Fn+F3 should enable it (at a quick search I saw the Wifi symbol on F3 button, please recheck, of course)
Also, please do not cross-post. I'm going to hide the other topic.


Er... oh well forget. I do understand there's a language barrier.

If there is a hardware button to enable/disable the wifi (sometimes called "airplane mode") make sure it's not off.
On one old Acer I used to have, it was one of the led lights on the front, it also acted as a toggle push-button.

Also, make sure to try the Fn+F3 advised above.

Failing that, try

sudo echo "blacklist acer_wmi" > /etc/modprobe.d/no_acer_wmi.conf
rfkill unblock all 

this may or may not need a reboot afterwards, I'm not sure.
If it doesn't work, remember to delete that file (sudo rm /etc/modprobe.d/no_acer_wmi.conf).

Finally, it may even be the case it needs a little hardware tinkering (I really hope not): debian - WiFi hard blocked after updating BIOS on HP laptop - Unix & Linux Stack Exchange
Don't do that unless you are very sure. Get back to ask for advice here.
