My Macbook pro doesn't connect to any wi-fi a few hours every day

Hi.

I have bought a Macbook pro 13in 2016 a few days ago. Every day after working with internet for a few hours, it suddenly won't connect to any wi-fi around. I have been trying everything to solve it but I can't. I have restarted my laptop,my router, my wi-fi,using different channels on my router, used other wi-fis like my mobile hotspot,I have deleted and added wi-fi from the list on the network preferences window ,I have added a new location also.

I have seen so many youtube videos and read many posts on the internet.

I also tried the method on which we delete a bunch of files on system configuration folder and it didn't work too.

So please, please give me something new, because I have spent a lot of money on this new laptop and it drives me crazy that I have to deal with this problem every day and not be able to solve it.
