I hate to resurrect an old thread, but I'm in search of some more up-to-date info on this topic.
I am also trying to bring up a WPA2 AES (CCMP) AP using airbase-ng but I'm not having much luck. I am using the following command:
# airbase-ng -c 6 --essid "test" -a AA:AA:AA:AA:AA:AA -W 1 -Z 4 -V 3 wlan0mon
I have a Windows 7 host which throws up an error when trying to connect, and a Windows XP host which seems to momentarily connect but then drops off. This is the case when using -z and -Z. I've also tried a few variations such as removing the -V and -W arguments, but I get the same results.
I've also tried no encryption and WEP encryption, which my Windows host can successfully connect to and ping the at0 interface.
I'm running this on Kali Linux with airbase-ng 1.2 beta2 and an Alfa AWUS036H (rtl8187 chipset with the mac80211 driver).
I haven't yet taken proper analysis of a packet capture, I shall be doing that in due course but I'm by no means an expert. Happy to provide any dumps if that would prove useful. Any thoughts from anybody?
