ichbinbose's first suggestion points out a detail you missed. When something says you have no internet connection, that's not one situation. Your player's wifi receiver might have died. Your router's wifi might have died. Connecting with an ethernet cable would sidestep those two problems.
Your internet might be inoperative. Checking if other devices on your router can get internet will determine if that's the case.
Did you try internet setup, in case the player somehow let go of the wifi connection?
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
