Cannot hard unblock wifi with Fn+F3 nor can I enter the BIOS to enable WLAN

algaebrown

My laptop is Aspire 4752G.

 

recently I changed my operating system to Archlinux, and after that I cannot hard unblock wifi with Fn+F3. So I wanted to enable WLAN in BIOS. But I cannot enter BIOS with pressing F2, either.However I can enter boot menu with F12.

I have already read previous threads stating that they cannot toggle Fn+F3 or they cannot enter BIOS in Acer Aspire series. Some suggest updating BIOS, but when I go to acer BIOS updates, there are updates only for windows operation system. All other solutions just didn't work. What should I do?

I am a newbie to all of these stuffs...so frustrated with the wifi issue...I will be very apprciated if anyone could give me some suggestions.... maybe save some money for a Mac computer...lol

 

p.s. I've already tried "blacklist wmi" to do something to the linux kernel. But that produces some other problems with netctl.

I have 2 questions. (1) Will Windows still start from the F12 boot mgr? (2) Do you still get the ACER logo screen on a cold boot? If yes, what happens when you immediately start tapping the F2 key upon pressing the power button before the logo screen appears.  Jack E/NJ
