Help AndroidTV Access Point

[derbmann]

Hello,

I got a AndroidTV connected via Lan and i want a Access Point but the router should set the IP from the connected devices because i want to extend the WLan (same SSID & PW). I search for hours now without any result because it isn't normal that a android device got a Lan port
If i just enable the WLan Hotspot then the internet for the connected devices works fine but they are in a different IP Range. That means that i can't see the connected devices from the routers point of view.

Because the terms are really confusing (at least for me) i have made picture (attachment).
The IP from the "Smartphone 1" need to stay the same after the handover (reserved ip on the gateway/router).
I know cheap Access Points can do this but i want use the hardware that i already got.
Is there any App or setting for this?
(AndroidTV box got root access)

thanks,
Best Regards

If the hotspot utility only allows you to set up it's own separate WiFi network and there are no options to use it simply as an extension to your router's WiFi coverage, there's not much you can do. Which isn't out of the ordinary as a 'hotspot' isn't by design meant to be extender to existing WiFi coverage but primarily used to provide WiFi fed from a cellular signal. You need to have your router acting as the sole gateway to your LAN, so it's the only device providing IP addresses.
You mentioned not wanting to buy anything extra but if your existing hotspot software isn't configurable to your stated needs, perhaps you might want to reconsider that point? It's not even a matter where you need to spend a lot for a high-end router, a typical off-the-shelf router will suffice as a basic extender that will allow you a lot more flexibility to set up both routers to work with each other:
