Edit; Manually assigning the IP via device MAC seems to work but extremely obnoxious to do every device.

It sounds like you have multiple dhcp servers running, This is a non-no and while causes issues.

Ay I just wanna say thank you for the comment, I’ve spent the last 2 nights struggling to get this to work.

The best I’ve come up with so far is manually changing my routers IP to 192.168.1.1 albeit this has caused the routers to conflict killing all internet access (yet again). I honestly can’t figure this out and I’m so stressed over this.
