Intro: Why this guide matters

If your Starlink keeps rebooting—Wi‑Fi dropping every few minutes, router lights flashing, the app showing "Offline" or "Searching for Satellites"—you’re seeing a common, but solvable, problem. This guide expands on proven fixes from real installation experience and gives you a full troubleshooting tree, firmware and power diagnostics, obstruction analysis, and clear guidance on when to call a professional.

Recognize the common symptoms

Before you troubleshoot, confirm the behavior. Typical symptoms of a reboot loop include:

Wi‑Fi disconnects every 5–10 minutes and returns after a reboot
The Starlink app frequently shows "Offline" or loss of satellites
The dish repositions or restarts itself
Router or PoE adapter lights flash and the unit powers down
Smart devices (cameras, TVs) repeatedly lose and regain connection

Quick checklist (do this first)

Run these quick isolation steps before digging deeper. They’ll identify the majority of issues in under 15 minutes.

Power: Plug the Starlink power supply directly into a different wall outlet (no surge protectors or extension cords).
Network: Temporarily disconnect all third‑party routers, switches, or PoE injectors—run Starlink as a standalone system.
Ethernet Adapter: If you use a Starlink Ethernet Adapter (Gen 2) or third‑party adapter, unplug it and test without it.
App: Open the Starlink app and note the firmware version and recent disconnect timestamps.

Full troubleshooting tree (stepwise isolation)

Work top to bottom. Each step either resolves the problem or tells you where to look next.

Step 1 — Power isolation
- Unplug Starlink from the outlet and plug into a different, dedicated wall socket.
- Remove power strips, UPS units, or long extension cords. Test for stability for 20–30 minutes.
- If rebooting stops, replace the power strip/UPS or have that circuit inspected.
Step 2 — Remove network variables
- Disconnect any third‑party router, switch, PoE injector, or Ethernet adapter. Use only the Starlink dish + router package.
- If the system stabilizes, add one network device at a time until the reboot recurs—this identifies the conflicting hardware.
Step 3 — Test Ethernet adapter compatibility
- Many reboot loops are triggered by incompatible PoE or passive PoE devices paired with the Starlink Ethernet Adapter or older Gen‑2 kits. Remove the adapter and test.
- Use the official Starlink adapter or a vetted, compatible injector when external routing is required.
Step 4 — Obstruction and signal check
- Use the Starlink app obstruction tool. Take screenshots of the red/yellow/green zones as evidence.
- Scan for moving obstructions (trees in wind), seasonal foliage, or reflective surfaces that may intermittently block signal.
Step 5 — Firmware and software
- Let the dish run uninterrupted for 30–60 minutes so it can receive updates. The app shows firmware status under Settings → Advanced → Firmware Version.
- If frequent reboots prevent an update, perform a factory reset (six plug cycles) to force a firmware recheck, then allow an uninterrupted update window.
Step 6 — Logs, patterns, and escalation
- Document reboot times, LED patterns, app messages, and any recent environmental events (storms, power outages, construction).
- If you’ve isolated hardware or confirmed persistent power faults, schedule professional diagnostics or contact Starlink support with your logs and device serial.

Deep dive: Firmware issues and what to do

Firmware bugs can cause repeated reboots; observed behaviors include watchdog resets, incomplete updates that leave the unit unstable, or firmware that doesn’t play nicely with third‑party hardware. Key points:

Starlink devices typically auto‑update when they have a continuous internet connection. Interruptions during updates can cause instability.
If frequent reboots keep interrupting updates, leave the system powered and connected for at least 30–60 minutes. Monitor the app for a change in firmware version.
Use the six plug‑cycle factory reset to force a firmware recheck if normal updates fail. This erases custom settings and returns the system to default operation.
If the router reboots immediately after a firmware update, capture the firmware version and timestamps, then contact Starlink support or your installer for escalation—do not attempt to load unofficial firmware.

Power supply problems: Symptoms and fixes

Power-related issues are among the most common causes of reboot loops. Symptoms that point to power problems include warm or hot power bricks, inconsistent uptime based on household loads, or reboots during peak electrical activity (e.g., when a microwave or HVAC turns on).

Always plug the Starlink power supply directly into a grounded wall outlet. Avoid surge protectors and long extension cords during troubleshooting.
Swap outlets to see if the issue follows the outlet or stays with the Starlink unit. If it follows the outlet, call an electrician to check the circuit and grounding.
Do not open the Starlink power brick. If it smells of burning, is bulging, or gets unusually hot, discontinue use and replace via Starlink or your installer.
For installations on remote sites or RVs, use a properly rated inverter or DC power kit designed for Starlink and confirm voltage stability under load.

Obstruction analysis: Why intermittent line‑of‑sight causes reboots

Starlink requires a clear view of the sky. If the dish continually loses satellites, it may go through reposition cycles and in some instances trigger system resets. Obstruction causes include:

Trees that sway and intermittently block the sky path, especially at certain elevations
Seasonal foliage changes or new construction nearby
Snow, ice, or heavy bird droppings on the dish surface
Roof mounts with insufficient elevation or nearby parapets

Use the Starlink app obstruction tool and perform a visual sweep at different times of day. If obstructions are confirmed, consider elevating the dish on a pole or relocating to a more open site. For permanent fixes, use a professional mount and pole sized to local wind and load requirements.

When to call a professional

Many users will resolve reboot loops with the steps above. Call an experienced installer when one or more of the following applies:

You’ve isolated the problem to power or grounding but don’t have electrical expertise
Reboots continue after removing third‑party network gear and the Ethernet adapter
Roof or pole access is required to relocate or re‑mount the dish safely
Your setup integrates with enterprise networks, VLANs, static WAN IPs, or fleet/remote site infrastructure
You require rapid resolution (same‑week scheduling) for business continuity

Professional technicians bring ladder safety, roof anchors, cable management, and tested replacement parts. They also run extended diagnostics (multimeter checks, replacement of suspect power supplies, cable continuity tests, and controlled firmware update windows) that are difficult to perform safely as a homeowner.

Practical tips and tools to have on hand

Smartphone with the Starlink app and the ability to capture screenshots of the obstruction tool and firmware screen
Short, heavy‑gauge outlet extension (for testing only) and a different wall outlet
Replacement OEM power brick or verified compatible power supply if you suspect the brick is failing
Labeling/tagging tools for cables so you can reconnect devices exactly the same way after testing
Basic ladder and safety gear if you must access roof mounts; otherwise call a pro

FAQ

Why did my Starlink start rebooting after a power outage?

Power outages can leave hardware in an inconsistent state. If a firmware update was interrupted or the power brick experienced a surge on restart, the unit may repeatedly attempt recovery cycles. Start by plugging Starlink into a different outlet, allow an extended update window (30–60 minutes), and if instability continues, consider a factory reset and professional diagnostics.

Can firmware really cause constant reboots?

Yes. A buggy or partially applied firmware update can leave the device unstable and cause watchdog resets. Because firmware installs require uninterrupted connectivity, recurring reboots can prevent updates from completing. Let the unit run continuously, use the app to confirm firmware status, and perform a factory reset only after other isolation steps.

Is my Ethernet adapter likely to be the problem?

Often. Incompatible PoE injectors, third‑party Ethernet adapters, or miswired cabling can create power draw or signaling issues that trigger reboots—this is especially common with Gen‑2 hardware. Remove the adapter and test. If stability returns, replace the adapter with the official Starlink adapter or a supported, tested model.

Can weather or wind make Starlink reboot repeatedly?

Extreme weather can cause temporary outages or physical movement of the dish, which may create repeated reconnection attempts. Snow and ice, heavy rain, or strong wind loads on a poorly secured mount can contribute to instability. Ensure mounts are rated for local conditions and clear the dish of debris or ice when safe to do so.

When should I replace hardware instead of repairing?

Replace hardware when physical damage is evident (burning smell, bulging power brick), when repeated failures have been traced to a single component (adapter, power supply), or when the device is out of warranty and intermittent faults continue despite testing. InstallPros can advise whether repair, replacement, or warranty RMA is the best path.
