Read connection logs mycloud ex2

Hi there,

I want to check if my MyCloud Ex2 Ultra is losing network connection, for a brief moment. Can somebody help me to find the right log and explain me how to read it?

I believe that my wifi extender might lose connection for about 10-30 seconds multiple times a day. The mycloud is connected via a networkcable to the wifi extender. The extender I had to reset so i lost all my logs there. I managed to create and download the logs of mycloud, but I have no idea where to look. I hope someone can help me out!
