I'm completing my build with a cooler master storm stryker running windows 8 pro 64, with a gigabyte Z77X-UP5 TH when I try to connect to wifi/ LAN I get limited connectivity. I've tried downloading the driver from gigabyte and also from the atheros/ Qualcomm website but all windows 8 device driver manager reports is that the latest driver is installed. Any help would be appreciated because I'm running out of ideas..!
