I'm setting my wireless environment.
I have to use WPA2 Enterprise with PEAP and have to use AES encryption. But I can't find where encryption config is. (MS-Windows has the option)
How can I config it?
From this link you will see that AES encryption is part of the WPA2 Enterprise protocol.
Note the heading: Version
And the heading: Encryption protocol CCMP
This is why Kevin in his answer is able to say that he never has a problem connecting even though he has to meet the same requirements as you.
My work wireless network has all the same settings including AES. I never have a problem connecting. It makes me login twice. I am guessing it is trying different options. But after the second login I am connected.
