I just got an older macbook air from a friend and it was running a bit slow so I decided to use Ubuntu! I have used Ubuntu in the past but I'm sort of a newbie so please bear with me.
When I installed it was 12.04 which i have fully upgraded to 14.10. In doing so my wifi was not working. I have gone through a lot of posts on this forum yet none have fully resolved the issue. I do however have it to where it looks like the wifi should be working yet no networks are being detected and I am in need of some help (i can bluetooth tether from my phone for temp internet connection)
here are something I have seen in other forums that may be helpful.
