So my story has some little backstory.

I got into computers and technology because of my dad. He was very enthusiastic when I was little and when I grew older and started my apprenticeship as a software developer he was really proud. Note that he never learned anything like that. He just loved computers and games.

Now to the story itself.
I learned more and more, also about networking and came to the conclusion that our slow internet and rare internet problems probably come from stock/weird configurations. But my dads proud probably told him thats a thing he still has to do as the dad. But it annoyed me so much that I booted into kali linux, loaded an exploit to get the web admin passwort and cracked it within a minute. 😎

Finally I was able to configure everything correctly ( channels were spammed from neighbours so I switched to very unused and the disturbions got less ).

TL;DR: Dad didnt want me to configure our router and didnt give me the admin password, so I booted Kali Linux and used an exploit to get it myself 😎😎
