My new Intel NUC D54250 WYK , I installed windows 8.1, having AzureWave AW-NB159H WiFi-blue tooth module. WiFi and Blue tooth is not working, Windows device manager 'Other device' showing question mark, ie. Network controller and SM Bus controller.Try to update the drivers but driver not found message is coming. Used Intel Driver Update Utility application and install new version of all the drivers but other than Chipset Device Software for Intel Nuc Ver.10.0.14 and CIR Driver Ver. 2.9.1007, are installed. These two are failed to install. LAN is working OK. Anybody can help?
