I want to print out a QR code for a Wi-Fi hotspot, so other people can easily connect to it with their iPhones and such, and the QR-code-maker has me choose between "WPA" and "WPA2".

How do I find out whether a Wi-Fi hotspot, in my MacBook's Wi-Fi history, is WPA or WPA2?

In my Wi-Fi network list, it's listed as "WPA/WPA2 Personal". I assume that means "try WPA2, and if that doesn't work, then try WPA". Is there any way to tell if it actually used WPA2?

You can find this out by holding Option and clicking on the WiFi icon in the Menu bar.

It will open up a "menu" with additional options and details including the type of security you're using.

If you see your network say WPA/WPA2 Personal, it means it supports both. This is what the Access Point supports. In my case, I disabled WPA (and thusly it doesn't show up). You can choose either QR code and the client will be connected.
