I created wireless profiles according with my router settings in my machine but still I cannot have the wireless. I changed some other settings there too but no joy and everytime I uninstall and install the driver, it gets its original settings. I changed Roaming Aggresiveness as highest and again no joy with above combinations. Then, I tried out to configure the adapter settings from advanced tab by clicking configure on the adapter. Then I tried out hdwwiz.exe and manually adding driver with the above combinations and still no joy. I found out all drivers from detail and delete them but no joy. I say, hmm, although I uninstall the drivers from device manager, let's delete those drivers manually. I say ok, let's try out Intel's original driver that it detects in its site, same thing occurs. I say ok, let's try out VAIO Vista driver, same thing occurs. I say ok, let's try out for VAIO original 7 driver and no joy again, everytime it fails and I got windows was unable to connect to error.

Then I failed to connect my wireless network. The issue starts while I was installing 7, 7 says ok, let's connect net, I input my credentials which is 8 character with WPA (not WPA 2 since router has no support for this) I have a problem with reputated VAIO and Windows 7. Before reading the question, keep that in mind that the wireless driver in the device manager has no x or ? signs and 7 says ok, I recognize your driver perfectly without an issue, so put it simply, my problem looks like some halloween issue.
