GL-A1300 a little setup question

Hello guys and thanks in advance to anyone who will help me.
I got GL-A1300 and right now I’m using the it in the following setup:

smartphone->tethering->A1300->ethernet->smart tv.

Now I have the need to use Chromecast so I wont be able to connect it thru ethernet but i need wifi, so my question is… to make it work, do i have to change anything in the router settings (192.168.1.1), like some mode or something, or i can just use Chromecast, find the router network there, connect to it, and thats pretty much it?

Sorry for asking but i dont have the router here at home so i cant try it myself.

Thanks!!

I never used chromcast. Let’s connect it first and if any issues arise, come back and we can assist you.
