ကြ်န္ေတာ့္ အေတြ့အျကံုအရ ubunutu မွာ wireless driver တကူးတက သြင္းစရာ
မလိုဘူး။ ဒါေပမယ့္ ubuntu 12 xx လား 11 xx မွာလား မသိ တစ္ခါ ျကံုဖူးတယ္။ upgrade လုပ္တာျဖစ္ျဖစ္ ubuntu version အသစ္ျဖစ္ ျဖစ္ သြင္းလုိက္တယ္ အဆင္ေျပသြားတယ္အခု 14.04 နဲ့ 14.10 သံုးေနျကတယ္။ အစ္ကို က ဘယ္ version
သံုးလဲ ??

have u tried configuring network from terminal.
Type "ifconfig -a" (without quotation marks) and check the output. If there is wlan0, your OS detect wireless device.
pls check lsusb.
 it's your driver name and code

First, find wireless switch or key combination is turning off the wireless or not. Then, simply type this command.

rfkill list all

sudo rfkill unblock all

rfkill list all
0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
1: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: ideapad_bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
Since Soft/Hard blocked are both no, it should be working. Still having error? Type `rfkill list all` again after typed `sudo rfkill unblock all`. And reboot.

I got same problem on my Dell laptop and acer aspire V5. Here is my tricks to install wireless driver on ubuntu. Hope it should be ok in your lenovo as well.

1) Connect to internet with USB tethering from mobile internet. (tethering not need driver configuration)

2) Then run, sudo apt-get update in terminal

3) Open System Setting > Additional Driver

4) Install wireless driver from there
