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.

Thank you for this, unfortunately I’ve been at this the last 2 nights and it’s been nothing but stressful for me. I honestly don’t know why this isn’t working for me, my ISP router calls it “Bridge Port1” and my router calls it Bonding/Link-Aggregation and neither of them are willing to talk/work with each other, always fighting to assign LAN IP’s..

    What kind of internet do you have? Fiber, DSL, or cable? I'm also wondering how your TV is set up as well. Is it hooked through a coaxial cable right into the modem? A picture of the modem might help.

    Cable tv shouldn't require a modem under most circumstances. Unless you have fiber optic TV, which then converts digital signal of fiber back to analog signal through coaxial cable, which then hooks into your TV?

    Also, here's some copy paste from forums I found on how to out your isp router into bridge mode, in case you truly need it for TV:

    Select ADVANCED SETUP Select PROCEED at advanced user challenge screen Select WAN IP ADDRESSING under the IP ADDRESS section on the left-hand menu. In SECTION 2, Select RFC 1483 Transparent Bridging Select Apply to save any changes at bottom of screen. The "Internet" light on the front of the modem should go solid RED. This indicates the modem is in Bridge mode.
