Hey! We’ll pinpoint why your eero has random shutdowns (or random reboots) and get your mesh stable again. “Shutdown” can mean a few different things, so I’ll ask a couple quick questions to avoid guesswork and get you the right fix fast:

• Which model(s): eero 6, eero 6 Pro, eero Pro 6E, eero Max, etc.? Is it only one node or the whole eero mesh Wi-Fi?
• What do you see when it happens: LED goes off, turns red, blinks, or does it go white again after 1–3 minutes like a reboot cycle?
• Is the gateway eero (the one connected to the modem) the one “restarting,” or a satellite node across the house?
• How is the gateway connected: directly to modem/ONT, through a switch, or through another router?
• Where is the eero placed: inside a cabinet, near a TV/console, stacked on other devices (possible overheating / poor ventilation)?

Give me those details and we’ll follow an expert troubleshooting checklist: power/heat first, then firmware and modem/ISP, then wiring/topology.

Thanks — that pattern (LED off → returns, sometimes red) is consistent with either power/overheating causing an eero reboot or the gateway losing upstream internet and briefly showing a red LED while it can’t reach the modem/ISP.

The big “repeat offenders” behind eero random shutdowns are:
• Power: loose power cable, flaky outlet, bad surge protector/UPS, power adapter intermittently dropping voltage.
• Heat: eero runs warm by design, but tight spaces, stacked devices, or dust can push it into thermal protection → random reboots or shutdown-like behavior.
• Modem/ISP: short ISP drops, DHCP lease renewals, signal noise; eero then goes red/offline and may appear to “restart.”
• Firmware / auto updates: a scheduled update can look like a reboot (usually once, not multiple times a day).
• Wiring/topology: bad Ethernet cable, switch loop, double-NAT/router conflicts can cause repeated instability at the gateway.

We’ll fix this in a step-by-step order that usually stops the shutdowns within 10–20 minutes.

Great clues — shelf near TV gear + surge protector + “runs warm” is exactly where eero Pro random restarts tend to show up. Let’s knock out the two fastest and most common fixes: stable power and ventilation.

Step 1 — Eliminate power interruptions (surge strip test)
1) Plug the gateway eero directly into a wall outlet for testing (bypass surge protector/UPS).
2) Ensure the power connector is snug on both ends — no wiggle.
3) If you have another compatible eero power adapter (same model family), swap it for a day to rule out a weak adapter (a failing adapter can cause random shutdowns that look like reboots).

Step 2 — Reduce overheating / thermal resets
1) Move the gateway eero to an open-air spot (not behind the TV, not in a cabinet).
2) Don’t stack anything on it; keep a few inches of clearance around it.
3) If the shelf is tight, even raising it slightly or moving it away from the soundbar can improve airflow.

After you do that, watch for 30–60 minutes. If the random reboots stop, we found the root cause. If they continue, we’ll check modem/ISP + wiring next.

Awesome question — distinguishing “ISP outage” from “device reboot” is the fastest way to stop chasing the wrong thing.

Step 3 — Identify whether it’s an ISP drop or an eero restart
Look for these clues when the network drops:
• If the eero LED turns red (or the app says “no internet”), that usually means the gateway can’t reach the internet — often modem/ISP, a bad Ethernet cable, or the modem is hung.
• If the eero LED goes off completely and then comes back like it’s booting, that’s more consistent with a power/thermal reset or a hard reboot.
• If only one satellite node drops but the gateway stays online, that’s more like mesh placement, backhaul interference, or a node-specific power issue.

Also check the eero service status page when things feel “random.” If there’s a rare service incident, you may see odd behavior across the app/cloud even though local Wi-Fi is fine.

Next we’ll do a clean restart flow (app restart) and then test the modem + Ethernet cable, because a flaky cable or switch can cause repeated gateway instability that looks like “random shutdowns.”

Red for a minute then back is often “upstream drop” — and yes, a weak Ethernet cable or a switch/topology issue can trigger it repeatedly.

Step 4 — Stabilize the gateway path (modem ↔ gateway)
1) Replace the modem-to-eero Ethernet cable with a known-good cable (Cat5e/Cat6). Even a tiny intermittent disconnect can make the gateway lose internet and look like a reboot.
2) For testing, connect like this: Modem/ONT → eero gateway → (optional) switch → everything else.
3) Temporarily bypass the switch for 30–60 minutes (plug only modem → gateway). If shutdowns stop, the switch/cable path is the culprit.

Step 5 — Correct reboot order (fixes modem handshake issues)
If you get repeated red LED / “no internet,” do this sequence once:
1) Unplug modem power for 60 seconds.
2) Unplug the gateway eero for 30 seconds.
3) Plug modem back in and wait until it’s fully online (lights stable).
4) Plug the gateway eero back in and wait for it to come online (white).

This clears “hung modem,” DHCP handshake, and WAN negotiation issues that can cause eero keeps going offline events several times per day.

Yes — firmware updates can look like a reboot, but they’re usually occasional (not repeatedly throughout the day). Still, we should confirm your network is healthy and up to date so it doesn’t fall into a reboot loop.

Step 6 — Check for firmware/app-related causes
1) In the eero app, confirm the network is fully online and check for any alerts. If a firmware update is pending, install it when you can tolerate a brief downtime.
2) Use the app’s built-in restart (clean restart): Home tab → tap the eero → menu (three dots) → Restart. This is safer than pulling power and can clear a stuck state that causes random eero reboots.
3) If the network drops at the same time daily, it can be a scheduled maintenance/update window or an ISP DHCP lease timing issue — we can correlate the timestamp and decide whether it’s “normal update behavior” or a real fault.

If you still see multiple random shutdowns after power/heat/cable fixes, then the next suspects are: (a) modem instability (ISP line), (b) a topology loop, or (c) failing hardware on the gateway unit.

Yep — wiring/topology can absolutely cause “random offline/reboot” symptoms, especially if the gateway is fighting an unstable Ethernet path.

What a topology loop looks like (and why it breaks eero)
A loop happens when the network has two active paths that feed back into each other (for example: gateway eero → switch → another eero → back to the gateway through a second cable). Unmanaged switches can’t always prevent broadcast storms. The result can look like:
• sudden network freezes
• eero app showing “offline/online” flapping
• devices disconnecting, gateway going red, or repeated restarts as the network collapses

Step 7 — Quick topology sanity check
1) Ensure there is only one “upstream” path: Modem/ONT → gateway eero is the only device touching the modem.
2) If you use Ethernet backhaul, wire it as: gateway eero → switch → wired clients and/or other eeros. Avoid wiring a satellite eero to two different switches/paths at once.
3) If your ISP modem is actually a modem/router combo, consider putting it in bridge mode (or disable its Wi-Fi/router features) to avoid double-NAT conflicts that can cause instability.

If you tell me how many switches and where the Ethernet cables go, we can map it quickly and eliminate loop risk.

Perfect wiring plan — that removes 90% of topology issues. If you still get eero random shutdowns after stabilizing power, ventilation, and the modem-to-gateway path, here’s the safe last-resort ladder (least disruptive → most disruptive):

Step 8 — Last resort troubleshooting
1) Use the eero app to restart only the gateway and see if it stabilizes for 24 hours (sometimes a stuck state causes repeated flapping).
2) If you have a spare eero, swap which unit is the gateway (use another node as the gateway). If the problem follows the original unit, that’s a strong sign of failing hardware or a bad power adapter for that specific eero.
3) Reset only if necessary: a soft reset can refresh configuration without fully wiping everything. A full factory reset is the final step if the config is corrupted — we typically only do this once we’ve proven power/heat/cables/modem are not the cause.
4) If the eero consistently goes red at the same times, contact your ISP and ask them to check the line for brief drops or signal issues. Short outages can look like “random restarts,” but the root cause is upstream.

If you want, open the chat and we’ll tailor the exact step (restart vs soft reset vs swap gateway) based on what the LED/app shows at the moment of failure.

Awesome — that’s exactly the outcome we want. Summary: for eero random shutdowns, start with stable power (wall outlet, tight connector), reduce overheating (open airflow), and make the gateway path clean (good Ethernet cable, modem → gateway, then gateway → switch). If you still see drops, check for ISP outages/red LED behavior, firmware updates, and wiring/topology loops. Want to confirm your layout or diagnose a stubborn reboot loop?
