Some Starlink disconnections are fixable in under five minutes. Others are built into how the technology works and cannot be fully eliminated — only managed. Knowing which is which saves hours of frustration. This guide covers the actual causes, ranked by how often they’re responsible, and what to do about each one.
Before you climb on the roof, swap cables, or call support, read these. Most disconnection problems fall into one of a handful of causes — and half of them can be diagnosed from your phone without touching the hardware.
Yes — and it’s worth understanding why before assuming something is wrong. Starlink satellites orbit at about 550 kilometers above Earth and move across the sky at roughly 17,000 miles per hour. Your dish has to hand off its connection to a new satellite approximately every 15 seconds as one satellite passes out of range and the next one comes into view. Each of those handoffs carries a small risk of a brief dropout. Data tracked across 6,228 real-world Starlink dishes shows an average of about 33 minutes of disconnected time per day — roughly 2.3% of all connected time. Brief dropouts of a few seconds scattered through the day are not a sign your equipment is broken. Frequent, longer outages — or drops that follow a very regular rhythm — almost always point to a fixable cause.
Obstruction — something physically blocking part of the sky your dish needs to see. A tree branch, roofline, chimney, or even a swaying bush can clip the signal during satellite handoffs and cause brief but repeating dropouts. The important thing to understand: you don’t need to block much sky to cause serious connection problems. A single branch covering just 2% of the dish’s sky view can trigger 20 or more dropouts per day. Because the satellites are always moving, the obstruction might cause drops at 2:00 PM but not at 2:15 PM, making the problem feel random when it’s actually predictable. The Starlink app’s obstruction viewer shows you exactly where the problem is.
This is almost always an obstruction hitting during satellite handoffs. Starlink’s dish switches between satellites roughly every 4 minutes, and if a tree branch or chimney edge sits in the path of an incoming satellite during that handoff, you get a brief disconnection on that exact cycle. It feels maddening because of how regular it is — and because clear skies and perfect weather don’t fix it. Open the Starlink app, go to Visibility, and look at the obstruction map after letting it run for at least 12–24 hours (new installs need time to accumulate satellite-pass data before the map is useful). The red areas on that map are where your trouble is coming from.
Yes, and the research data is specific about how much. Peer-reviewed studies across multiple countries found that throughput drops by an average of 27% during any form of precipitation. Heavy rain — over 4mm per hour — can cause noticeable speed loss and brief disconnections. Thunderstorms cause 420% more frequent outages than clear-sky conditions. Light rain and clouds generally cause minor slowdowns but rarely full disconnections. Heavy snow can accumulate on the dish faster than its built-in heater can clear it, temporarily blocking the signal. The fix for weather drops is mainly dish placement — a dish that already has obstruction problems will perform significantly worse in bad weather than one with a clean sky view. Clear sky matters most when conditions are hardest.
Yes — the app reboot and the wall reboot are genuinely different. The Starlink app’s reboot button sends a software restart command to the router. It does not cut power and does not clear the same hardware states as physically unplugging from the wall. The correct power cycle: unplug the router from the wall outlet — not from the app — wait a full 30 seconds, then plug it back in and leave it alone for 5–10 minutes while the dish orients and reconnects. Many problems that survive dozens of app reboots clear up immediately after a proper wall unplug. The 30-second wait matters — capacitors in the unit need that time to fully discharge.
This is a different problem from a dish disconnection. When the app shows “Connected” but devices report no internet, the issue is between your router and your devices — not between the dish and the satellite. The most common causes: your device drifted onto a neighboring Wi-Fi network with the same or similar name; the router’s Wi-Fi radio got stuck; or there’s an IP address conflict on the network. First step: forget the Starlink Wi-Fi network on your device and reconnect from scratch. If that doesn’t work, do a full wall power cycle on the router. If it still doesn’t clear, a factory reset of the router is the next step — which wipes your network name and password, so do it last after ruling out the simpler causes.
Something probably did change, even if it wasn’t obvious. The most overlooked cause: seasonal foliage. A tree that posed no obstruction problem in winter, when branches were bare, can become a serious signal blocker in spring and summer once leaves fill in. A tree that was 10 feet tall two years ago may now reach the dish’s field of view. New construction nearby — a neighbor’s shed, an added roofline feature, a new fence — can appear in the dish’s sky cone without you noticing from ground level. Run the obstruction check in the Starlink app from the dish’s current location and compare it to clear sky. Also check whether a firmware update recently went out — these occasionally introduce temporary instability that resolves within 24–48 hours as the update propagates.
Absolutely — and it’s more common than people expect. The proprietary cable that runs from your Starlink dish to the router has a connector that can loosen over time, especially if the cable runs in an area with temperature swings or physical stress. Even a cable that looks and feels fully seated may not be making complete contact. A small kink, a pinch point where the cable passes through a wall, rodent damage, or UV degradation on an outdoor run can all cause intermittent signal loss that mimics obstruction problems. Visually inspect the full cable run, check both connectors, and look for any bends sharper than the cable’s natural curve. Gently push both ends in until you feel a firm click. If the cable is damaged, Starlink sells replacement cables through their website.

Old geostationary satellite systems pointed at one fixed spot in the sky. Starlink is completely different: over 6,500 satellites orbit at 550 kilometers, constantly moving, and your dish needs a wide, clear view of the sky in nearly every direction to track them. Even a small object in that path causes real problems.
The Starlink app has a built-in obstruction viewer that shows exactly which parts of the sky your dish is struggling to see. Open the app, tap your dish, and look for the Visibility or Obstruction section. The map fills in over time as satellites actually fly over — a brand-new install won’t show much in the first hour. Wait at least 12–24 hours before making permanent mounting decisions based on the obstruction map. The target for any permanent installation is under 2% obstruction — at that level, most users experience virtually no obstruction-related drops. Between 2% and 5% causes occasional brief interruptions. Above 5% causes consistent, noticeable problems with video calls and streaming. Red areas on the map are where your drops are coming from. The fix is always physical: move or raise the dish.
A location that works perfectly in winter, when deciduous trees are bare, can become unusable by June when leaves fill in. This is one of the most common reasons people experience sudden disconnections that seem to have no explanation — the dish hasn’t moved, nothing was touched, but the service deteriorated sharply. Young trees that seemed harmless at installation can grow into significant obstructions within two or three seasons. If your disconnections began or worsened in spring or early summer, re-run the obstruction check immediately. The fix is usually raising the dish — mounting it higher on the roof, on a taller pole, or in a different location that clears the tree line. Do not plan a permanent mount in winter without running the obstruction check in summer foliage conditions first.
The rule of thumb: from your dish’s mount point, nothing should block a cone reaching 25 degrees above the horizon in every direction, all the way up to directly overhead. This is a wider view than most people assume — it’s not just “clear sky above” but clear sky in a broad arc in every direction. Structures like garages, sheds, tall privacy fences, and utility poles that don’t look like they’d cause problems can be serious obstructions because Starlink satellites often travel at lower angles near the horizon. Higher mounting almost always improves performance — the higher the dish, the more sky it can see. If permanent roof mounting isn’t possible, a rooftop pole mount or mast extension can raise the dish enough to clear surrounding structures. Test placement temporarily on the included ground stand before committing to a permanent mount.
When the app shows no obstruction, weather is clear, and the drops keep coming, the cable and router hardware are the next place to look. These are more straightforward to fix than obstruction problems — no climbing required for most of them.
The most important thing to understand: the Starlink app’s “Reboot” button and a wall power cycle are not the same thing. The app sends a software command that does not fully clear hardware memory states. The wall unplug does. The correct procedure: unplug the power cable directly from the wall outlet — not from the router or from the app — and wait a full 30 seconds before plugging back in. That 30-second wait is not optional; capacitors in the unit need time to fully discharge. After plugging back in, leave the system alone for 5–10 minutes while the dish orients, searches for satellites, and reconnects. Only after that window should you judge whether the problem has resolved. A solid white LED on the router within 3 minutes of completion means you’re connected. Red or dark after 5 minutes means the problem is elsewhere.
The Starlink cable runs from the dish down to the router — and that entire length is worth inspecting, not just the connectors at each end. Common damage points: where the cable passes through a wall or under a door seal; where it bends sharply at a corner; any section exposed to direct sun over long periods (UV degrades the jacket); and areas where animals may have chewed on it. At both ends, push the connector in firmly until you feel a click. A connector that looks fully seated and feels snug may not be making complete electrical contact. Even a minor kink — one that doesn’t look severe — can cause intermittent signal loss that mimics obstruction patterns. If your cable is damaged, replacement cables are available directly from Starlink at starlink.com.
A factory reset clears any corrupted router configuration — a rare but real cause of persistent instability, especially after failed firmware updates. Only do this after you have ruled out obstructions, cable damage, power cycling, and weather. It wipes your Wi-Fi network name and password, so every device on your network will need to reconnect with the new credentials afterward. On Gen 2 systems, a factory reset is triggered by power cycling the router six times in sequence. On Gen 3 units, hold the reset button for 10 seconds. After the reset, set a new network name and password through the Starlink app and wait for the system to fully come online before judging the result. Contact Starlink Support at starlink.com/support if a factory reset doesn’t resolve persistent issues — hardware replacement may be warranted under warranty.
Starlink is more resilient in bad weather than older satellite systems — but it’s not immune. Understanding what weather actually does to the signal helps separate “I need to fix something” from “this is just the technology working as designed.”
Starlink uses Ka- and Ku-band radio frequencies that are absorbed and scattered by water particles in the air. Research published in peer-reviewed journals shows that throughput drops by an average of 27% during any precipitation, with heavier rain causing more severe effects. At moderate rain (about 0.1 inches per hour), most users see minor speed reduction but no disconnection. At heavy rain (0.5 inches per hour or more), brief disconnections are possible. During extreme tropical downpours, drops of 10–30 seconds can occur at peak intensity. You cannot fix rain fade — it is a physics limitation of the frequencies the system uses. What you can do is make sure your dish placement is as clean as possible, because a dish that already has obstruction problems performs significantly worse in rain than one with a clear sky view.
Starlink dishes have a built-in resistive heater that activates automatically when snow or ice accumulates on the surface. In typical snowfall, this is enough to keep the dish clear — the heater melts snow from the center outward and maintains signal with minimal interruption. The problem arises during very heavy, fast snowfall that exceeds the heater’s melting rate. Snow accumulates on the outer edges faster than the heater can clear it, degrading performance until the snowfall slows or stops. Check your Snow Melt setting in the Starlink app — it should be turned on. If you have an off-grid setup with solar or limited battery power, Snow Melt may have been turned off to save power; turn it back on during winter months. If snow accumulates despite the heater, carefully clearing it with a soft brush (never a hard scraper) restores the signal immediately.
Wind itself doesn’t interfere with Starlink’s signal — radio waves pass through air without degradation. What wind does is physically move a dish that isn’t mounted securely. A dish that vibrates or shifts even slightly in gusts loses its tracking alignment and produces intermittent drops that look exactly like obstruction or signal problems but disappear in calm weather. If your drops correlate with wind and not with the direction of gusts, the mount is the problem. The dish should be bolted into solid structural material — roof joists, masonry, or a properly anchored pole — not just into siding or thin decking. If the dish visibly moves or vibrates in strong wind, the mount needs to be reinforced before the next storm.
Some Starlink disconnections are not caused by anything going wrong. They’re a consequence of how low-Earth orbit satellite internet fundamentally works. Knowing this prevents a lot of unnecessary troubleshooting — and sets realistic expectations.
Your dish connects to a satellite moving at 17,000 miles per hour at 550 kilometers altitude. Every roughly 15 seconds, that satellite travels far enough across the sky that your dish needs to hand off the connection to the next satellite in the constellation. These handoffs are engineered to be seamless, and most of them are — but a small percentage cause a momentary packet loss or micro-dropout that is perceptible to real-time applications like video calls, gaming, and VoIP. You’re not imagining these drops. They are documented behavior. For most general internet use — web browsing, email, streaming video — these micro-drops are invisible because applications buffer ahead. For video calls and VoIP calls, a brief freeze or audio hiccup every few minutes may be the irreducible minimum on Starlink.
Starlink’s network is organized into geographic cells. When many subscribers in the same cell are online simultaneously — typically 6:00–10:00 PM local time — speeds drop and latency rises because available capacity is being shared among more users. This is not a dish problem, a cable problem, or an obstruction. It’s a network utilization issue. Starlink’s Priority plans prioritize your traffic during congested periods — if evening slowdowns are significantly affecting your experience, upgrading from a residential plan to one with priority data allocation is the relevant fix. Heavy data activities like large file downloads or video uploads are best scheduled for off-peak hours (late night or early morning) if speed consistency matters to you.
Your data doesn’t travel only between your dish and the satellite. It also has to travel from the satellite down to a regional Starlink ground station gateway connected to terrestrial fiber — then back up the same way. If that ground station experiences any routing issue, users in the entire region may see degraded service or brief outages even when their dish and cable are perfect. Starlink has experienced regional and global outages on several occasions; these are always visible on DownDetector.com and typically resolved by SpaceX within hours. When drops are affecting many users in your area simultaneously and your local setup looks fine, check downdetector.com/status/starlink before further troubleshooting.
The Starlink app contains better diagnostic information than most people ever look at. Two minutes in the Statistics section answers most questions about why you’re dropping.
Open the Starlink app, tap your dish, and go to Statistics. The Outages section shows a log of every disconnection with labels identifying the cause. The two most important labels: “Obstructed” means the dish lost line of sight to a satellite — obstruction or dish placement is the issue. “No Signal Received” means the dish couldn’t find any satellite — this suggests a more complete blockage, a hardware or cable problem, or a network outage. The frequency and duration of entries tells you how serious the problem is. Ten one-second outages is very different from three 30-second outages, even if the total downtime looks similar. The outage graph in the advanced Statistics view shows a 12-hour rolling picture that makes patterns immediately visible.
The Visibility section shows a circular map of your sky view as the dish sees it. Areas filled in red indicate sky coverage that has been blocked during actual satellite passes. A critical detail: the map only fills in data as satellites actually fly over. In the first hour of a new install, you’ll see almost nothing — not because your view is clear, but because not enough satellite passes have accumulated yet. Wait a full 24 hours before making placement decisions based on this map. After that time, red areas reliably identify where your obstructions are. If the entire outer ring of the map is red, your dish view is very constrained and relocation is likely necessary. If just one segment is red, trimming a specific tree or raising the dish may be enough.
If you’re deciding where to place the dish — or considering relocating it — the Starlink app has an augmented reality obstruction check tool that uses your phone’s camera to scan the sky from any location. Open the app, tap Check for Obstructions (found in the Setup section), point your phone upward and rotate through a full circle as prompted. The tool overlays a map of the satellite coverage area your dish needs, with red areas marking detected obstructions. Scan multiple candidate locations before deciding — even moving a dish a few feet can dramatically change what the sky view looks like. Scan from your intended install height, not from ground level, for the most accurate result. Repeat the scan at different times of day if possible, and always consider what the view will look like in full foliage season before committing to a permanent mount.
Work through this in order, giving each step a few minutes before moving to the next. First: unplug the router from the wall — not from the app — wait 30 seconds, plug back in, and wait 10 minutes. Second: check the cable at both ends — push the connectors in firmly until you feel a click. Third: open the Starlink app and look at the Outages section for a cause label. If it says “Obstructed,” the problem is physical placement. If it says “No Signal Received,” check for a regional outage at downdetector.com/status/starlink. Fourth: check the router LED — white or flashing white means it’s working and the problem is elsewhere; red or dark after the power cycle suggests a hardware problem. If none of this restores service, contact Starlink Support through the app or at starlink.com/support — hardware within the first year is covered by warranty.
Video calls and VoIP calls are the most sensitive applications on any connection because they require consistent real-time data flow with almost no tolerance for interruption. On Starlink, a few things help specifically. First, run the obstruction check — even a 2–3% obstruction that doesn’t affect streaming will noticeably impact video calls during satellite handoffs. Second, prioritize wired connections for the device you call from: use an Ethernet adapter to connect your laptop or desktop directly to the Starlink router rather than relying on Wi-Fi, which adds a second layer of variability. Third, check whether your calls drop at the same times each day — a consistent pattern points to an obstruction on a satellite path. Brief freezes a few times per hour during good conditions are a known Starlink limitation for real-time applications and cannot be fully eliminated — only reduced.
This is one of the most genuinely difficult Starlink situations. When you can’t clear the tree line, a few options remain. A rooftop pole mount extension — available as third-party hardware for Starlink dishes — adds 4–8 feet of height above the roof peak, which can be enough to clear many obstruction problems. If there is any location on the property with better sky visibility — a corner of the yard, a detached garage roof — Starlink has cable extension options and long third-party runs that can reach that location. Before purchasing hardware, walk around your property with the Starlink app’s obstruction check tool running and scan from the highest accessible point you can safely reach. Sometimes a 10-foot move combined with a different roof slope changes the sky view entirely. Contact Starlink Support to discuss mounting options for your specific situation.
RV and in-motion use creates a fundamentally different problem than residential installs. A moving dish is constantly reacquiring satellites as its position and angle change, which produces more frequent drops than any fixed installation. You need the Starlink RV or Flat High Performance plan to use the dish legally while in motion — the standard residential dish is not approved for mobile use and will perform erratically if attempted. If you’re on the correct mobile plan and still dropping constantly, the most common cause is the dish mount vibrating or shifting on the vehicle. Verify the mount is secure with no play or flex. When parked, always run the obstruction check from the parked location before judging connection quality — parking spots in campgrounds and RV parks often have severe tree obstruction.
The dish’s built-in heater handles typical snowfall, but heavy snow can accumulate on the outer edges of the dish faster than the heater can clear it — temporarily blocking signal until the snowfall rate slows. Two steps: First, confirm Snow Melt is turned on in the Starlink app under Settings. If you have an off-grid or solar setup, Snow Melt may have been disabled to conserve power — turn it back on before winter. Second, if snow has already accumulated and the heater isn’t keeping up, clear it carefully with a soft-bristled brush. Never use a hard scraper, ice pick, or anything abrasive on the dish surface — the protective coating can be damaged, which creates permanent signal problems that weren’t there before. If Snow Melt is on and heavy accumulation is still a persistent problem, a dish cover or shelter that keeps snow off while allowing signal through is a mechanical option some users in high-snowfall areas have added.
If you’ve confirmed clean obstruction scores in the app, the cable is intact and firmly seated, weather isn’t a factor, and power cycling the router doesn’t help — it’s time to contact Starlink directly. Reach Support through the Starlink app (the fastest path) or at starlink.com/support. When you contact them, have ready: the outage log labels from the app (Obstructed, No Signal Received, etc.), how long the problem has been happening, what you’ve already tried, and your dish’s hardware generation (Gen 2 or Gen 3). Hardware within the first year is covered by Starlink’s warranty at no cost. If you’re outside warranty and the dish or router is diagnosed as faulty, Starlink sells replacement hardware through the same portal. Gen 1 router owners should also check their accounts — Starlink has offered a free Router Mini replacement to Gen 1 owners under certain conditions.
