WPA2-AES (without mixed, without TKIP, as you've shown in your screenshot) is still quite secure. WPA is nothing like WEP (which might as well just be open with today's technology). There's been some attacks against WPA, but WPA2 is basically only vulnerable to brute force attacking of the passphrase, which is more of a problem with preshared key and probably lesser of an issue with Enterprise as you shown.https://en.wikipedia.org/wiki/Wi-Fi_Protected_Access
It's really not the bits of encryption that screwed over WEP and WPA1, it's fundamental design flaws in the cryptographic scheme. They seem largely resolved with WPA2.
