I I finally found a way to back to openwrt(not wiibox orignal firmware).
willbox controller is Similar to GL.inet product.
1. go to failsafe mode : push reset button and power on until two led on(not blinking)
(read this :

2. use netconsole(nc.exe) to connect 192.168.1.1 (you can do this using serial to usb adapter)
3. type httpd
4. connect 192.168.1.1 by chrome browser(not IE)
5. upload firmware and flash(
http://www.gl-inet.com/firmware/v1/openwrt-gl-1.071.bin)
6. after reboot you can connect 192.168.8.1 by wifi and do initial setup
Ethernet port is Wan port.
If you want to connect Ethernet port, you have to open firewall by editing /etc/config/firewall.
LA Firmware is SUCKS!!!!
It doesn't work with many pool(waffle, nicehash, most single pool, etc)
Only work with some pool(ipominer, ghash/ltc, multipool.us, etc)
He don't offer revert method, open ssh, root password.
I think this firmware has to remove on open community!!!!!
Is there any way to install bfgminer on openwrt?
