Severe thunderstorms, heavy rain, snow, hail and ice can interrupt a satellite connection, but the fault may be miles away from your house. Your dish can have a clear view of the sky while a provider gateway or other remote network site is in bad weather. First check for a reported outage and wait through the worst conditions; then check indoor equipment, restart it using your provider’s instructions, and inspect snow or ice only from a safe position. If service remains down after the weather clears, treat it as a possible power, cable, line-of-sight, equipment or network problem and contact the provider.
Why bad weather can stop satellite internet
Satellite internet depends on a radio path between the dish at your property, an orbiting satellite and a ground gateway that connects the satellite network to the wider internet. Water and ice in that path can weaken the signal. The gateway may also be in a storm even when the sky above your home is clear.
Rain, thunderstorms and hail
Heavy precipitation can produce temporary or intermittent loss, often called rain fade. Hughesnet and Viasat say ordinary cloud cover, light rain and fog usually have little effect on service. Starlink’s official support guidance says moderate to heavy rain, snow and hail can cause momentary dropouts. Do not assume every provider reacts at the same precipitation level: antenna design, frequency, network configuration and local conditions differ.

Snow and ice on the antenna
Snow that accumulates on or completely covers a dish can block or weaken reception. Starlink says heavy snow completely covering the dish may cause intermittent connectivity or temporary loss of service. Ice can have a similar effect and may add weight or change the antenna’s alignment. Clearing buildup helps only when the buildup is the cause; it cannot fix a distant gateway outage or a damaged cable.

A storm at a remote gateway
The satellite path includes ground infrastructure outside your property. A gateway serving your area can be affected by flooding, lightning, wind or heavy precipitation while you see blue sky. Therefore, a clear local view does not prove that weather is unrelated to the outage.
How long should you wait?
During active severe weather, wait for conditions to improve before repeatedly rebooting equipment. Many weather-related interruptions recover automatically. Viasat states that typical weather outages usually last no more than 20 minutes, even when rain or snow continues, but that is provider-specific guidance rather than a guarantee for every storm, plan or location. Hughesnet likewise says service restores itself when weather clears. A longer outage, a completely storm-free outage or repeated failures after every storm deserves troubleshooting.
Check for a provider outage before changing anything
Use the provider’s current status page, mobile app or automated outage line first. A network event can make home troubleshooting ineffective, and a provider may already be working on a gateway or regional fault. Viasat lists its mobile app and an automated outage phone line, although availability varies by location. Sign in over a phone’s mobile connection if your satellite link is unavailable.

Follow this troubleshooting sequence
1. Let the most dangerous weather pass
Do not go outside near lightning, high winds, flooding or unstable snow and ice. A temporary signal loss during intense precipitation is expected behavior for some systems. Waiting through the peak of the storm also prevents a reboot from being mistaken for a cure when the signal would have returned naturally.
2. Check power and indicator lights indoors
Confirm that the modem or gateway, its power adapter and the router are connected to a live outlet. Check for a tripped breaker, switched-off power strip or water intrusion near indoor equipment. Read the status lights using the equipment manual or your provider’s light guide; the meaning of red, amber, flashing or unlit indicators differs by model.
3. Reseat the cables
With equipment powered down if the manual requires it, verify that the coaxial cable from the dish and the Ethernet cable to the router are firmly seated. Look for a loose connector, bent pin, crushed section or cable that has been pulled by wind or falling branches. Do not open sealed outdoor components or make a new roof penetration during a storm.

4. Restart equipment according to the provider
Use the exact sequence for your service rather than a generic internet reboot:
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errors| Provider guidance | Restart procedure | What to expect |
|---|---|---|
| Viasat | Unplug the modem or gateway for 30 seconds, reconnect it, and wait before reconnecting a separate router. | Allow 5–10 minutes for the modem or gateway to come online. Bring the modem online before powering the separate router back up. |
| Hughesnet | Remove power from the modem at the wall for 10 seconds, then reconnect it. | Use the modem lights and provider diagnostics to confirm whether service returns. |
| Other providers or equipment | Use the current instructions in the provider app, manual or support site. | Timing and light patterns can vary by model, plan and geography. |
Do not cycle power repeatedly while the system is acquiring a signal. One correctly timed restart followed by the provider’s specified wait is more useful than several rapid reboots.
5. Run the provider’s diagnostics
Viasat’s My Viasat app includes a modem diagnostic. Other providers expose similar tests through an app or account portal. Run the test after the modem has had time to reconnect and save any error code or message. A diagnostic can distinguish a service outage from a local equipment or signal problem, but it cannot make an unsafe dish accessible.

Deal with snow or ice only when it is safe
Never climb onto a roof, ladder or icy platform during or immediately after a storm to reach an antenna. Falling snow, hidden ice, wet shingles and strong wind create a serious risk, and a satellite dish can be mounted in a place that is not safely serviceable by a homeowner.
If the dish is safely reachable from the ground
Remove loose snow gently with a soft brush or by following the provider’s instructions. Starlink warns against picks, chisels and scrapers, which can damage the antenna surface. Viasat says an easily accessible antenna may be wiped clean. Do not strike, twist or lean on the dish, and stop if ice is bonded to the surface.
Use built-in snow management where available
Starlink’s app includes a Snow Melt setting with Automatic, Pre-heat and Off modes. Pre-heat can use more power, so select it only when needed and follow the current app instructions. A snow-melt feature cannot remove thick ice mechanically and does not address rain fade or a gateway outage.

Use symptoms to separate weather from a local fault
| What you observe | Most useful next step |
|---|---|
| Brief dropouts only during intense rain, hail or snow | Wait for precipitation to ease, check outage status and monitor recovery. |
| Several nearby subscribers are offline while your equipment has power | Check the provider’s regional outage notice and avoid repeated reboots. |
| Only your home is offline after the storm | Inspect indoor power, modem lights, coax and Ethernet connections; run diagnostics. |
| Service returns after every reboot but fails again when equipment warms or the next storm arrives | Ask the provider to investigate equipment, cabling, grounding and signal levels. |
| The dish is visibly covered with snow or ice | Use a safe ground-level method or request professional service; never take a roof-access risk. |
| There is no service in clear weather for an extended period | Escalate after checking status, equipment and diagnostics; weather alone is no longer a sufficient explanation. |
When to contact the internet provider
Contact support when service has not returned after weather clears and the provider’s recommended restart has completed, or when diagnostics show a fault. Also call when the dish, cable or mounting hardware appears damaged, when the modem shows an unexplained persistent error, or when outages recur in otherwise moderate conditions.
Give support a concise timeline: the time service failed, precipitation and wind conditions, whether neighbors or the outage tool reported a problem, the modem light pattern, the restart you performed and any diagnostic code. Ask whether the issue is a gateway outage, a signal-level problem, damaged outdoor wiring, misalignment, power equipment or a failed modem. Provider contact details and app names can change, so use the current support channel shown in your account.
What not to do
- Do not climb onto a roof or ladder during rain, ice, high wind or lightning.
- Do not scrape a dish with a knife, pick, chisel or metal tool.
- Do not move or rotate the antenna to “find” a signal; alignment is engineered and a small change can make service worse.
- Do not assume a clear sky at your house rules out a provider outage.
- Do not treat one provider’s reboot timing as universal. Viasat’s 30-second unplug and 5–10-minute reconnection window is different from Hughesnet’s 10-second power removal instruction.
- Do not install unapproved heaters, covers or sealants over the antenna without provider guidance.
Provider guidance at a glance
The following comparison summarizes published support guidance, not a controlled performance test. It should not be read as a ranking of reliability.
| Provider | Weather guidance | Automatic recovery statement | Snow or ice advice | Published troubleshooting emphasis |
|---|---|---|---|---|
| Hughesnet | Light rain, ordinary clouds and fog generally have little effect; severe weather can interrupt service. | Says internet restores itself when weather clears. | Inspect only when safe; follow current equipment instructions. | Check equipment and power, then contact Customer Care if service does not resume after weather clears. |
| Viasat | Typical weather outages are associated with heavier rain or snow; ordinary cloud cover and light precipitation usually have little effect. | Says connectivity returns without action after a loss; typical weather outages usually do not last more than 20 minutes. | An easily accessible antenna may be wiped clean. | Use the app or outage line, reboot the modem or gateway for 30 seconds, wait 5–10 minutes, then use My Viasat diagnostics. |
| Starlink | Moderate to heavy rain, snow and hail can cause momentary dropouts. | Weather-related interruptions may end as conditions improve. | Heavy snow covering the dish can cause intermittent or temporary loss; the app offers Automatic, Pre-heat and Off Snow Melt modes. Avoid picks, chisels and scrapers. | Check the app and equipment status, keep the dish clear only when safely reachable, and seek support for persistent loss. |
What a persistent outage may mean
If the connection stays down after the storm, possible causes include a tripped or failed power supply, water-damaged connector, damaged coax, a router or modem fault, dish misalignment from wind, an obstructed line of sight, or a provider-side gateway or network failure. These causes can look similar from a web browser, so the provider’s light guide, diagnostic tool and signal tests are more useful than repeatedly refreshing a website.
A weather trigger does not prove weather is the only cause. For example, wind can expose a loose cable, falling debris can block the dish, and an outage that began during rain can continue because a connector or power component was damaged. Report the timing and visible evidence rather than asking support to replace equipment immediately; a technician can determine whether the fault is local or network-side.
Quick Recap
A practical decision checklist
- Stay indoors until lightning, dangerous wind, flooding and unstable ice have passed.
- Check the provider’s outage status using mobile data if necessary.
- Confirm power, modem or gateway lights, coax and Ethernet connections.
- Perform one restart using the provider’s exact timing and wait for full reconnection.
- Run the provider’s diagnostic and record the result.
- Inspect snow or ice only from a safe, ground-level position; use the provider’s approved method.
- Contact the provider if service remains out after conditions improve, diagnostics fail, equipment is damaged or outages recur.
