if you know wifi is on, and enabled in the settings. Try going into control panel, find power options, change it so that its high performance mode when plugged in and unplugged. Also set it so the screen doenst sleep or hibernate

take a screenshot so I can see your msinfo32 and your device manager fully expanded if you can. That should def be something that comes up in the device manager. You may need to update the BIOS (though this is something that should work out of the box). If you still have support/warranty it might be a good idea to call Acer and ask
