Internet limited access problem

[Bravemarine1611]

Hi there
I am using window 7 home primium 64bit on my Asus laptop.
I had connected the internet at 4 am, but I couldn't have connected the Internet from 9 am til now. The wireless network connection shows 'limited access'.
My roommates can access the Internet by their laptops and I'm using my iPod touch to write this now.
I believe there is no problem in Modem or router. It is not about security key issue, too. I was using the Internet even in the early morning.
It is very weird that the Internet doesn't work although I didn't do anything but shut down and turn on my laptop.
I have been searching websites but I couldn't have found the same problem like mine.

Please help me smart guys.

This article describes all the netsh wlan commands you can use in Windows 7 or Vista to collect information about your Wireless connection, especially when you are having problem.

Open a command prompt and enter

netsh wlan show all > netshwlan.txt & notepad netshwlan.txt

That will capture all the available information about your wireless connection, direct the output to a file called netshwlan.txt, open Notepad with the contents of that file.

Post the content here if it's not too big, otherwise use the paperclip options (must use the Go Advanced button below the message input area button to access it).

If you redirect the output to a file when things are working then you can do the same when things are not working and compare them to see what, if anything has changed.
