- LEDs: 2x yellow/blue. Programmable (labelled as power on case) -
Non-programmable (shows WAN activity)
- Button: Reset
How to install:
1- Use OpenWRTInvasion to gain telnet and ftp access.
2- Push openwrt firmware to /tmp/ using ftp.
3- Connect to router using telnet. (IP: 192.168.31.1 - Username: root - No

4- Use command "mtd -r write /tmp/firmware.bin OS1" to flash into the router..
5- It takes around 2 minutes. After that router will restart itself to OpenWrt.
