Dlink setup for University dorm

I am trying to setup my d-link dir-615 router using the existing network in my dorm room. I know I have to disable the DHCP server. But as soon as I do that, I can't get back into the router's interface. I know I also need to mask/spoof the MAC address of my laptop. I am told that there are scripts running in the existing network that look for wireless routers, and if it sees the MAC of a wireless router, it disables the port on my wall. It's happened once already, got it turned back on now, but I need to be careful. On linksys I've heard of Phantom Mode or Spoof Mode, something along those lines. If anyone has any idea of how to set it up, PLEASE HELP!

 

It isn't truly against the rules. I spoke to one of the IT guys there, and was told they tell people that because most people don't know the proper way to set it up (ie. placing a bunch of routers with DHCP enabled will cause network conflict). If you set it up the right way it is harmless. There are other SSIDs that I see when I turn on the wifi on my laptop, you can tell they arent university SSIDs so I know it is possible, I just cant tell how. I can't tell where the signal is coming from either, or I would just go ask to copy their settings, hah.

 

He's telling me he would have to come up to see the router interface since he's not familiar with it specifically, OVER THE PHONE. I'm here asking for some help, not sarcasm.

 

First off, you need to know the characteristics of the existing connection to the network.

Connected directly to the network, let's see this.

Hold the Windows key and press R, then type CMD to open a command prompt:

In the command prompt window that opens, type type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.
