1. Reset Yun to factory default by:

reset-to-factory-anyway
reboot

( backup your own data )

2. Setup WIFI STA mode:

STA for managed (client) mode

3. SSH to wifi ip address:

nano setwanstaticip.sh

#!/bin/ash
uci set network.wan.proto=static
uci set network.wan.ipaddr=192.168.241.1
uci set network.wan.netmask=255.255.255.0
uci commit network
/etc/init.d/network restart

root@Arduino:~# /bin/ash setwanstaticip.sh
Successfully initialized wpa_supplicant
root@Arduino:~#

4.Setup 192.168.241.2 at PC

5.Entering http://192.168.241.1/ goto firewall setting edit both zone.

Make sure lan to wan, wan to lan forwardings and masquerading enabled.
