I just bought a Sony Vaio a month ago (model VPCCw21FX) has Win 7 and Intel 3. The wifi at home is fine, but when I try to connect to the wifi at work, it can detect but somehow I cannot connect. At work, there is another connection that I'm able to connect to but since I don't have an account with it, I can't get on the internet.
I did all the troubleshooting, call Vaio tech support and did all the uninstallation of the wireless and reinstallation. I even went out and bought a wireless adapter and still it was doing the same thing. It can detect but it won't connect. I tried it on my work desktop and it was doing the same thing too. But everyone could connect to the free wifi at work except for me :(
