Bad communication

[Tomislav Parčina]

Hi list!

I have installed hostapd and it's running. Now when I associate
Windows XP laptop to the hostapd AP they can't communicate. I still
haven't setup the DHCP server on hostapd, so I have setup IP addresses
manually. When I try to ping hostapd wireless NIC this is what I see
with tcpdump on hostapd:

10:15:49.240549 ARP, Request who-has 10.21.156.1 tell 10.21.156.11, length 28
10:15:49.240565 ARP, Request who-has 10.21.156.1 tell 10.21.156.11, length 28
10:15:49.240571 ARP, Reply 10.21.156.1 is-at 00:24:01:d3:bc:11 (oui
Unknown), length 28
10:15:54.741391 ARP, Request who-has 10.21.156.1 tell 10.21.156.11, length 28
10:15:54.741407 ARP, Request who-has 10.21.156.1 tell 10.21.156.11, length 28
10:15:54.741413 ARP, Reply 10.21.156.1 is-at 00:24:01:d3:bc:11 (oui
Unknown), length 28

Problem is that Windows XP laptop doesn't receive any response on it's
ARP request (at least wireshark installed on Win XP laptop doesn't
show response).

So, as far as I see from hostpad, he sends ARP response, and as far as
I see from Win XP he doesn't get ARP response.

How to troubleshoot this? Where could be the problem?

Best regards!
