It sounds like you have a problem with your Anti-Virus or Firewall. If you completely turn off both, and it works, you know this is the problem.
If you will reply with the name and version of your Anti-Virus Software I can give you more specific advice.

I've turn off firewall, AVG 8.0.191  is my anti-virus software. Everything work fine before it happen yesterday. I didn't re-configure anything on my laptop. I don't know why I can't even open the modem configuration page, is mean the local page. I've localhost (IIS) installed on my machine, but now I can't brow for it too (in browser)

Actually my original answer was the correct solution in this case. It is a common problem. I just did not have the benefit of knowing what Anti-Virus software you were using, so I was not able to give you specific instructions on how to fix the problem.
