Can't connect to WPA protected wifi. Prompt says choose a certificate OR enter account name and password? Huh

I cannot connect to wifi using my MacBook, my phone and Xbox work but there is no prompt for the WPA password and when I go to the diagnostics page it prompts me to choose a certificate or enter an account name and password? What account name are they referring to? I have entered everything I could think of; the actual connection name and password, the Internet provider login email, my MacBook account name as password... What the heck. After I try, it says connecting for awhile, then fails...
