mesh between AR5008 and AR5212

[paranormal]

Today I was trying what mesh is.

I have ap (stable) atheros 5008  and my laptop (stable) atheros 5212.

Following instruction https://wiki.freebsd.org/WifiMesh


both hosts have in rc.conf:
ifconfig_wlan0="inet 192.168.11.1 netmask 255.255.255.240 meshid mybsd
channel 3"

both sta was ESTAB.

The problem was:
After some time I was going mad. 
From my ap I can ping my notebook (after hard coding arp), and tcpdump
running on my notebook show my echo-request packets, but my laptop was
dumb. Ping from my notebook never ran, ping command ran but without
packets... 

The same situation with arp. Laptop got ap's arp, but ap never received
arp from my laptop.

Any idea?
