A guided TFTP Server recovery tool for macOS
ASUS recovery should start with Rescue Mode, the exact model, official firmware, Ethernet, and a temporary Mac IP. Router Recovery 2.1 adds guided ASUS Rescue / TFTP checks for selected ASUS profiles, but upload completion is still not proof that the router has finished writing firmware.
TFTP: a simple local file-transfer method. In ASUS Rescue Mode, the Mac may actively send firmware to the router after the rescue response is confirmed.
ASUS Rescue Mode: a vendor recovery state used before the normal router firmware starts. It may accept official ASUS firmware through a rescue workflow.
Verified reference devices: devices where this workflow has the clearest evidence, currently RT-AC86U and RT-AX86U. This is not a broad supported-model list.
Static IP: a temporary Mac Ethernet address such as 192.168.1.10 with subnet mask 255.255.255.0 so the Mac can talk to the router at 192.168.1.1.
Many ASUS routers expose a rescue state before the normal firmware starts. The usual pattern is to set a temporary Mac IP, connect by Ethernet, hold the required button while powering on, and wait for the Rescue Mode signal before sending firmware.
Router Recovery 2.1 separates ASUS active TFTP from OpenWrt-style passive TFTP. For selected ASUS profiles, it can check whether the router returns the expected rescue response, then continue with guided firmware upload after unlock.
RT-AC86U and RT-AX86U are the clearest reference devices for this workflow. Other ASUS routers may use similar Rescue Mode behavior, but they should be treated as candidate paths until there is device-level evidence.
For the tested ASUS Rescue path, prepare Mac Ethernet as 192.168.1.10 with subnet mask 255.255.255.0, and leave Router/Gateway empty on that recovery interface. Keep another internet path such as Wi-Fi or hotspot only if needed for unlock or restore.
Choose official ASUS firmware for the exact model and region. Router Recovery accepts ASUS rescue firmware extensions such as .trx, .w, and .pkgtb in this flow, but the router still decides whether a file is valid.
Do not treat upload completion as recovery completion. The router may still be writing firmware and rebooting. Keep power connected, wait, return Mac Ethernet to DHCP, then verify the admin page and firmware version.
If the ASUS guide requires a browser recovery page, a vendor-only utility, serial access, or a different recovery address, follow that model-specific path instead of forcing a TFTP upload.
No. ASUS support is profile-driven. RT-AC86U and RT-AX86U are verified reference devices, while other ASUS models should be treated as candidate paths until verified.
No. ASUS Rescue / TFTP is an active TFTP upload workflow, while OpenWrt-style recovery often waits for the router to request a file from the Mac.
For the tested ASUS Rescue path, use 192.168.1.10 with subnet mask 255.255.255.0 when the router waits at 192.168.1.1. Follow your model guide if it gives a different value.
No. Upload completion only means the firmware file was sent. The router may still need time to write firmware, reboot, and return to the admin page.
