[PLUG] Linux Mint on Intel iMac /w/ Airport Extreme

TL;DR; Resurrected iMac has WPA2 problems

I got an old iMac with a dead drive. I pulled the drive and installed an SSD. It is now running Linux Mint but I cannot get the WiFi to work right. I can see networks but I cannot connect to them. Since I can see the networks in my house (and my neighbor's) I think the hardware is ok.

My main networks are WPA2 security.

I can connect to an old WEP security network.

So the problem looks to be in the WPA stuff. Note I am using Mint because Ubuntu didn't work. I was hoping a different install of essentially the same thing would have different results. If there is a better *nix variant to run on this hardware I wouldn't mind changing at this point.

Anyone have any suggestions? My hardware is below:
