I'm trying to setup a 4402 Controller and WCS in a corporate environment with a guest LAN using a bunch of 1131G APs.
I've heard that WPA2 is the way to go these days, but I'm having a hard time understanding whether or not WPA2 implies the use of 802.1X too. I'm fairly new to all this stuff, but based on my understanding it seems that WPA2 and 802.1X both do pretty much the same thing. That said, I can't seem to use one without the other. If I enable WPA2/AES with DOT1X on a WLAN, I can authenticate just fine but as soon as I disable DOT1X and use CCKM instead (I hear PSK isn't so secure), the AP no longer hears anything from my RADIUS server.
Is the use of DOT1X the only mechanism for communication with a RADIUS server (which puts the "Enterprise" in WPA2 Enterprise), where as CCKM would be more like the equivalent of WPA2 Personal?
