[ath9k-devel] ath9k client/AP with Hostapd

["Lorna González"]

Hello, 

I am doing the same as in [ath9k-devel] ath9k as simultaneous AP/client but using wiphys. I am working with Linux kernel 2.6.34 and an atheros AR298x. Running hostapd works fine with the small test: 

interface=wlan1
driver=nl80211

hw_mode=g
channel=1
ssid=test

wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
wpa_passphrase=12345678

After I try to connect a station to the "test" AP, I got following: 

Mode: IEEE 802.11g  Channel: 1  Frequency: 2412 MHz

Using interface wlan1 with hwaddr 02:22:43:21:82:ac and ssid 'test'

But after this the station can not longer communicate to the AP. 
Has someone an idea of what is missing??

thanks in advanced

[ath9k-devel] ath9k client/AP with Hostapd

["Lorna González"]

Hallo, 

Thanks for your response Re: ath9k-devel Digest, Vol 27, Issue 8 (linux_pro).  But I still can find the problem in my test.

1.I build a virtual wiphy wlan1 using add wiphy and thus the MAC address is created by the driver through virtual.c. wlan0 hat the 00:22:43:21:82:ac MAC address and wlan1 02:22:43:21:82:ac. Therefore they differentiate just in one bit, like it is mentioned in the Digest. Vol. 27 Message 5. 

2. wlan0 is connected to an AP and works fine.
  
3. wlan1 is set to master using Hostapd creating an AP Test (Since I am working with wiphys I can use different channels).

4. Another station, working on Windows XP (no wpa_supplicant is necessary)  is trying to connect to AP Test. Authentication and Association with WPA2  seems to work fine since I get STA 00:12:f0:b2:1b:0f WPA: pairwise key handshake completed (RSN).  But after that there is no really a communication between AP test und the station. 
I read this http://www.su-root.eu/computing/turn-your-linux-computer-in-a-wireless-access-point-using-hostapd and use the bridge br0 but then no association is done.

I appreciate again your comments

Regards

Lorna
