MAC STATIC IP · RECOVERY SETUP
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.
Use 192.168.1.254 on Mac Ethernet only when the exact model guide says the router recovery address is 192.168.1.1.
CONFIRM THE CONDITIONS BEFORE CHANGING NETWORK
Confirm the router recovery IP, subnet, and active Ethernet adapter first. If the guide requires 192.168.0.66, 192.168.1.10, or another address, follow the model guide.
This is a preparation checklist, not live device detection.
Green items can be prepared on the Mac; amber or red items require verification first.
QUICK ANSWER
MAC NETWORK SETUP
Do not change Wi-Fi or an unrelated interface. Record the original setting and restore DHCP immediately after recovery.
Verify that the router recovery address is 192.168.1.1 rather than another subnet or vendor-specific method.
In System Settings → Network, choose the Ethernet or USB Ethernet adapter directly connected to the router.
Set IPv4 to Manually, enter 192.168.1.254 and 255.255.255.0, and usually leave gateway and DNS empty.
After recovery, return that interface to DHCP or restore its previous network profile.
PLAIN-LANGUAGE TERMS
A manually assigned address that stays fixed during the brief recovery session.
The Mac and router share the same first three address groups with a 255.255.255.0 mask, while keeping different full IP addresses.
The value that tells macOS which addresses are reachable directly on the local Ethernet link.
The normal automatic address setting to restore after the recovery attempt.
MACOS STEPS AND VERIFICATION
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.
FINAL CHECK
MACOS RECOVERY NETWORK
Router Recovery helps verify Ethernet, firmware, the served folder, and the local TFTP waiting state.
FAQ
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.
