Try preamble-mode both? I think there was some trouble with selecting either long or short.
And you don't need to capitalize SSIDs. The test network I am using has a lower case SSID.
export verbose posted so that you can compare. I didn't do anything special, just set a channel, SSID, security profile and, voila!
Now that I see it, I disabled WMM by mistake (or forgot to enable it, I don't remember). Anyway it works I think. As you can see, almost everything is set by default.
