I looked at that yesterday, and sadly I _think_ it's not even possible, there are some corner cases in it like "no WPA2" that don't seem to be fully covered in cfg80211/nl80211, at least not with the APIs today and with current versions of wpa_supplicant. It might still be doable because things like WPA_DRIVER_CAPA_KEY_MGMT_WPA2_PSK don't really seem to be used much in wpa_supplicant, but we'd have to carefully test that I guess. Also, it depends on the PS3 firmware version whether or not that's supported. Then again, arguably wifi without WPA2 is pretty much useless these days? johannes
