Acer Aspire 5739G no WiFi/WLAN internet connection problem

I had the same problem as you, and for me I did the following and now it works just fine!

Code:

sudo gedit /etc/default/grub

you'll find
Code:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

change it to
Code:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"

update grub..
Code:

sudo update-grub

and restart
