TFTP RECOVERY · MACOS

TFTP Recovery on Mac

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.

Run a TFTP Recovery Check View recovery checklist

Use this page when the exact model guide tells the computer to run a TFTP Server and the router requests firmware during recovery.

STABILIZE BEFORE RETRYING

Prepare four Mac-side conditions first

The router recovery window may last only seconds. Ethernet, temporary static IP, firmware, and local TFTP should be ready before power-on.

Mac TFTP recovery readiness

This is a preparation checklist, not live device detection.

  • Ethernet Connect the Mac directly to the router instead of relying on Wi-Fi Prepare
  • Mac static IP Use the address and subnet required by the model guide Confirm
  • Firmware and filename Put the exact image and required filename in the served folder Confirm
  • Recovery mode Follow the model-specific button and power timing Device step

Green items can be prepared on the Mac; amber or red items require verification first.

QUICK ANSWER

Finish these checks before another power cycle

  • Use Ethernet between the Mac and router; do not rely on Wi-Fi for recovery.
  • Set the Mac to the temporary manual IP required by the router guide.
  • Put the correct firmware file in the folder served by Router Recovery.
  • Use the exact filename required by the model when one is documented.
  • Start the recovery check before powering the router into recovery mode.

RECOVERY PROCESS

Prepare Network, Firmware, TFTP, then Recovery

Prepare the Mac first, then trigger the router. Do not wait until the recovery window opens to change IP, find firmware, or handle firewall access.

  1. Step 1

    Network

    Use direct Ethernet, remove unrelated network paths, and set the temporary static IP required by the model.

  2. Step 2

    Firmware

    Verify the exact model, hardware revision, image type, filename, and folder served by the App.

  3. Step 3

    TFTP

    Start the Router Recovery check and allow local TFTP traffic through the macOS firewall.

  4. Step 4

    Recovery

    Finally trigger model-specific recovery mode and observe the router request and transfer result.

PLAIN-LANGUAGE TERMS

Terms you will see during recovery

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 exposes only the basics needed to accept firmware.

Bootloader

The small startup program that runs before the normal router system and controls many recovery flows.

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.

MAC-SIDE PREPARATION

Every item should be verifiable before router power-on

1

What TFTP recovery means

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.

2

Confirm this page matches your router

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.

3

Prepare macOS before the router boots

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.

4

Choose the correct firmware name

Some routers request a specific filename. Use the filename required by the model guide and avoid hidden archive extensions such as .bin.zip.

5

Start the recovery check first

Start Router Recovery before the recovery window begins. If you start after the router has already given up, the transfer may time out.

6

Confirm the transfer path

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.

FINAL CHECK

Mac checklist before the recovery window

  • Router is in recovery mode
  • Mac IP is set correctly
  • Firmware is in the served folder
  • Filename matches the device requirement
  • Firewall is not blocking local TFTP
  • Ethernet is connected to the correct port

ROUTER RECOVERY · MACOS

Prepare the local TFTP recovery environment on Mac

Router Recovery helps check Ethernet, the temporary IP, firmware file, served folder, and recovery readiness before waiting for the router request.

FAQ

TFTP recovery on Mac questions

Does TFTP recovery need internet?

No. It is usually a local Ethernet connection between your Mac and the router.

Why does TFTP recovery time out?

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.

Can I use Wi-Fi for TFTP recovery?

Most router recovery workflows expect Ethernet. Use a direct cable unless your model guide explicitly says otherwise.

Does Router Recovery guarantee the router will recover?

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.
