Hi, I installed Ubuntu because I want to learn how to use it and I also love the fact that it is open source. So, i bought a new laptop, Lenovo Z51 and installed Ubuntu on a different partition. I was happy that the installation was successful. Everything worked like a charm. But then I realized that I was connected to the internet via a wired network. So, I removed the cable and tried to locate the wireless internet connection on the top of the screen. It wasn't visible. I tried a lot and read about 50+ community articles. Then finally, I thought that I should ask for the help from some experts. I used the wi-fi script and generated wireless-info.txt and opened it to see a bunch of codes that I don't understand. Please help me. Here's the code:
