Are you sure that you setup is correct?
For example you can not connect to AP which require RSN authmode
if you configure wlan0 for OPEN authmode, you also may not
connect to AP if you are far away, because you are able
to receive and send doesn't mean AP can see your packets ........

Try changing ucastrate to lower values.
