eero LUZ-ROJA on mesh router: the eero is not getting an Internet connection
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
A solid red light on an eero means it is offline: it is not receiving Internet. First check whether all your eeros are red or just one, because eero gives different steps for each case, and open the eero app to see its diagnosis.
Safety first
Stop and check this first
- Do not confuse solid red with flashing red: eero says flashing red means a reset is in progress, and you should not unplug the unit while it happens.
Safe checks you can perform
- How many eeros are red and what the app says
- Possible provider outage
- Restart the modem or ONT and the Primary eero
- Only one eero is red
Leave these tasks to a qualified professional
- Do not attempt this professional task: Line and modem or ONT check by the provider
- Do not attempt this professional task: eero Support for an eero that will not connect
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.
Line and modem or ONT check by the provider
What they doThe provider checks whether its modem or ONT is in service, whether the line has a fault, and which settings (VLAN, static IP, PPPoE) the router needs.
They must show youthe line and modem or ONT status.
In writingthe exact settings their service requires and the fault found.
eero Support for an eero that will not connect
What they doIf the cable and port work and one eero stays red, eero Support checks that unit.
In writingthe tests done and, if it is replaced, the reason.
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.
How many eeros are red and what the app says
- Who:
- you.
- How:
- look at all your eeros and open the eero app while connected to their network: Home shows Offline in red and an option to troubleshoot the connection.
- Result that matters:
- knowing whether the whole network or one eero is failing.
- If all are red:
- the problem is the provider connection; check the modem or ONT.
- If only one is red:
- check that eero and its link to the others.
- Evidence to keep:
- a screenshot of the app diagnosis.

Possible provider outage
- Who:
- you.
- How:
- check your Internet provider's website for an outage in your area.
- Result that matters:
- knowing whether the outage is general.
- If there is an outage:
- wait for the fix; eero lets you use Hotspot Backup with your phone meanwhile.
- If there is no outage:
- go on to restarting the modem or ONT.
- Evidence to keep:
- a screenshot of the service status with date and time.
Evidence: What should I do if my eero network is offline?
Restart the modem or ONT and the Primary eero
- Who:
- you.
- How:
- leave only the Ethernet cable to the Primary eero plugged into the modem, unplug the modem or ONT for at least 3 minutes, plug it back in and wait until it is online (eero says it can take 5 to 10 minutes). Then restart the Primary eero and wait for a solid white light.
- Result that matters:
- whether the Primary eero ends up solid white.
- If it is white:
- the WAN connection is back.
- If it stays red:
- try a different Ethernet cable and repeat; if nothing changes, contact your provider.
- Evidence to keep:
- times of each step and the final light colour.
Evidence: What should I do if my eero network is offline?
Only one eero is red
- Who:
- you.
- How:
- unplug that eero for 30 seconds and plug it back in. If it is wireless and red returns, move it closer to another eero. If it is wired, plug its cable into a laptop to see if the cable carries Internet, and try another cable or port.
- Result that matters:
- whether that eero returns to solid white.
- If it turns white after moving it or changing the cable:
- range or the cable was the cause.
- If the laptop has no Internet on that cable either:
- the cable, port or upstream connection is at fault.
- Evidence to keep:
- what you changed and the result of each test.

What it means
eero says a solid red light means offline: the eero is not receiving an Internet connection. If every eero is red, the upstream connection (modem, fibre ONT or provider service) is commonly not communicating with the Primary eero; eero calls this a WAN connection issue. If only one is red, the fault is usually in its link to the rest of the network. The light does not prove the eero is faulty.
Warnings and stop conditions
- Loweditorial warning
Do not confuse solid red with flashing red: eero says flashing red means a reset is in progress, and you should not unplug the unit while it happens.

Symptoms and causes
Probable causes · in order
- WAN connection or provider downCommon
All eeros red. It can be a provider outage, a stuck modem or ONT, or the Ethernet cable between modem and Primary eero.
Evidence: Why does my eero have a red LED? · What should I do if my eero network is offline?
- A wireless eero too far awayPossible
Only one eero red and connected wirelessly. Confirmed if it turns white when moved closer to another eero.
Evidence: Why does my eero have a red LED?
- Faulty Ethernet cable or portPossible
Only one wired eero red. Tell it apart by plugging the same cable into a laptop: if the laptop has no Internet either, the cable, port or connection is at fault.
Evidence: Why does my eero have a red LED?
- Provider settings the eero lacksPossible
Some providers need VLAN tagging, a static IP or PPPoE. Without them the app fails when confirming ISP settings.
Evidence: What should I do if my eero network is offline?
