A guided TFTP Server recovery tool for macOS
Set a manual Ethernet IP on your Mac so it can talk to a router waiting at 192.168.1.1 during recovery. This is a recovery-prep step, not a guarantee that the router will accept firmware.
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.
It is in the same 192.168.1.0/24 subnet as 192.168.1.1, so the Mac can communicate with the router recovery address while avoiding a direct IP conflict.
OpenWrt-style failsafe and recovery workflows commonly use 192.168.1.1. Other brands and bootloaders may use different addresses, so check the model instructions first.
Recovery should use the Ethernet adapter connected to the router. If Wi-Fi remains active, the Mac may send traffic through the wrong interface and the router may never reach the TFTP Server.
Go to System Settings, Network, select Ethernet, open Details, then TCP/IP. Set Configure IPv4 to Manually and enter the IP address and subnet mask requested by your recovery guide.
For 192.168.1.254, use 255.255.255.0. Gateway and DNS are usually unnecessary for a direct recovery connection because the Mac only needs to reach the router locally.
After setting the Mac IP, confirm the firmware file, served folder, firewall permission, and recovery mode instructions. Then start the TFTP recovery check before powering the router into recovery mode.
After recovery, return the Ethernet adapter to DHCP or your normal network profile so your Mac can get an address from your regular router again.
Do not set the Mac to the same IP as the router. Avoid Wi-Fi for recovery when Ethernet is required. Confirm the active adapter is the one connected to the router.
Most recovery workflows expect Ethernet. Use a direct cable unless your device documentation says otherwise.
It is usually not needed for direct TFTP recovery. The local subnet route is what matters.
Follow the guide for your router. 192.168.1.254 is only for workflows where the router uses 192.168.1.1.
