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.
A dump of lsmod yields the following:
Module Size Used by
arc4 1195 2
rtl8192cu 89347 0
rtl8192cu_common 62334 1 rtl8192cu

usbhid 34524 0
gpio_keys 6801 0
rtc_ds1307 6350 0
rtc_twl 4402 0
Can you point me in the right direction? I've burned many hours on this and
would like to use this dongle for a 3D scanner we're building...
Thanks ahead of time!
Sincerely,

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.
I added my contacts at Realtek to the Cc.

Have you tried starting isc-dhcp-server after hostapd? I know in the past, hostapd
would delete and recreate the wireless interface.
