1) Download the file openwrt-ar71xx-generic-mynet-n600-squashfs-factory.bin
2) Configure your computers IP address to 192.168.1.10 and connect to a LAN port in the router.
3) Turn the router off.
4) Using a paperclip, press and hold the reset button on the bottom of the router and turn it on. Hold the reset button for at least 15 seconds.
5) On your computer, visit http://192.168.1.1 NOTE: You will not be able to ping this address.
6) Upload the file openwrt-ar71xx-generic-mynet-n600-squashfs-factory.bin as downloaded earlier.
7) The router will now flash OpenWRT. This will take a couple of minutes to achieve. You can ping 192.168.1.1 and watch for ping replies to see when your router has rebooted into OpenWRT.
