Wireless adapter not working

[italifin]

Hello,
I need help! Two days ago my wife's computer would not connect to wireless networks anymore. It said that "No connections are available". It used to tell us to turn the switch in the front of the computer on, however it is on. (Now it will not troubleshoot, I receive an error during troubleshooting). Further the device manager says the network adapter (Atheros AR9285) is working properly. I have spent two days trying everything that I can find on the internet without being able to resolve this problem. I know the wireless router is working properly because I am using it on my computer. Does anyone have any suggestions?
Your help is appreciated.

Hi Italifin, welcome to sevenforums. Do you have the wireles signal strength bars showing in the system tray at the bottom right? (It looks like 5 vertical bars of ascending sizes) If you do have it, is there a red X through it or a yellow circle?. If either of these, right click on it and select to "troubleshoot connection" and see what the troubleshooter comes up with.

Hello wilywombat, and thanks for your assistance. When I used troubleshooter to resolve the problem it sais I needed to turn on the switch on the computer. The switch was already on. Since the computer is a Sony I went to sony help and got a technician to look. He discovered that the Smart WiFi utility had the switch turned off. Apparently I had turned this switch off by accident. Actually I didn't even know that it existed. The way to turn it back on was to click start, then key in Smart WiFI in the search box, then click on the Smart WiFi connection utility and voila there was the switch. One simple solution to a perplexing and frustrating problem. I am very appreciative of your assistance.
