I have an Aspire V3-771, this morning when I powered on the wireless connection is Greyed out with a Red X over it showing the wireless is turned off. In the Connections setting it shows as enabled, the troubleshooter says turn it on using the switch or Fn F3, I can't find a switch, Fn F3 puts it into Flight Mode and Back out of Flight Mode but still shows as off. I have tried all of the following but still shows Off:
Enabled it in and dissabled in the network connections
Turned it on and off in the Acer Device Fast Lane
Done a restore back to a restore point 1 week ago, Microsoft did do an update yesterday (7/1/13)
Updated the Driver to 10.0.0.217(New) from Atheros site
Un-installed McAfee AV software
I contacted Acer support who suggested a full system Restore to Factory Settings, having spent 2 dats getting it setup I am loathed to do this as I do not think it will work.
Has anyone come across the same problem before I waste the next 2 evenings re-building....
I put my acer w700 into airport mode to turn off my wireless when i first got it to try it out but the wireless stayed off when I turned off airport mode. The only way i could turn it back on was using change pc settings on the right hand swipeout menu and selecting wireless. From there i could control bluetooth and wifi connections directly. Hope it helps.
I have the same problem. And no solution, as I can't update the BIOS (am running the latest version). Also, my computer does not run a UEFI BIOS: it came with Windows 7 and was later upgraded to W8 by me). So I'm stuck ( Nobody from Acer is going to give us a solution?
I had to register here and comment.... I tried EVERYTHING....including the other suggestion to just reboot, F2, and so on.... and clicking F2 did nothing....nothing came up. However, I followed your video and it worked right away. I am pretty sure you saved me hours and hours.....THANKS!!! Also..... @ Eriquep.....hopefully by now your issue is fixed, but if not... when I went to run this... there was on option before for Windows7, Windows8 (upgraded from 7) & than of course the original Windows8... Just so you know... The only other thing is that I really hope I did this right and there won't be any future problems with my laptop because of it... and if it were to have caused a problem I'm hoping that it is something I would know right away!! Just did it...but, so far so good:-) Thanks Again!
Aspire M851TG here. Same problem all of a sudden today. Found the BIOS video on Youtube and it would not install. Oddly enough... hold on to your shoes... I installed the windows updates from the Metro settings panel and it fixed it.
