Wi-Fi Not Working On Ubuntu 13.10 MacBook Pro

Hi Everyone!

I'm new to Ubuntu and I decided to install 13.10 64bit on my mid-2010 MacBook Pro and since I installed it I haven't been able to connect to a wifi network. I tried installing Ubuntu on a Windows PC but the wifi didn't work on that because of the network card. If my wifi problem is because of the network card than I can't replace it since it's built in so does anyone know how to fix the wifi?

Thanks
