Router GENEXIS-Access possible without connecting to the network?

Question

WiFi

Good afternoon.
I live in Europe, until I earned my own housing, I have to rent. Well, I'm tormented by vague doubts that I was restricted access. Because yesterday I watched a movie on TV, and in the middle of watching the Internet disappears (I wrote it off for the weather)
Today I try to connect, whether on TV or on a phone with a laptop, it says it’s not possible to connect to the network.
Knowing the WPS PIN SSID WPA KEY, is it possible to get into the router settings?
