Hi,

Please first connect your wired network adapter to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1:

If you are using the Gnome interface, open the Terminal console via "Applications->Accessories->Terminal"

If you are using the Unity interface, the easiest way to open the Terminal is to use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.

So the methods in Unity are:
Dash > Search for Terminal
Dash > More Apps > 'See More Results' > Terminal
Dash > More Apps > Accessories > Terminal

Step 2: Please copy-paste the following command from https://help.ubuntu.com/community/WirelessTroubleshootingProcedure in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word lsmod. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.

Your Terminal output shows the following first issue:

1: ideapad_wlan: Wireless LAN
Soft blocked: yes
Hard blocked: no
2: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
3: 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....

Second issue in the Terminal output you sent us:

4: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: yes

So your wireless card is probably ALSO disabled by a hardware switch, a
special key combination (Fn-F2, etc...), by incorrect BIOS settings for
wireless, or a COMBINATION of these factors...

There might also be a BIOS option that allows you to have the wireless
functionality controlled "By application"

Search for the "by application" option in the BIOS and select it (if
possible)....

Then reboot and retest wireless.

Also run the following Terminal commands to try to change the rfkill
state of your wireless chipset after rebooting:

rfkill unblock all

sudo rfkill unblock all

Then retest wireless .
