I'm looking for a possibility to make my desktop WiFi compatible. Currently I'm using a USB-stick that connects to the router, but it's not the best solution as it sometimes loses connection and isn't made for continuous service.
Thus I started looking and found that PCI cards have better performance. My current pricing wish would be around 30€, but it wouldn't be a big deal if it cost more. My Mainboard is an ASRock Z77 pro4 and the only PCI slot I'm using is for my graphics card (This graphics card blocks the neighboring PCI slot).
I want to sometimes play online with the card, so connection quality should be as good as possible and several hours of operation should be no problem. I'm using Win7 and (arch)Linux.
Note that I'm not up to date on the PCI standard, so I use PCI to refer to PCI-e, 2.0 and 3.0 interchangeably.
