Could you try to load it manually with "ifconfig wlan0 up" or "modprobe
hostap_pci" and see whether you get any more detailed error? And check
what 'dmesg' shows after this.

Master mode is different from "Mixed" mode, but yes, based on your
explanation, being in Master mode is indeed a problem for this
configuration. Host AP driver uses Master (AP) mode by default. If you
want to use it to associate with another AP, you will need to first
change the mode to Managed ("iwconfig wlan0 mode managed") (which is
exactly what that iw_mode=2 parameter was trying to do).
