Why 192.168.1.254 is used
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.

How to Set Mac IP to 192.168.1.254 for Router Recovery
Set a manual Ethernet IP on your Mac so it can talk to a router waiting at 192.168.1.1 during recovery.
Quick answer
- Open System Settings, then Network.
- Select the Ethernet adapter connected to the router.
- Change IPv4 configuration to manual.
- Use IP address 192.168.1.254 and subnet mask 255.255.255.0 when your router recovery IP is 192.168.1.1.
- Switch back to DHCP after recovery.
Why the router may use 192.168.1.1
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.
How to set a static IP on macOS
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.
Subnet mask and gateway settings
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.
How to switch back to DHCP
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.
Common mistakes
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.
Final recovery checklist
Router is in recovery mode
Mac IP is set correctly
Firmware file is in the TFTP root
File name matches device requirement
Firewall is not blocking TFTP
Ethernet cable is connected to the correct port
Risk note:
Router recovery depends on your device model, firmware file, and bootloader recovery mode. This app helps prepare the TFTP recovery environment.
FAQ
Can I use Wi-Fi instead of Ethernet?
Most recovery workflows expect Ethernet. Use a direct cable unless your device documentation says otherwise.
Should the gateway be 192.168.1.1?
It is usually not needed for direct TFTP recovery. The local subnet route is what matters.
What if my guide says 192.168.0.66?
Follow the guide for your router. 192.168.1.254 is only for workflows where the router uses 192.168.1.1.
