Similar issue here with E5-473G. I downgraded from Win8 to Win7. Then the Fn+F3 no longer work. The Launch manager in the support site doesn't support Win7. I obtain a launch manager for acer from other sites, installed it but nothing happened. Wifi still with red x. The Atheros Qualcome aapter is enabled its under Airplane mode. Is there anyway cmd command to turn off this airplane mode?
