Good evening everyone.

I have recently purchased a WIFI range extender of the informed model, TL-WA850RE(BR) with the Brazilian Firmware, and it simply won't let my laptop or any other computer connect to the main router's WIFI network, even when being within range of the main router's network. Even my family's phones can't connect to main router net when the WIFI Extender is working. Can anyone shed some light on my issues here? I have no idea what I'm dealing with. The only idea I can come up with is that the WIFI Extender uses the same IP Range as the main Router, and it won't let me change it, so I'm thinking this might be causing conflict issues with both networks using the same IP Range. Plus, I already have two networked printers connect via WIFI to main router, as well as a USB dongle that monitors my solar pannels and I don't wanna have to configure them to connect to the Extender, cause I'm lazy and dealing with printers is a PITA.
