OPENWRT TFTP RECOVERY · MACOS

OpenWrt TFTP Recovery Checklist for Mac

Use this checklist only when the exact device guide says the router bootloader will request firmware from a TFTP Server on your Mac. Confirm the transfer direction, recovery IP, firmware, filename, Ethernet port, and power-on sequence before retrying.

Use this page only when the exact model guide says the router requests firmware from a TFTP Server on the computer. If the router waits for an upload, the direction is different.

CONFIRM THE TFTP DIRECTION

The device guide must explicitly require a TFTP Server on the Mac

Recovery capability comes from the device bootloader, not from OpenWrt itself. Confirm the model, TFTP direction, IP, and filename before preparing the Mac.

OpenWrt TFTP Server readiness

This is a preparation checklist, not live device detection.

  • TFTP direction The router acts as client and requests firmware from the Mac Must confirm
  • Recovery network IP, subnet, and Ethernet port come from the exact model guide Confirm
  • Firmware and filename Image type, hardware revision, and requested filename must match Confirm
  • Mac TFTP Server Ethernet, served folder, and local firewall can be checked first Prepare

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

QUICK ANSWER

Start the recovery window only after four facts are confirmed

  • Confirm the exact model page documents bootloader TFTP recovery.
  • Confirm the router acts as a TFTP client and requests a file from the Mac.
  • Use the Mac IP, subnet, Ethernet port, and filename specified for that model.
  • Verify the image type and hardware revision before placing the file in the served folder.
  • Start the local TFTP Server check before triggering the brief recovery window.

RECOVERY PROCESS

Prepare Method, Firmware, Mac, then Request

This is not a universal OpenWrt flashing flow. First prove the device requests a file, then prepare the Mac to serve it.

  1. Step 1

    Method

    Check the exact device page for bootloader TFTP recovery and confirm the router is the side that requests the file.

  2. Step 2

    Firmware

    Verify the model, hardware revision, image type, checksum, and exact filename required by the bootloader.

  3. Step 3

    Mac

    Use direct Ethernet, set the required temporary static IP, and prepare the served folder and firewall.

  4. Step 4

    Request

    Finally follow the device-specific button and power sequence and observe whether it asks for the expected file.

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.

OPENWRT TFTP SERVER BOUNDARY

Separate device-specific facts from Mac-side preparation

1

Confirm that this is a TFTP Server workflow

OpenWrt documents two opposite bootloader patterns: some routers request firmware from a TFTP Server on the computer, while others expose a TFTP server and wait for a client upload. Router Recovery serves the first pattern. The exact device page must identify which direction applies.

2

Treat every recovery network value as model-specific

Do not assume 192.168.1.1 or 192.168.1.254. The bootloader may require another router address, Mac address, subnet, or Ethernet port. Copy those values from the exact hardware-revision instructions.

3

Use the image and filename the bootloader expects

Match the brand, model, hardware revision, region, and required recovery image type. If the guide specifies a request filename, use it exactly and check for hidden extensions. Renaming an incompatible image does not make it safe.

4

Prepare the Mac before powering on

Connect by Ethernet, set the documented temporary static IP, choose the served folder, allow only the needed local TFTP traffic, and start the recovery check before triggering the router.

5

Observe the request instead of guessing

A router-side file request is evidence that the TFTP Server path and recovery timing are active. No request points back to recovery mode, IP, interface, cable, port, firewall, or an incorrect recovery method.

6

Stop the local service when recovery ends

TFTP has no authentication. Keep it on the private recovery network, serve only the user-selected firmware, then stop the service and restore the normal Mac network and firewall settings.

FINAL CHECK

Final check before triggering recovery mode

  • 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

Prepare Mac-side TFTP only after confirming the router requests a file

Router Recovery helps check the temporary IP, Ethernet, firmware file, served folder, and local request-waiting state.

FAQ

OpenWrt TFTP Server recovery questions

Does every OpenWrt router support TFTP Server recovery?

No. Recovery support and transfer direction come from the device bootloader. Some models use Web recovery, a TFTP client upload, a vendor utility, or another method.

Does every OpenWrt recovery use 192.168.1.1 and Mac 192.168.1.254?

No. Use only the IP, subnet, Ethernet port, and filename documented for the exact model and hardware revision.

What proves that this TFTP Server path is active?

The router requests the expected filename from the Mac during its documented recovery window. If no request appears, recheck the method and recovery mode before changing files.

Does Router Recovery flash OpenWrt automatically?

No. It prepares and checks the local Mac TFTP Server environment. The device bootloader decides whether it requests and accepts firmware.
