<human>: Can you summarize the given text in a few sentences?

I have to give you some context. I live in an apartment which looks like a residence and my landlord owns every appartements in the building. He offers along with the rent, free internet. (He actually pays for an internet box along with some WIFI extenders) So we are a lot connecting to this internet connection.

Today internet was really slow. I know others tenants are use to download films (they told me so) so I assumed it was the case tonight. I decided to try to shutdown for a few second the internet for everyone, to stop their download.

I successfuly accessed the Control administration of the Internet box through the wifi. No hacking, I just tried the default Login and password (I knew how it works as I did an internetship in a internet operator).
From there, I decided to activate the "Mac filter adress". Basically, from what I understood, every devices like phones and laptops have an IP adress for their network chip, it is their identity. By activating the Mac filter, every "Mac IP" and by extension devices not authorized are kicked of the network.
You see it coming... I added the "MAC Ip" of my laptop as the only authorized one  and activated the filter. I was jubilating, I was like God, controlling the Internet fate of my fellow neighbors. Mouahaha. The victory spirit quickly fade away.

When I realized I got kicked out of the Wifi (as all other residents). I tried desperately to connect back to the Wifi in vain. I slowly realized that I had no possibility to modify what I had done. I must have made a typo when adding my MAC IP.

From there, I don't know what to do.
It is either I don't say a word, submarine mode. Some tenants will end up calling the landlord who will contact the Internet Operator. But i'm afraid they will discover I'm the reason of the mess.

Or tomorrow I will try to fix it by finding in which apartment the internet box is, making up some excuses to get access to the box to reset it. (I don't know very well my neighbors) Wish me luck !
<bot>: By greediness, I tried to exclude all other devices but fine. But accidentally blocked my access along with my neighbors one. So Internet is shutdown is for everyone.
