just dont forget that, you can kick people off as much as you want, all it takes is about 2 minutes for them to sign back on... which kinda defeats the purpose of what you want to accomplish, you need to block their MAC add from the router to keep em out...
honestly for someone with as much experience as you i would just recommend getting a 4g AP for like 30 bucks a month... theres more to hacking than just using a program to kick someone out, youll never accomplish much unless you know exactly what that program is doing how and why its doing it, and understanding the TCP/IP protocol and its layers wouldnt hurt either...

Yep, i know about that MAC Filtering. But i need the password for the router which is throwing me to phase 1. That 4g AP in my country doesn't exists. Except for a limit of 13 gb/month. I'll do my research to get in to other things that using a program.

I do indeed know the manufacturer cuz i am connected on wi-fi on this router. I pretty much have on my hands few infos, cuz when you check in on a motel, they give you their wi-fi password. I can aswell enter on the log-in page but can't modify anything cuz i don't know the admin password. Usually, ppl that have motels change it from the default one. Ok, i'll start up from here, learn more about this brute force entry.
LE: To get into hacking, maybe it'll became something i like to do, i need a pretty good laptop? I mean configs. Or even a dual core would do the thing? I've read that for brute force, i need kinda good stuff in there, at least if i don't want to wait days to get a password, am i right?

Hello, ppl. I'm a random guy who haven't hacked a thing in his life. I'm working all over the country and i'm forced to deal with all kind of crappy internet connection, mostly because there are too many ppl checked in motels and the host have a 100 mb/s ISP connection, which divided to 20-30 ppl results a shit. I'm over with it cuz i spend my freakin' weeks like that. The only thing i want is to get in to a damn router and change the wi-fi password or kick ppl out from the connection, etc. How can i do that if the guy have changed his router password on the administrator user and i'm stuck with the read-only user to log-in to his router. Is there anyway i could bypass the password for administrator privileges? I can't watch even a damn youtube video because the connection is too slow. Most of the routers used in my country are TP-Links, D-Link, Asus maybe, ZTS. Pretty much standard ones. I would really appreciate if you could help me. Ty for reading. Take care.
LE: What if the router i'm trying to hack in to has receives internet from another one? Like linked to have a a better wi-fi signal to an upper floor. Does it changes anything?
Factory resetting a router deletes any changes you've made in to? Like maybe the guy have a port forword for security cameras or dmz for same thing. I don't wanna fuck everything up. Just kick ppl out or change the password so i have internet cuz i'm living anywhere else except home these days. I'm not expecting to give me full tutorials or translate them to me. If you can, just give me a link where i can find things easy to understand and i'll read.


And as i final add. I'm connected to their router by wireless with a laptop, running windows, not linux or whatever. Is it a problem? I might need to take a UTP with me and sneak to the router to get that kind of access?
