Atheros AR5414 PCI WDS point-to-point link with wpa-psk2 encryption

[Teh Kok How]

Hi;

            Greetings!

I am new with hostapd/wpa_supplicant. I am using Atheros AR5414 PCI card
with madwifi-trunk-r4100 driver stack running on an IXP-425 platform
(OpenWRT kamikaze-trunk, linux-2.6.32). The WDS link works fine without
encryption. In an effort to establish an 128/256-bit AES-encrypted link in
this WDS point-to-point setup, I run hostapd on the 2 target boards. However
all I could see in `tail -f /var/log/messages` is the EAP state machine
running. Although the TX/RX packets increase in the `ifconfig` output during
the `ping`, they are dropped somehow on the way up through the networking
stack.

            If anyone out there has successfully used hostapd in this WDS
point-to-point link setup with 128/256-bit AES encryption link, I would
appreciate any insight and advice given. Some details of my setup follows.

            Thanks.

 

Regards,

KH
