Hello again Ganbold,

This time I can reproduce the problem on my computer. Please try attached patch. (patch to if_run.c) I suppose arp is for during dhcp negotiation. So, client does associate but cannot get IP address.

The device won't talk with other devices until 2-way handshake has happens. I thought it happens after 4-way handshake, but hostapd with -d option shows it happens several minutes later. I added code to set some registers ahead of it. So, no need to wait renegotiation happens.
