I was on the internet, opening an attachment, and it used Microsoft Startup 2010. I hadn't used it before, so it was running updates while I was in the middle of working. Pop-ups appeared, asking for permission to connect Microsoft to the web to finish running everything. I thought I could do that later and stopped it from connecting. Since then I haven't been able to connect to the internet. The laptop recognizes a signal coming through, but it says it has limited access when I open the wireless menu, but if i just place the mouse over icon, it tells me "No network access.". I've restarted the wireless modem and laptop, I've run the trouble shoot program (resulting in: "The default gateway is not available." I even did two system restores, using the Microsoft updates as starting points and still nothing. I'm at a complete loss.
