These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Firmware reload guided by NETGEAR
What they doNETGEAR support guides you through uploading the official firmware again over TFTP from a computer connected to the router by cable.
They must show youthe correct firmware version for your model and the LED ending solid white or green.
In writingthe case number, the firmware version and the date.
Warranty assessment
What they doIf the router still does not boot after the firmware reload, NETGEAR support assesses whether the unit should be repaired or replaced.
They must show youthe result of each step and the proof of purchase.

Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Full network power cycle in order
- Who:
- you.
- How:
- turn off the modem, the router and the other devices, wait 2 minutes, turn on the modem first and wait about 5 minutes; then turn on the router and wait several minutes without touching it.
- Result that matters:
- the Power LED staying solid white or green.
- If it goes solid:
- the router booted; check the firmware version when you log in.
- If it keeps blinking white:
- check the adapter and cables.
- Evidence to keep:
- note of the time and the final LED state.

Original adapter and no Ethernet cables
- Who:
- you.
- How:
- use only the adapter that came with the router, plugged straight into the wall, unplug every Ethernet cable and restart the router again.
- Result that matters:
- ruling out that power or a connected device stops the boot.
- If it boots:
- reconnect the cables one at a time.
- If it keeps blinking white:
- the firmware probably needs reloading.
- Evidence to keep:
- note of the adapter and what was connected.

Check the model before reloading firmware
- Who:
- you.
- How:

- Result that matters:
- having the correct official firmware file for your model.
- If you find the firmware:
- follow NETGEAR's TFTP guide only if you understand every step.
- If you are unsure about the model or the file:
- contact NETGEAR support.
- Evidence to keep:
- photo of the label and the name of the downloaded file.

What it means
In NETGEAR's official LED guide (Nighthawk R7000, RAX50, XR500 and others), a blinking white Power LED means the router's firmware is corrupted; solid white or green means it is ready. NETGEAR explains that a failed update or a power outage can corrupt the firmware and suggests reloading it over TFTP from a computer connected by cable. On the R8000, alternating white and amber means AP mode, not a fault. The LED alone never proves the router is faulty.
