| Keep in mid that one battle is over, but this is not the end of the warWe won this factory reset battle but the war is over. After having restored the genuine official vendor image, we need to re-install OpenWRT with the latest 19.07.4 image and configure OpenWRT so that it can acts as a "dummy Wifi Access Point". DHCP, DNS will be served by the SOHO router. |

- We presented freeRouter TFTP embedded server
- You can use it in order to undertake network equipment deployment requiring TFTP
- This TFTP server is compatible with IPv4/IPv6
TFTP is a basic but a common tool in SP environment (or it was? If it is still used, yes please confirm !) In this example, I demonstrated the use of TFTP server in order to flash a wifi router to factory default. I have 802.11ac back up and running !
