No Wi-Fi on Lenovo G50-45

Question

So I bought my son a Lenovo G50-45 for christmas and I'm setting it up (removing Microsoft Windows 10, installing Ubuntu 14.04 LTS and the essentials) for him...

But there's no wireless networking ("Wi-Fi") available, only "traditional" ethernet!

I know there's an integrated wireless card, so any help getting this going would be great...

Thanks!

I tried another solution for a Qualcomm Atheros device, however it had no effect... Yes, I restarted the laptop.

Edit 2: Nevermind - Ubuntu had some updates to install after the above; once I had installed those and rebooted a second time, everything started working fine.

Therefore, the original solution stands.
