Starlink was fast when you first set it up. Now it feels sluggish during evenings, buffers on video calls, or crawls when it used to sprint. This happens — and most of the causes are diagnosable in under 10 minutes. Some you can fix yourself tonight. A few you can’t fix at all, but you can at least stop blaming yourself for them.
The questions Starlink users search when speeds drop — answered directly so you can find your problem fast and stop chasing the wrong fix.
Almost certainly network congestion — and it’s the most common complaint among Starlink users who have been on the service for several months. Starlink divides coverage into geographic “cells.” As more households in your area sign up for Starlink, more dishes share the same satellite bandwidth during peak hours. The 6–10 PM window is when this hits hardest, because that’s when most of your neighbors are also streaming, gaming, and working on video. Nothing about your equipment changed. Your area got busier. The fix: check whether speeds bounce back after 11 PM. If they do, congestion is confirmed. Your options are upgrading to the MAX plan (which gets network priority over lower tiers during congestion), scheduling large downloads for off-peak hours, or simply accepting that evening speeds will be lower until SpaceX adds more satellite capacity over your cell.
Open the Starlink app and navigate to Statistics → Outages. You’ll see a count of how many seconds of connectivity you’ve lost in the last 24 hours. Even one second of outage every few minutes is enough to cause video to buffer, calls to glitch, and gaming to lag — even when speed tests show acceptable download numbers. For a fuller picture: go to the Obstructions screen in the app. After your dish has been running for 10–15 minutes, it generates a real-time map showing exactly which directions in the sky are blocked. Red zones are obstructions. Target: under 2% sky blockage for reliable service. Under 1% is excellent. Above 5% causes noticeable dropouts every 10–30 minutes. Trees are the most common obstruction — and they get worse in summer when leaves fill out. A dish that worked perfectly in March may struggle by June.
This is almost always one of two things: obstructions causing brief signal dropouts that don’t show up as “slow” on a speed test but do interrupt streaming buffers, or Wi-Fi signal weakness between your router and the device you’re watching on. A speed test is a single sustained measurement — it smooths over brief interruptions. Streaming video needs a consistent, uninterrupted signal. A 0.5-second dropout from a tree branch crossing your satellite path will cause a streaming app to pause and reload its buffer, even though your average speed is 150 Mbps. To tell them apart: run the Starlink app obstruction check and look for outage seconds. Then plug a laptop directly into your router via Ethernet cable and test streaming there. If it streams fine over Ethernet but buffers on Wi-Fi, your problem is Wi-Fi coverage, not the dish or the satellite. If it still buffers on Ethernet, look at obstructions or congestion.
Yes — rain and heavy snow genuinely reduce throughput, not just during the storm but during the approach and clearing. Starlink uses Ka-band radio frequencies, which are absorbed by water molecules in the atmosphere. Heavy rain can temporarily reduce signal quality by up to 50% in some locations, according to independent testing. The good news: Starlink is significantly more weather-resistant than older geostationary satellite services because its satellites are much closer — less atmosphere for the signal to traverse. Light rain, clouds, and fog have almost no measurable effect. Heavy thunderstorms and dense snowfall cause real but temporary slowdowns. Your dish also has a built-in snow-melt mode that runs the dish warm enough to shed accumulated snow and ice — which is why power consumption spikes in winter. If your speeds drop and recover once a storm passes, weather was the culprit. No fix needed — it’s a temporary physics problem, not something you broke.
More often than people realize, yes. The Starlink dish and satellite may be delivering excellent speeds right up to the Gen 3 router — but if you’re testing on a phone or laptop on the far side of a concrete wall, two floors up, or in a detached garage, what you’re measuring is Wi-Fi range, not Starlink performance. Walls reduce Wi-Fi signal. Concrete and brick cut it severely. Metal objects scatter it. Microwaves running in the kitchen can interfere with the 2.4 GHz band. The single most useful test: run a speed test on a device connected via Ethernet cable directly to the router. If wired speeds are fast but wireless speeds are slow, the dish is fine and your fix is router placement or a mesh node — not a Starlink support ticket. Starlink’s official guidance: place the router centrally, in the open, away from walls and metal, at least 20 feet from major appliances.
Yes, but probably not in the way you think. The dish can handle dozens of connected devices without trouble. What actually causes slowdowns is when multiple devices are actively downloading or streaming large amounts of data simultaneously — a 4K stream on the TV, a firmware update downloading on a game console, a video call on a laptop, and a cloud backup running on a phone all at the same time will compete for bandwidth. Also: older Wi-Fi devices connecting to your Gen 3 router can pull other devices down to their speed level in some network configurations. Starlink’s official recommendation is to split your Wi-Fi bands — connect high-demand devices (smart TVs, computers, gaming consoles) to the 5 GHz band for speed, and move older/slower devices (smart lights, security cameras, thermostats) to 2.4 GHz. You can also check which devices are currently using the most bandwidth through the Starlink app under the Network tab — often one device running an update explains a household-wide slowdown.
It’s possible and worth checking. Open the Starlink app and go to Network → Connected Devices. Every device currently using your Wi-Fi will be listed. If you see devices you don’t recognize, someone may be on your network — a neighbor who got your password, a device from a previous resident, or occasionally a poorly named device of your own. The fix: change your Wi-Fi password through Settings → Wi-Fi Settings in the Starlink app. This disconnects every device currently connected, requiring them to reconnect with the new password. Do this, then reconnect only your own devices. An unauthorized user on your network could be streaming, downloading, or uploading constantly, consuming bandwidth invisibly. It’s not common but worth ruling out early in troubleshooting, especially if speeds are slow at all hours rather than just evenings.
Every reason Starlink slows down, whether it’s fixable, and how long the fix takes. Use this to pinpoint your problem before digging into the detailed solutions below.
| # Cause | How to Confirm It | Fix Available? | Time to Fix |
|---|---|---|---|
| 1 · Peak-hour congestion | Speeds fast at 10 AM, slow at 8 PM | Partial — upgrade to MAX plan or schedule off-peak | Plan change via app |
| 2 · Dish obstructions (trees, chimney, roof edge) | App → Statistics → Outages shows lost seconds | Yes — relocate dish higher or trim trees | 1–4 hours (mounting job) |
| 3 · Wi-Fi dead zones / router placement | Wired speeds fast; wireless slow in certain rooms | Yes — move router centrally or add mesh node ($40) | 30 minutes |
| 4 · Heavy rain or dense snow | Speeds drop during storm, recover after | No fix — temporary physics limitation | Waits for weather to clear |
| 5 · Too many devices streaming simultaneously | Check app Network tab during slowdown | Yes — identify hog device, split Wi-Fi bands | 15 minutes |
| 6 · Unauthorized device on your network | App → Network → Connected Devices (any unknowns?) | Yes — change Wi-Fi password in app | 5 minutes |
| 7 · Router needs restart / firmware update | Speeds poor on all devices; reboot fixes briefly | Yes — power cycle router; updates auto-apply | 5 minutes |
| 8 · Snow or ice on the dish | Sudden outage in winter; dish normally self-heats | Yes — let dish heat itself; do not pour hot water | 20–60 minutes (heating) |
| 9 · Deprioritized plan tier (100/200 Mbps) | Slow only during congested hours; improves late at night | Partial — upgrade to MAX for full network priority | Plan change via app |
The table above is the quick view. This section gives you everything you need to actually solve each problem — including which fixes take five minutes and which require a ladder.
Starlink divides coverage into satellite cells — geographic zones where all subscribers share available bandwidth from the same passing satellites. When that cell fills up with active users during the evening streaming rush, speeds drop for everyone on deprioritized plan tiers. This is identical in concept to traffic slowing down on a highway when more cars join at rush hour. Real user data from early 2026 confirmed that some users in previously fast areas were seeing speeds drop to 20–50 Mbps in the evenings after their area added more subscribers. How to confirm it: open the Starlink app and run a speed test at 10 AM, 3 PM, and 9 PM. If the morning is fast and the evening is slow, congestion is your answer. The fix options: (1) upgrade to the MAX plan for network priority — MAX traffic is served before lower-tier traffic during congestion; (2) schedule bandwidth-heavy tasks like software updates, large downloads, and TV catch-up for after 11 PM when congestion eases; (3) accept that evenings are slower and adjust expectations rather than troubleshoot hardware that isn’t broken.
Starlink’s dish needs a wide, unobstructed view of the sky — not just a clear patch directly above. Because its satellites move continuously across the sky, even a tree branch that blocks a small arc for a few seconds as a satellite passes behind it causes a dropout. These brief outages appear as buffering and latency spikes even when average speed tests look acceptable. A dish with 5% or more sky blockage will cause noticeable interruptions every 10–30 minutes. To diagnose: go to Statistics → Outages in the Starlink app. Any outage time at all is worth investigating. Then open the Obstructions map — after the dish has been running 10–15 minutes, it shows a live heat map with red zones where signals are blocked. Aim for under 2% blockage; under 1% is excellent. The fix: raise the dish higher (a taller pole mount or roof mounting vs. ground mounting makes a dramatic difference), or clear obstructions like trimming branches. One user reported their obstruction went from every 21 seconds to effectively zero by moving the dish from ground level to the roof peak — with Apple TV stopping its freeze-and-restart behavior entirely.
The Gen 3 Starlink router covers roughly 3,200 square feet under ideal conditions — single-story, open floor plan, no concrete walls. In a two-story home, a home with thick plaster or brick walls, a long ranch-style layout, or a property with a detached workshop or garage, the Wi-Fi signal from a single router simply doesn’t reach everywhere reliably. The dish and satellite may be delivering 150 Mbps to the router, but if your phone or TV is pulling 12 Mbps in the back bedroom, the culprit is Wi-Fi range, not Starlink. The diagnostic test is simple: plug a laptop into the Starlink router using an Ethernet cable and run a speed test at speedtest.net. If that shows fast speeds but your wireless device in another room is slow, Wi-Fi is the problem. Fixes: move the router to a more central location in your home; place it in the open (not in a cabinet or behind a TV), elevated off the floor; split your 5 GHz band for fast devices nearby and 2.4 GHz for distant devices; or add a Starlink Router Mini ($40) as a mesh node placed halfway between the router and the dead zone.
Starlink uses Ka-band frequencies between 26 and 40 GHz. Water absorbs and scatters these radio waves — which is why heavy precipitation temporarily reduces signal strength. A moderate rainstorm might drop speeds by 20–30%. A severe thunderstorm directly overhead can knock service out briefly. Dense snow similarly absorbs the signal before it reaches the dish. The effect is proportional to precipitation intensity, not weather severity in general — light rain, fog, and clouds cause almost no measurable impact. Your dish handles accumulated snow automatically: it heats itself to shed snow and ice, so do not pour hot water on the dish or try to brush snow off while it’s powered on (you risk damaging the dish or mount). This is not something you broke and not something you can fix. Speeds recover once the precipitation passes. The Starlink app’s Status page will often show “Searching” or “Obstructed” during heavy precipitation events.
A single device can quietly consume most of your household’s available bandwidth without anyone realizing it. A game console downloading a 60 GB game update. A smart TV pulling a firmware update overnight. A computer performing a cloud backup. A security camera system uploading footage to cloud storage continuously. When these happen in the background during prime household use hours, everyone else’s stream buffers and video calls stutter. Find the culprit: open the Starlink app → Network tab. It shows every connected device and how much bandwidth each is currently using. The one at the top of that list with a high data rate is your problem. Pause or schedule that download for late night. Then split your Wi-Fi bands: connect 4K TVs, gaming consoles, and computers to the 5 GHz band; push smart lights, thermostats, security cameras, and older slow devices to 2.4 GHz so their traffic doesn’t compete with your primary devices.
Someone using your Wi-Fi without permission — a neighbor who got your password, a device left behind by a previous resident, or a forgotten device on your network — could be consuming significant bandwidth continuously. This is worth ruling out early because it’s completely invisible without checking. Check now: open the Starlink app → Network → Connected Devices. Every device on your network appears here with a device name and current usage. Look for anything you don’t recognize. Smartphones, laptops, tablets, smart TVs, and game consoles will be listed by manufacturer name — anything that says “Unknown,” that has an unusual name, or that you simply don’t account for should be investigated. The fix: go to Settings → Wi-Fi Settings in the app and change your Wi-Fi password. Every device disconnects and must reconnect with the new password. Only reconnect devices you own. This also lets you audit which devices actually need to be on your network versus devices you’ve accumulated over time that are quietly using data.
Network equipment accumulates temporary errors over time — cached routing tables that become stale, memory leaks in firmware, and connection states that get stuck. Restarting the router clears all of this and re-establishes a clean connection. It sounds too simple to be the answer, but it genuinely resolves a surprising number of slow-speed and intermittent connectivity complaints. Starlink’s Gen 3 router pushes firmware updates automatically when they’re available, and some updates require a restart to take full effect — if the router hasn’t been restarted in weeks, it may be running outdated firmware or holding a pre-update connection state. How to restart correctly: unplug the power cable from the router (not from the wall outlet — from the router itself), wait 30 full seconds, then plug it back in. Wait 2 minutes for the router and dish to fully reconnect before testing speeds. If speeds improve immediately, the restart solved it. If they fall back to slow after an hour, the problem is something else — a restart bought temporary relief from a symptom, not a fix for the underlying cause.
The Starlink dish has a built-in heating element that runs when ice or snow accumulates on the dish surface — it warms itself just enough to melt the ice and shed precipitation. This process is automatic and works reliably in most winter conditions. The dish may run noticeably warmer to the touch in winter, and your power consumption will increase by 50–100 watts during heating. If your power goes out during a snowstorm and comes back on, the dish will need 20–60 minutes to heat and clear itself before signal quality fully recovers. What not to do: do not pour hot water on the dish — thermal shock can crack the dish housing or damage internal components. Do not use a scraper or brush while the dish is powered on. Do not manually tilt the dish to shed snow — the dish automatically adjusts its angle as needed. If the dish is covered in deep snow that isn’t melting after an hour or more with power on, check that the dish is actually receiving power (the router should show connected). A severe ice coating from freezing rain rather than snow can occasionally overwhelm the heating system — in that case, power cycling the dish (unplug the router for 30 seconds) sometimes helps by resetting the heating cycle.
The Residential 100 Mbps and 200 Mbps plans have their traffic deprioritized behind MAX plan subscribers during periods of network congestion. This means when the satellite cell is under load during peak hours, MAX subscribers get their speeds sustained first, and lower-tier subscribers get what’s left. In uncongested areas, this doesn’t matter — everyone on the cell gets fast speeds because there’s enough bandwidth for all. In areas with high Starlink adoption, the deprioritization becomes tangible: a 200 Mbps plan subscriber in a busy cell might see 25–35 Mbps at 8 PM while a MAX subscriber in the same cell sees 90–120 Mbps. How to confirm this is your problem: run speed tests at 2 AM versus 8 PM. If late-night speeds are dramatically better, your plan is being deprioritized during congestion. The fix is upgrading to Residential MAX ($130/month) through the Starlink app. There’s no contract and no penalty for upgrading or downgrading at any time.
Run through these steps in order. Each one takes two minutes or less. Stop at the first one that gives you a clear answer.
This pattern has one answer: peak-hour congestion on your satellite cell. Your dish and satellite link are working correctly. The problem is that many other Starlink dishes in your area are all active at the same time between 6 and 10 PM, and the shared bandwidth gets stretched thin. There is no equipment fix for this. Your options are: switch to the MAX plan ($130/month) to get network priority and be served before lower-tier traffic during congestion; schedule data-heavy tasks (streaming downloads, game updates, large file transfers) for after 11 PM when the cell quiets down; or accept that Starlink in your area has hit peak-hour capacity and use the connection for lighter tasks during busy evenings. If you’re on the 100 Mbps or 200 Mbps plan, upgrading to MAX is the most direct fix because your current plan is deprioritized behind MAX traffic during congestion — you’re literally in the back of the line during the exact hours you most want fast internet.
Video calls are highly sensitive to packet loss — tiny brief interruptions that a speed test wouldn’t catch but that a live video stream definitely will. The most likely culprit for call freezing on Starlink is obstructions causing brief signal dropouts when a satellite passes behind a tree or roof edge. Check the Starlink app for any outage time — even 1–2 seconds per hour of outage creates exactly the freeze-and-recovery behavior video calls show. Second suspect: your Wi-Fi signal to the device you’re calling from. If possible, plug your laptop directly into the router with Ethernet during calls — this eliminates Wi-Fi as a variable entirely. Ethernet connections to the Starlink router (via the Ethernet Adapter, $35) are significantly more stable for real-time applications than Wi-Fi. Third: if calls freeze at the same time every evening regardless of weather, congestion during peak hours is degrading the connection. Upgrading to MAX improves priority during those hours.
This is a Wi-Fi range problem, not a Starlink problem. Your dish and satellite connection are likely working fine. The signal from your Gen 3 router simply isn’t reaching the back bedroom at full strength. Wi-Fi signal is reduced by distance, walls, floors, and materials — concrete and brick are particularly damaging. The fix: add a Starlink Router Mini ($40 from shop.starlink.com) and place it halfway between the main router and the weak area. It pairs wirelessly with the main router in about 5 minutes through the Starlink app and extends Wi-Fi coverage by up to 1,300 additional square feet. Alternatively, run an Ethernet cable to a mesh node in the back of the house for the strongest possible connection. Starlink’s guidance: mesh nodes should be placed one to two rooms apart, paired directly to the main router (not chained through another mesh node), and positioned in the open rather than in cabinets or closets.
Trees. Specifically: deciduous trees (the kind that lose their leaves in winter) have full foliage in summer and are significantly worse obstructions than bare branches in winter and spring. A tree that was 20 feet from your dish and mostly bare in March may have a full canopy reaching toward your dish’s sky view by July. The Starlink app’s obstruction map shows this in real time — the red zones will be more prominent now than they were in your first speed-test screenshots from early spring. The fix is either trimming the offending branches (check with your local municipality if the tree is on a property line) or raising the dish higher on a taller pole mount to clear the tree line. Raising the dish by 5–10 feet can completely eliminate a moderate tree obstruction. If trimming or relocating isn’t practical, check whether the loss is isolated to certain times of day — trees at the east side of your property cause problems in morning when satellites track through that arc, while western obstructions affect evenings.
Brief, regular disconnections — not slow speeds, but actual signal drops lasting 1–5 seconds every few minutes — are the classic signature of obstruction. Something is blocking the satellite path for a moment each time a satellite passes behind it. Open the Starlink app → Statistics and look at how many outages have occurred in the last 24 hours. Then check the Obstructions heat map for red zones. This pattern is also consistent with Starlink’s satellite handoffs — every 15 seconds, the system switches between satellites (at 12, 27, 42, and 57 seconds past each minute). Usually these handoffs are seamless. On a cell with limited satellite coverage or during handoffs where the next satellite is also partially obstructed, brief gaps occur. If disconnections are genuinely regular at a predictable interval, obstruction is the most likely explanation. The Starlink app will show you exactly how many seconds of outage you’re accumulating.
Starlink has no phone support line. All technical support is handled through the app and online ticket system. If you’ve worked through the diagnostic steps in this guide and the problem persists, here’s how to get help: open the Starlink app → Support → Submit a Ticket. When writing the ticket, include: what speeds you’re seeing at different times of day (attach speed test screenshots), what outage time the Statistics screen shows, what your obstruction percentage is from the obstruction map, and what troubleshooting you’ve already tried (including the router restart). The more specific your ticket, the faster a useful response comes back. Response times range from a few hours for common issues to several days for complex hardware questions. If you suspect a hardware defect — the dish or router itself is failing rather than any of the situational causes above — Starlink does provide hardware replacement under its warranty; include photos of the hardware and any LED status lights in your ticket.
All Starlink support is handled through the app and website. There is no phone number for residential customers — but the app tools are more useful than a phone call for diagnosing most problems.
