Vostro 1014

I just bought a Dell Vostro 1014 dual core processor t6570 @2.10 ghz, 3 gigs of ram off of craigslist, and It had windows xp on it and I just upgraded it to windows 7 64 bit, I did a complete clean installation, everything installed like normal and windows is registered, well with windows xp everything worked, and now that I have upgraded to windows 7 I find that I am having quite a few issues, going back to xp is not an option because I dont have a license for it, since it originally came with windows 7 and somebody had put windows xp on it. one of the first problems I came accross was getting the webcam to work with the creative lab software that came frome the drivers and download support section of dell, I finally got the webcam to work by installing Arcsoft Web cam, and that was one problem fixed, another problem I had after that was getting the bluetooth to work, Dells drivers and downloads support only gave me a partial file for what ever reason and I finally had to download a 75 meg file from another site and I finally got that working, now the main problem I am having right now is getting the Wireless to work, if I connect a wired ethernet line to it it works fine but the wireless is saying that there is no available connections found, now I know this is false because I have 2 other laptops. 2 ipod touches, a Wii and a PS3 all finding the the wireless just fine, its just this laptop that cannot find it, it has an Atheros Qmi network wireless card in it , the device manager says the device is working fine, and when I run the network troubleshooter it says that their is a problem with the device driver, now I have went to the Atheros website and downloaded the updated 64 bit driver but it is still not working so I know I have the latest driver... I even tried uninstalling the device and re-installing the device, but still no luck, it worked with windows xp as I had used it before upgrading to 7.. everytime I try to manually add a wireless point it just gives me an unexpected error, and then just quits, when I tried to do a search for any available access points it says it may take up to 90 seconds to find a connection but Ive left it running for an hour or so and came back and nothing.. I have tried Hiting the Fn + F11 key to turn the radio on but nothing happens there either, went into bios. and everying is enabled there how do I know that when I hit the Fn + F11 key that wireless is on or off?? .. I am now at the point of frustration at the problems of purchasing this laptop, everything else so far is working fine as far as I can tell except the wireless anybody have any other ideas I can try... also something else I noticed this past weekend, on the dell drivers and download site, everytime I have either entered or let the site scan for my service tag number they would show all the drivers and files for it and the warranty information for it , but now all it is telling me is that there is no available download or information for this service tag?? but if I just manually enter the model number it shows everything again, and body have a clue about that one??.. Sorry about the long post but I wanted to be sure to put in everything I can think of... any and all help is appreciated.. Thank you..
