Problems with Intel Centrino Wireless-N 2230

Hello All,

I am not sure whether this is even the right forum. Please pardon my ignorance, if it is so.

For last two weeks, wi-fi has not been working on my windows 8 machine. Wi-Fi switch is a software based switch on my machine. It is ON when I start the machine. But it does not list any wi-fi networks (I know the existence of the networks as I am successfully getting connected to those networks using my other devices). If I switch off the wi-fi, I cannot turn it on unless I restart the machine. The problem persists in my house as well as my office. We don't have any technical person in the office as I work for an NGO.

I don't know whether it is the windows update or installing Intel PRO wireless suite.

Here are the things I have tried:

• Uninstalling PRO wireless software
• Rolling back to previous version of the driver
• Uninstalling the device using device manager
• Just updating the driver to the latest version from Intel's website
• Uninstalled all the windows updates of last two weeks
• Changing the power setting to keep the wi-fi on and under maximum performance

I don't know how to solve this problem. I am using wired connection for last two weeks.

My machine is - MSI Computer Corp. Notebook GT60 0NC-004US;9S7-16F311-004 15.6-Inch Laptop

Operating System: Window 8 Pro 64 bit

Wi-Fi Card: Intel Centrino Wireless-N 2230

Here is the result of my ipconfig /all:
