I just installed Ubuntu 14 on my laptop for the first time. After the installation I had no Wi-Fi connection. I went to "Edit Connections" and created a "Wi-Fi Connection", but don't know how to answer the questions such as SSID, Mode, BSSID, Device MAC address, Cloned MAC address, and MTU.

Can one of you gurus please help me?

Many thanks in advance and have a nice day.

If you have a wired connection, run in terminal

sudo apt-get install bcmwl-kernel-source

and Wi-Fi will work.

If you do not have a wired connection use THIS GUIDE.
