Can't connect to hostapd when wpa(2) is enabled

Hi All,

I'm trying to setup hostapd by following this guide: http://wireless.kernel.org/en/users/Documentation/hostapd
When i use it as an open AP it works and the client is able to connect and receives an IP address from the running dhcp server. However, when i enable wpa and/or wpa2 it doesn't work at all.

My hardware is a virtualbox instance with a USB Wifi adapter:
Bus 001 Device 006: ID 050d:11f2 Belkin Components ISY Wireless Micro Adapter IWL 2000 [RTL8188CUS]

My current configuration is:

3 weeks, more than 180 reads and nobody is able to help ?

Just to be sure i'm bumping it to give it a second chance.

Thanks in advance for any help or suggestion.

This is my personnal configuration. country_code=CA and some other options should be change for your country and needs. I use channel=2. I am alone using this channel. I do not interfere with other access points in the wireless network neighborhood.

In /etc/hostapd/hostapd.accept, only the MAC address of allowed wireless cards are listed. In /etc/hostapd/hostapd.deny, I have nothing. Everything work without problem.

Note that the kernel of the access point must forward the packets and the firewall must make the NAT.

/etc/hostapd/hostapd.conf:

Thanks for sharing your configuration. Unfortunately it didn't work out for me. It seems stuck in the same way as with my first post, it seems the AP doesn't receive a response in phase 1/4 of the setup. The client (a phone) just tells me that the passphase was incorrect and offers me to try again. I've set the passphrase to something as easy as possible to avoid typos on the phone so i'm quite sure i entered it correct.

Do you have any suggestions to troubleshoot this ?

From what I can see the rtl8188cus uses the rtl8192cu driver. I have some usb rtl8192cu devices I tried both on client machines and with hostapd on the server. Won't put in print what I think of them.

I think last time I looked at them was around kernel 3.8. On the clients they could not maintain a connection to the ap. When I tried a rtl8192cu with hostapd then clients had trouble connecting and if they did manage to connect the connection dropped out shortly after. A work around that worked for some people was load the rtl8192cu module with the option swenc=1 to force encryption to be done in software. That did not work for me. I have been using usb wna110 and rt5370 devices since.

You having trouble with encryption where unencrypted worked reminded me of this.

Thanks for your suggestion Aiken, you are indeed right about the driver.

Since i usually don't use modules i provided the parameter on the kernel commandline, but that didn't work. After that i recompiled the kernel to use modules and loaded the rtl8192 module with the swenc=1 parameter, but that also didn't change the behavior.

You should try to connect as client with your Belkin wireless card who use the rtl8192 module for wlan0. If it can connect to an AP or in Haddoc mode and work, the problem can come the fact that the card cannot act as an Access Point. Did you check in the Supported interface modes if wlan0 can act as an AP when you do

I'm quite sure it supports AP mode, because that's why i started experimenting with hostapd

I think this is confirmed because it works as an open AP without encryption.
But to be sure: The "iw list" command shows IBSS, managed, AP, AP/VLAN, monitor, P2P-client and P2P-GO as supported interface modes.

Before i started experimenting with hostapd i used it for my daily work and everything worked as expected, so i'm sure the hardware is ok.
