Wi-Fi

[Jijo]

My college WiFi has passwords only in student's devices, the teacher can give an application, including gadget details, to the office and there after the Wi-Fi is open to their devices.

So are you asking if there's a way to bypass this?

Sounds like it, OP should go research yourself or ask around.

 

Personally it there are some small tricks to bypass mac filtering but it illegal anyways. It much better to join the tech team at your college, if you can't beat it, why not join them.

Not allowed under community standards. If your in the US this violates The Computer Fraud and Abuse Act of 1986. Also, this will violate your universities WiFI policies. If they found out they could prosecute you or at the very least expel you from the school.

Not exactly, I wanted know how it works, how some registered devices don't have a password prompt.

The point is, you can't. How it works is probably mac filtering and proxy(squid), so certain devices don't require password prompt for internet access as it will be automatically accepted. You can't register your device unless you have access to their proxy server, this is really hard to bypass the authentication if they block all other service and only allow the proxy.

Because you want to know how it works, I am not advising any malicious actions and it is not my responsibility if you act maliciously.  I also don't know the setup exactly, and don't know your pre existing knowledge so excuse me. 

 

This most likely works via two methods, one is probably MAC address white listing.  This means only devices that have MAC addresses matching the white list on the wireless access point are authorized to connect.  It's important to know that MAC addresses can be spoofed, but this is a vulnerability of blacklisting primarily as it only blocks specified addresses.  To bypass white listing you would have to spoof your MAC address to match that of an already authorized device. 

 

This is most likely only to protect WiFi access and there is most likely a proxy server that is being used to limit internet connections, or at least connections to network resources such as printers and file servers.  Most schools use a Microsoft ecosystem because they get a discount and it supports all their, and the students needs.  And so it is most likely that they are using Active Directory (how you get to login with your own username and password into any school computer) to store and manage user accounts and permissions and then integrating Active Directory into a remote access server which they use to control access to the internet through wireless devices. 

 

This is of course not 100%, because I'm not a school admin and don't know if they are even running Windows.  Your administrators are good, because they priorities security. If you are interested in the setup you should ask them or ask someone at a tertiary institution.  Never try to hack past a school system, it's cruel to the underpaid administrators who work hard to operate and secure the network, instead you should do what I did in highschool, where I found a vulnerability in the system and instead of exploiting it reported it to senior administrator.

Hey..., I was going to ask him myself to accept the application form from students as well, don't worry, I had nothing malicious in mind!!!! Never!

And I appreciate what u did too....

I want to know how it works because of the same reason why u answered this question even though u thought u doubted.
