Our verdict

Many routers, ONTs and switches recover from a bad flash by fetching firmware over TFTP, and Tftpd64 is the free Windows tool technicians use for it. It bundles a TFTP server and client with DHCP, DNS, SNTP and Syslog servers, and can run as a Windows service. tftpd64.com redirects to the project's GitHub page, but that page's quick link still points to an older version — take the current release (4.74, which added files larger than 4 GB) from GitHub Releases. Installer, portable and service builds are available, plus 32-bit Tftpd32.

FAQ

How do I use Tftpd64 to recover a router?

Follow your router maker's recovery guide: it will say which static IP to give the PC and what to name the firmware file. Put the file in Tftpd64's folder, select the right network interface, allow Tftpd64 through Windows Firewall, then start the router in recovery mode.
