Windows 7 cannot recognize wireless card  

Hello,


I am experience a very perplexing problem. A couple of days ago my wireless card, an Intel Centrino-N 6230, was working fine. At they end of the day I shutdown the PC. The following day, when I booted it up, the little WiFi indicator in the task bar had a red "X" on it, as if the switch was off. It is set to ON and still acts this way. I tried updating the drivers, both from Intel's website and my laptop manufacturer's website.


I have a Sony VAIO VPC2MFY/B, if that helps.


I have had this problem before and solved it simply with a System Restore - the problem had always been because of a "Critical Windows Update", and the funny thing is there was always TWO of them. Naturally, the first thing I tried was a System Restore. Sure enough, there were two critical Windows Updates, and I selected the initial one (as I did before). On reboot, however, the problem persisted.


It usually fixes it. I ran the built in Network Diagnostics and it reports that the hardware switch is disabled. I had a utility from Sony that diagnosis wireless issues and it reported that drivers, software, config, and everything was correct, but the radio (hardware) switch was disabled.


Can someone please help? This is really agonizing.


Thank you.

I fixed it.

I decided to see if my Ubuntu-Linux installation had anything to do with it (I have a dual-boot). Using the terminal I found that the WiFi card was detected (thus, not defective) but simply hardware disabled (via software, if that makes sense) by Ubuntu itself. I undid that, and Ubuntu connected wirelessley.

I booted into Windows and it instantly connected to my home network.

In case anyone is wondering, I got it all from here:

The difference is, unlike the guy in the above post, it worked for me.
