I'm using a BeagleBoard-xM with Ubuntu 11.10 on it. The problem is with a NetGear WNA1000M using the RTL8192CU firwmare. I'm quite new to Linux, so treat me gently please! I'd really like Larry Finger to reply if possible, since he seems to have done the most work on this. What happens is I cannot connect to my wireless access point that has been setup using the following hostapd.conf: interface=wlan1 driver=nl80211 ssid=EnvisicAccessPoint hw_mode=g channel=1 auth_algs=3 wpa=3 wpa_passphrase=GoofyPhrase wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP CCMP rsn_pairwise=CCMP macaddr_acl=0 ignore_broadcast_ssid=0 ctrl_interface=/var/run/hostapd ctrl_interface_group=0 eapol_key_index_workaround=0 I already have isc-dhcp-server running in the background pointing to wlan1. I launch hostapd using the following command: hostapd -dd /etc/hostapd/hostapd.conf I get a bunch of output to the console, and when I try to connect using my Windows 7 machine, it seems like it's trying to negotiate a connection, however it does not succeed and repeatedly gives me the following in the output log: WPA: 00:1a:73:bb:f8:11 WPA_PTK entering state PTKSTART wlan1: STA 00:1a:73:bb:f8:11 WPA: sending 1/4 msg of 4-Way handshake WPA: Send EAPOL(version=2 secure=0 mic=0 ack=1 install=0 pairwise=8... wlan1: STA 00:1a:73:bb:f8:11 WPA: EAPOL-Key timeout Eventually it unauthorizes the port and deauthenticates it. I'm not sure how to proceed so as to get a proper connection. My BeagleBoard has the drivers stored at /lib/modules/3.1.6-x6/kernel/drivers/net/wireless/rtlwifi/rtl8192cu and the firmware stored at /lib/firmware/rtlwifi.

I've burned many hours on this and would like to use this dongle for a 3D scanner we're building...
I was the person that took the Realtek vendor driver, and reworked it to meet Linux standards for kernel code; however, I have never seen any documentation on the hardware, thus my ability to fix things are limited.
I know that rtl8192cu does not work in AP mode, and I have spent some time trying to find out why, but I have had limited success. The driver transmits beacons, and starts the association process, but it never really transmits data packets. I'm certain that it is only a minor point, but so far there is no solution.
It is possible that the drivers on the Realtek site might work in AP mode, but I have no experience with that. I would certainly recommend that you try them to get your product working. As I recall, there are two varieties - one that has its own MAC layer, and the one that uses mac80211, which is the one that I converted. To use hostapd, you will need the latter.
