IMPORTANT:
Notes for Linksys Routers: 
   be sure you have set boot_wait to yes. Power on your router
   after executing this script.
   Use openwrt-gs-code.bin or openwrt-g-code.bin as firmware.
 
Notes for Asus Routers:
   be sure POWER led is flashing (If this is not a case
   poweroff the device, push the reset button & power on
   it again, then release button)
   Use openwrt-linux.trx as firmware.

1) connect your pc to the LAN port
2) be sure your link is up and has an address in the
   192.168.1.0/24 address range (and not the 192.168.1.1)
