Wi Fi compatibility - Two webs in the same home

Hi Friends,

I need help, please.

I had to put here in my ne home a TP-LINK DECO E4 to extend the wi fi. I have a router with a limited range, once it didnt reach where the Form 2 is right now.

So I created another web, that reaches all the house, but when I open PreForm, it says that the printer is offline.

I think the problem is the IP address, but I don’t have enough knowledge to solve it.

Could anyone try to help me please?

Thanks so much!
