from “ifconfig”, you don’t have IP address assigned for your wlan0 or wlan1, one of which (should be wlan1) is the sta interface. It means that DHCP is not successfully in this interface.

I don’t know why, but the firewall seems just fine.

Maybe there is a bug in this bleeding edge firmware. Can you show output of “ps -w”?

Does your main router support DHCP?
