Well, my neighbor in my dorm went in with me on a cable modem and he got a wireless router and some how he messed up my internet settings, I would have set it up but I had class. Now I can't connect to any wireless network what so ever. I can get the signal fine but when I check airport's settings it says i have no ip address or a self assigned ip and won't let me connect. And also, there's a VPN thing that showed up in network status window. I'm hard wired to the router and that's the only way I can get online. He was paranoid about people freeloading off of it and tried to make it "secure" but he just ending up securing me out of it. So what I'm wondering is if there's a way to just reset all of the internet settings to default and just do it myself this time. If anybody can help me out I'd greatly appreciate it.
