AITA for shutting off my WiFi at night

Hello yall, hopefully this post is not too long as I don’t want to take up a lot of your time.

So let’s begin from the beginning, I moved into my new apartment in July of last year and no one lived below me for a couple of months. After a couple months a guy moved in. The first thing I have experienced from him was blasting his music so loudly that it sounded like it was coming from my apartment as well as vibrating my floors and walls. I have never met him before this and after that I asked him to just try to keep quiet after 11 PM at that is around the time I go to bed. Very frequently he does not shut it off after 11 and I get woken up at 3 AM to it. There was even a time where I had to miss four hours of my scheduled hours at work because he played it until 4 in the morning and I couldn’t sleep and had to get up at 5:30 for work to work an 12 hour shift. I have had minimal contact with him for the occasional neighbor stuff like “ can you grab my package off the porch so it doesn’t get stolen” etc. well a couple days ago he asked me to use my WiFi for a couple of days until he can pay his own WiFi. I allow him to use it for free of charge because I know we are all struggling in this economy. However, I have this deep fear of a fire happening at my house, so I unplug everything at night that is not being used. WiFi being one of them as I do not need it when I am sleeping. I woke up this morning to messages from the neighbor that are so disrespectful about the WiFi not being on. AITA?

Update: Thank you all for your replies. I have decided to change my WiFi password and not allow him to use it. A little more background though on a couple of things though. So the apartment I live in is more of a duplex so there is only me upstairs and the downstairs neighbor who live here. As for the noise complaint I have called the police and the only thing that happens is he will turn the music off when they come but the next day it is back to being on. I have learned there is some battles worth fighting and this one isn’t worth my battle as it is never going to change no matter who I go to about it. As for the whole letting him use the Wifi thing is that I don’t want to cause issues while I’m living here and I want to keep the peace as to not make things worse then they are. However at this point I have done everything to keep the peace and none of it does not seem to be working so I might as well just be an “a-hole”.

Update #2: The WiFi password has been changed and WiFi name has been changed. I don’t think he appreciated that because he blew my phone up while I was in class then just texted me Bet when I did not answer. I’m pretty sure he has his own WiFi now as his music is once again blaring. I’m also pretty sure he is planning something because I was just outside with my dog and girlfriend and he was recording us through the window on his phone. Im not really sure where to go from here as I cannot move just yet so I think I am gonna talk to some people to see what I can do from this point forward.
