Dell Inspiron 3521 WiFi connection issue

Question

I've just bought a Dell Inspiron 3521 laptop which came with Ubuntu on it. I formatted the hard disk and installed Windows 7. All fine and dandy, until my WiFi kept disconnecting randomly. At first I thought that it was my connection, but the other laptops in my home didn't have this problem, nor my iPhone did. Now, as soon as I connect to my WiFi it disconnects me. This is extremely annoying, because I have all the latest drivers, I even updated my BIOS, because it was suggested in a thread where the same issue was presented to you. I hope this isn't a hardware issue, just a driver one, or something that can be fixed through Windows. I have to say I tried every method that Dell Support suggested in the threads that have the same issue, like drivers, BIOS, power management, Safe Mode, etc. I'm not a computer newbie, so if there are more complicated solutions that do the trick, I'd be more than happy to use them, just don't tell to update my drivers, as this has been told a thousand times on this forums, and it hasn't resolved the isssue.
