Yup. LOL... Like your access point name.
However, looks like it is already set to AES. Just for kicks and giggles, turn off wifi security (temporarily) and see if your problem goes away. If so, then the problem is probably related to the encryption key/encryption used in the wireless security.
If that works, turn security back on and use a password with numbers and letters only. IIRC, back a while ago, some phones (a moto RAZR MAXX that I had) had issues with complex wifi passwords.
Give it a try.
