A guided TFTP Server recovery tool for macOS
Use this page when your router guide says the computer should provide a firmware file by TFTP. Before another power cycle, prepare the Mac side first: Ethernet, static IP, firmware filename, served folder, firewall, and recovery timing.
TFTP: a simple local file-transfer method. In recovery, the router may ask your Mac for one firmware file.
Recovery mode: a temporary rescue state used when the router cannot start normally. It usually exposes only the basics needed to accept firmware.
Bootloader: the small startup program that runs before the normal router system. Many recovery flows are controlled by it.
Static IP / same subnet: a temporary Mac address such as 192.168.1.254 so the Mac can talk to a router waiting in recovery mode.
What to do: check the router label and hardware revision, then download matching recovery firmware. Why: mismatched firmware is a common cause of failed recovery. You should see: a filename, model, and hardware revision that clearly match.
What to do: temporarily set the Mac Ethernet IP to the address required by the guide, such as 192.168.1.254. Why: this lets the Mac communicate with the router while it is in recovery mode. You should see: Ethernet connected, with the Mac IP and router recovery IP in the same local network range.
What to do: select the firmware file and let Router Recovery wait for the router request. Why: the router recovery window may be brief, so the Mac should be ready first. You should see: the app waiting for the router request or showing that a request was detected.
What to do: follow the model guide, usually power off, hold Reset or WPS, then power on. Why: the router must enter recovery mode before it can request or accept firmware. You should see: the documented LED pattern, a brief network response, or the app detecting a firmware request.
TFTP recovery is a local firmware transfer used by many router bootloaders. In the supported path, the router asks your Mac for a firmware file during a short startup recovery window.
Use this path only when your model guide says to run a TFTP Server or provide a firmware file from the computer. If the guide requires a vendor utility, NMRP, serial TTL, or hardware repair, treat that as a different recovery path.
Set the correct Ethernet IP, choose the firmware folder served by the app, and allow the app or TFTP traffic through the firewall before triggering recovery mode.
Some routers request a specific filename. Use the filename required by the model guide and avoid hidden archive extensions such as .bin.zip.
Start Router Recovery before the recovery window begins. If you start after the router has already given up, the transfer may time out.
If recovery fails, check the firmware folder served by the app, Ethernet adapter, firewall prompt, router IP, and whether another network service is using the wrong adapter.
No. It is usually a local Ethernet connection between your Mac and the router.
The router may not be in recovery mode, the Mac IP may be wrong, or the firmware file may not be in the served folder.
Most router recovery workflows expect Ethernet. Use a direct cable unless your model guide explicitly says otherwise.
No. Recovery depends on the router model, firmware file, bootloader behavior, and whether the device enters recovery mode. The app helps prepare and check the Mac TFTP Server environment.
