Linksys LUZ-AMARILLA-FIJA on mesh router: weak child node signal
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
A solid yellow light on a Velop node means it is a wireless child node with a weak signal: it is connected but far from the node it links to. Linksys recommends moving it closer to another node until it turns blue.
Safety first
Stop and check this first
- With a yellow light the node still provides Wi-Fi, only slower: it is a placement warning, not a fault.
Safe checks you can perform
- Read the node signal in the app
- Move the node closer and clear its surroundings
- Boot the nodes in order
- Check the system firmware
Leave these tasks to a qualified professional
- Do not attempt this professional task: Open a case with Linksys support

What a technician must be able to justify
Technician visit
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.
Open a case with Linksys support
What they doIf the node stays yellow while close to a blue node, with the right boot order and current firmware, Linksys support reviews the mesh network.
They must show youthe signal of each node and which node each one connects to.
In writingthe case number, the diagnosis and whether any node is covered by warranty.
Ask Linksys about placement
What they doIf the layout of your home does not let you move the node closer, Linksys support can guide you on where to place each node in the chain.
They must show youthe signal value at the proposed location.
In writingthe case number and the recommended location for each node.
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.
Read the node signal in the app
- Who:
- you, with the Linksys app.
- How:
- go to Network Administration, Nodes, and tap the yellow node to see its Signal Strength; 0 to -50 dBm is excellent and -70 dBm or below is poor.
- Result that matters:
- knowing how far the node is from a good link.
- If the signal is poor:
- move it closer to another node.
- If the signal is acceptable:
- check for obstacles and which node it connects to.
- Evidence to keep:
- screenshot of the signal value before moving it.

Move the node closer and clear its surroundings
- Who:
- you.
- How:
- move the node closer to another blue node, within about two rooms or one floor, out in the open and away from metal, large glass panes and appliances such as the microwave.
- Result that matters:
- the light changing from yellow to solid blue.
- If it goes blue (about two minutes if you unplugged it):
- check the signal again.
- If it stays yellow:
- try the boot order Linksys suggests.
- Evidence to keep:
- new location and signal value after the change.

Boot the nodes in order
- Who:
- you.
- How:
- turn off all nodes, power the parent and wait for solid blue; then power each child in its place, one at a time and close to the previous one, waiting for blue before the next.
- Result that matters:
- each node linking to the nearest node in the chain rather than a distant one.
- If all stay blue:
- the mesh chain is set up correctly.
- If one node stays yellow:
- move it closer to the previous node in the chain.
- Evidence to keep:
- power on order and the colour of each node.

Check the system firmware
- Who:
- you, with the Linksys app or the web interface.
- How:
- look for updates under Network Administration in the app, or Connectivity, Basic in the web interface; an update also restarts the mesh network.
- Result that matters:
- ruling out connection faults that firmware fixes.
- If there was an update and afterwards the node stays blue:
- done.
- If it was already current and stays yellow:
- contact Linksys support.
- Evidence to keep:
- firmware version of each node.

What it means
In the official Linksys Intelligent Mesh light guide (WHW and MX series and MR routers), solid yellow means weak signal on a wireless child node, and on the MX5300, MX4000 and MX8500 it reads weak connection for child nodes only. The node works, but the Wi-Fi link to its upstream node is poor and speed drops. Linksys measures that signal as RSSI in the app. The light alone never proves the node is faulty.
Warnings and stop conditions

Symptoms and causes
Probable causes · in order
- Node too far from its upstream nodeCommon
Linksys says that if a child node light stays yellow, its connection to the upstream node is too weak and it should be moved closer.

- Obstacles between nodesPossible
Linksys advises against cabinets, behind a TV, large glass panes and metal objects such as fridges, fish tanks or microwaves.
Evidence: Mesh WiFi Connectivity FAQs
- Node linked to a distant unit in the chainPossible
Linksys explains the farthest node can stay attached to a distant parent node instead of a closer intermediate node.
