    My laptop suddenly has the ability to disable any network it's connected to, whether or not I have the password to it. Here is the video of it in action (but please read the caption below before watching the video):

    Also please note, I have the "Magnifier" application up only because it stays on top and blocks people who watch the video from seeing my personal info (IP, MAC address, etc).

    Here is the video:

    I've always had an icon in the lower right called either "Local Area Connection" or "Wireless Network Connection" depending on if I'm hardwired to the router or wireless. About a week ago, a second icon started appearing alongside either of the other two. It's called "Internet Connection" and when I look under the networking section of control panel, it's located under "Internet Gateway". So I went through the network connection wizard and told the wizard that I connect through a router, and NOT directly to the internet like it seems to think. This has done nothing, no matter how many times I went through the wizard, the icon stayed even after I restarted the laptop. Even worse: if I try to disable that specific connection, everyone on the network loses internet.

    Infact, I was sitting in class one day when I didn't know what the icon did. I tried to disable it because I was afraid people might be connection through my computer or something, and when I disabled it, half the building (whoever was connected to that router) lost internet access. The technicians had to come in, and I felt obliged to speak up, and I actually got in a lot of trouble because they thought I "hacked" the network. Mind you, I don't have the password to the router, only the WEP key, not the admin login password.

    Upon further investigation, I found that disabling "Internet Connection" released the DHCP of the router, and in order to get internet access back, you would need the password for the router, login and renew the DHCP, as shown in the video.

    Is this normal for my laptop to be able to do this?
