Setting up a RTL8188CUS 802.11n WLAN Adapter

[Csanyi Pal]

Hi,

I want to setup my Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN
Adapter as a Wireless Access Point, sofar without success.

I'm running a kernel version 2.6.39.4-13 with rtl8192cu kernel module
support. 

When I plug in the USB WLAN Adapter, the wlan0 interface appeares:
$ sudo ifconfig -a

eth0 is my wired NIC to my ISP through a cable modem.
eth1 is ma wired LAN NIC.
wlan0 should be my wireless LAN NIC.

I'm trying to follow these steps:
http://wireless.kernel.org/en/users/Documentation/hostapd

I have the file: /etc/hostapd/hostapd-minimal.conf
interface=wlan0
driver=nl80211
ssid=test
channel=1

When I run:
$ cd /etc/hostapd
$ hostapd ./hostapd-minimal.conf

I get:

Configuration file: ./hostapd-minimal.conf
Could not set interface mon.wlan0 flags: No such device
nl80211: Failed to set interface wlan0 into AP mode
nl80211 driver initialization failed.

What am I missing here?
Any advices will be appreciated!
