If you have a wireless switch to enable / disable wifi then press it. If not then run:

sudo rfkill unblock all

Then retry

Yes there is a hardware wireless switch and i turned on it. also tried to Fn+F5 but the wireless don't tuned on.

I have tried "sudo rfkill unblock all" even restarting the computer but still doesn't work.

1) First please follow the suggestion from forumuser Wilson Britten (wilsunb) at the end of the following thread:

https://answers.launchpad.net/ubuntu/+source/gnome-nettool/+question/169971

So first flash your BIOS to the newest BIOS version for your Lenovo V570

2) Second issue is the following Terminal output that you sent us:

0: phy0: Wireless LAN
 Soft blocked: yes
 Hard blocked: yes
1: ideapad_wlan: Wireless LAN
 Soft blocked: yes
 Hard blocked: no
2: acer-wireless: Wireless LAN
 Soft blocked: yes
 Hard blocked: no

Please read the last remark from Ultraman at the following location:

https://bbs.archlinux.org/viewtopic.php?pid=924554

Ultraman solved it by blacklisting the acer_wmi module, which your computer has loaded into memory.

Please copy-paste the following command into the Terminal and then press <ENTER>:

gksudo gedit /etc/modprobe.d/blacklist.conf

Using the gedit editor, please ADD the following configuration line into the file:

blacklist acer_wmi

Using the gedit editor, SAVE the change to the

/etc/modprobe.d/blacklist.conf file.

Then REBOOT and retest wireless. This blacklist operation should make the change permanent, even after rebooting.

This should force the Linux kernel to stop loading the acer_wmi module, which is probably causing the kernel to soft block your wireless card via the INVALID "acer-wireless: Wireless LAN" interface.

acer-wireless is for ACER computers, not for Sony or Lenovo machines....
