I am using ubuntu 14.04. My wifi was working fine but after sudden it did not worked. I have googled over thousands of fixes and made as like the suggestion. But still I am not getting my wifi in working condition. I have made several restart the system but still its not working.

I have made this script in my terminal

```
wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

```

and the output what I got was like [this](http://paste.ubuntu.com/16082124/)

can someone tell me what exactly the issue is? How to solve this?
