Can the Starlink router go in the attic, garage or basement?
Where the cable comes in isn't always where the router should live. Heat, cold and floors decide whether that spot works.
- Starlink's weather article lists 32 °F to 86 °F for the router and power supply indoors.
- Unconditioned attics and many garages leave that indoor range for part of the year.
- Starlink says the power supply shuts itself off if it gets too hot, which drops the connection, so give it room to cool.
- A basement usually keeps the gear comfortable but leaves upstairs Wi-Fi weak; a mesh router or an Ethernet run fixes that.
- The Router Mini is for indoor use only and isn't waterproof.
Keep the Starlink router and its power supply in the heated and cooled part of the house. Starlink’s weather article lists 32 °F to 86 °F for both indoors, most attics and many garages leave that range for part of the year, and the Router Mini isn’t waterproof.
The Starlink cable often comes into the house at the garage, the attic or the basement, and parking the router right where it lands is tempting. Here’s what each of those rooms does to the gear and to your Wi-Fi.
The temperature Starlink lists for indoor gear
Starlink’s weather article gives one line for the indoor equipment: “Router and power supply, indoors | 0 °C to 30 °C (32 °F to 86 °F)”.
Its router spec articles list a wider range, and Can Starlink overheat? sets the two side by side; this post plans around the narrower one.
Two more Starlink facts shape the choice:
- The power supply protects itself. Starlink says: “The power supply has internal safety features that shut it off if it gets too hot. That shutdown drops the network connection. Ventilation prevents that shutdown.”
- The routers are indoor gear. Starlink says the Router Mini “is indoor only (not waterproof). Do not place it outside.” Router 3 carries an IP56 rating but is still listed for indoor use.
| Room | Typical conditions (our reading, not measured) | Wi-Fi to the living space | Verdict |
|---|---|---|---|
| Unconditioned attic | Often far above 86 °F in summer | Poor for the floors below | Avoid |
| Garage | Below 32 °F in northern winters, above 86 °F in southern summers | Through an outside-grade wall | Avoid unless heated and cooled |
| Basement | Usually cooler and steadier | Weak upstairs | Fine for the gear; add mesh or Ethernet |
| Central shelf in the living space | Within range | Best | Aim for this |
Attic: heat in summer, and why a router up there covers less than you think
An unconditioned attic traps summer heat, and a satellite-equipment retailer’s blog warns against putting electronics up there (Solid Signal). On a July afternoon in most of the country, that puts the router and power supply outside Starlink’s indoor range for hours.
Coverage suffers too. Starlink’s Wi-Fi tips say to place the router in the part of the home where you use your devices most, and that the connection is best in the same room or one to two rooms away. From the attic, every device sits below a ceiling, insulation and often ductwork, and the ground floor may be two floors away. Starlink also lists metal among the things to keep the router 20 feet from, and attics often hold metal ducts and, in some homes, a radiant barrier.
The dish doesn’t belong in the attic either. Roofing blocks the sky it needs: see window, indoors and attic.
Garage: cold, heat, dust and the power supply’s need to breathe
A garage swings with the weather. In northern winters it can drop below 32 °F, the bottom of Starlink’s indoor range. In southern summers, a closed garage can run far above 86 °F.
Owners report both problems. One TractorByNet member describes a Starlink power supply running hot enough to soften the plastic shelf under it, in a garage that also dropped below freezing (TractorByNet).
Garages also tempt people to tuck the gear away. Starlink’s tips say not to put the router in a cabinet, and the power supply needs open air to cool. Between the garage and your living room there’s usually an outside-grade wall, and Starlink says several walls between rooms can lower coverage.
If the garage is the only option, it should be insulated, heated and cooled, with the router on an open shelf at least halfway up the wall.
Basement: temperature is fine, the floor above is the problem
Basements usually stay cooler and steadier than attics or garages, so the gear itself is often comfortable. Keep it off the floor anyway: Starlink says a surface at least halfway up the room is better than the floor, and the Router Mini isn’t waterproof.
The catch is Wi-Fi. Every device upstairs sits on the other side of a floor, and foundation walls are concrete or block. Starlink says to keep the router at least 20 feet from metal, concrete and brick, and that brick, stone or several walls can lower coverage.
How far a router reaches depends on which one comes with your kit. Starlink lists Router 3 at about 3,200 sq ft and the Router Mini at about 2,200 sq ft. Its shop listing gives Router 3 a smaller figure, around 2,000 sq ft per router based on customer surveys, and notes that homes with stone or concrete walls may need extra routers. Our reading: a basement router in a two-story house covers the basement and part of the main floor at best.
Get the router to the middle of the house: cable route, Ethernet or mesh
You have three ways to move the Wi-Fi to where people actually use it.
- Route the Starlink cable farther in. The cable guide covers the lengths Starlink sells, its no-splice rule and routes through attics and basements.
- Add a Starlink mesh router. Starlink says a mesh router connects to the main router and extends Wi-Fi into weak areas. Place it between the main router and the weak rooms, 1 to 2 rooms from the main router; Starlink’s troubleshooting article says to space mesh nodes 30 ft apart. Use no more than three.
- Run Ethernet upstairs. Keep the Starlink router near the cable entry, inside conditioned space, and run Ethernet to a mesh router or your own router in the middle of the house. The Wi-Fi guide covers both.
If power flickers often where you live, there’s one more reason to keep the gear somewhere easy to reach: Starlink says the router factory-resets after 6 power cycles in a row, which can happen in outages. A small battery backup in front of the power supply is our suggestion.
Five steps to choose the router spot before you drill
- Find where the cable will enter the house. The dish spot decides it: the mount guide helps you pick one.
- Measure the cable route from that entry to a central room, along the path the cable will really take.
- Check the candidate room’s temperature through the year. If it drops below 32 °F or climbs above 86 °F, rule it out; a cheap thermometer left there for a week in the worst season tells you.
- Pick a hard, flat surface at least halfway up the wall, in the open, away from microwaves, refrigerators, metal, concrete and brick.
- Leave open air around the power supply, and plan a mesh router or an Ethernet run for any floor the router can’t reach.
Questions this page answers
Can I put my Starlink router in the attic?
Not in an unconditioned attic. Starlink's weather article lists 32 °F to 86 °F for the router and power supply indoors, attics often run hotter than that in summer, and a router up there reaches the rooms below poorly.
Can the Starlink router be in the garage?
Only if the garage stays within Starlink's indoor range all year and the power supply has room to cool. Starlink says the power supply shuts itself off if it overheats, which drops the connection.
Will a Starlink router work in the basement?
It will work, but Wi-Fi upstairs is often weak, because the signal has to pass through the floor and Starlink advises keeping the router away from concrete and brick. A Starlink mesh router or an Ethernet run upstairs fixes that.
Where should the Starlink router go instead?
A central spot in the living space, on a hard flat surface at least halfway up the room, in the open rather than in a cabinet or closet. If the cable comes in far from there, a mesh router or an Ethernet run carries the signal the rest of the way.
Is the Starlink router waterproof?
The Router Mini isn't: Starlink says it's for indoor use only and not to place it outside. Router 3 carries an IP56 rating but is still listed for indoor use.
