This means that the scan results did not find an AP that wpa_supplicant
considers useful.  Do you have an SSID specified in the network block?
Can you provide output of 'iwlist ath0 scan' (hide BSSIDs if you wish)
and tell us which AP you're trying to connect to?

This means that you don't have a compatible network block specified in
the config file, and therefore wpa_supplicant triggers a disassociation
because you're not supposed to be connected to this AP.

So you don't appear to have any valid networks in your config file.
That's the root of your problem.  Make sure you have every network in
the config file enabled and valid.
