The short answer
Not reliably. Starlink’s requirement is that the dish has “a clear view of the sky”, and its guides list a roof among the objects that “will cause service interruptions”. Indoors, the dish is under a roof and behind walls. Through a window you may get a weak, patchy connection, and coated or tinted glass can block it entirely. Put the dish outside and keep the router indoors.
What Starlink says about indoor use
The Starlink install guides we have checked don’t address indoor or through-window use directly, and we have not found an official statement on it. What the install guides do say is that the dish “needs a clear view of the sky so it can stay connected with satellites as they move overhead”, and that objects “such as a tree branch, pole, or roof, will cause service interruptions.”
The hardware is split the same way. The dishes are built for outdoors, rated IP67 or higher (sealed against dust and water). The routers are the indoor part: Starlink describes Router 3 as “configured for indoor use”, and the Router Mini as indoor only.
Can Starlink work indoors?
Under a roof, not in any useful way. Concrete slabs, roofing sheets and stone-coated tiles sit between the dish and the satellites. Metal roofing reflects the signal, and reinforced concrete absorbs most of it. Even where some signal gets through, the dish is built to watch a 110° cone of sky (Standard and Mini), and a room gives it none of that. Expect the app to report heavy obstruction, long drops or no connection at all.
Will Starlink work through a window?
Sometimes, poorly. Four things work against it:
- Coated glass. Reflective “mirror” glass, energy-saving low-E glass and tinted film with metal in it all carry thin metallic layers that can weaken or block the signal. Reflective glass is common on office buildings.
- A narrow view. A window shows only a slice of sky on one side of the building; the building blocks the rest. The obstruction map will show most of the sky as blocked.
- Dirt and rain on the glass weaken whatever does get through.
- Heat. A dish in full sun behind glass gets hot. Starlink rates the Standard and Mini dishes to work up to 50°C, and the Mini has been reported to overheat in direct summer sun.
Clear, uncoated glass may let a usable signal through, but expect drops and slower speeds. Our guide to Starlink obstructions explains how to read the map.
Can the Starlink Mini work indoors or through a window?
The Mini is small enough to prop in a window, which is why people ask. It needs the same clear view of the sky as the Standard dish and has the same 110° field of view, so the same limits apply. Behind clear glass a Mini may connect, but poorly and with interruptions: enough for messages in a hotel room, not for a day of video calls. The Mini is also the router, so if it sits outside, its Wi-Fi (rated for up to about 112 m²) has to come back in through your walls. Our Starlink Mini guide covers where it works best.
Temporary use versus a permanent set-up
For a night away, a short site visit or a test before you buy a mount, put the dish just outside: on a balcony or an outside window ledge, with the cable run through the window without trapping it in the frame. Never leave it loose on a ledge above people, a walkway or a car park. Run the obstruction tool first. For anything you rely on every day, mount the dish outdoors properly:
- Balcony. Use the kickstand, or the Mini’s flat mount, on an open balcony with a clear view upwards. Tie it down: Starlink says tethering “should be used in all cases”.
- Outside wall. Starlink’s wall mounts fix to an exterior wall near the top. A dish just outside the window sees far more sky than one behind the glass.
- Short pole. A pole at the roof edge or parapet lifts the dish above the roof line. Starlink’s pipe adapter is for metal pipes only, not PVC.

Where the router can go indoors
The router belongs inside, and that is where you have the most choice. Put it central and raised, away from concrete walls and large mirrors, which is the same advice Starlink gives for placing mesh routers. On a Standard kit the dish cable runs from outside to the router (or, on the Standard 4 kit, to the power supply); it is 15 m as standard, with a 45 m option, so plan the route before drilling. With a Mini mounted outside, the Mini Starlink Ethernet cable can feed a Starlink router indoors, or a Router Mini can join it as a mesh node. For large homes, our Wi-Fi and networking guide covers mesh nodes and access points.
When to get help
If there is no spot outside you can reach safely, or the cable needs to go neatly through a wall, our Starlink installation service mounts the dish outdoors and puts the router where your Wi-Fi needs it. See how Starlink is installed in Nigeria for what’s involved. If you are already set up and it keeps dropping, our support team can help, and our troubleshooting guide lists the app messages.

Starlink indoors FAQs
Can I put the Starlink dish in my roof space or ceiling?
No. The roof is between the dish and the sky, and Starlink lists a roof among the objects that cause service interruptions.
Does tinted glass block Starlink?
Tint with metal in it, reflective glass and low-E glass can weaken or block the signal. Plain clear glass is less of a problem, but still poor.
Can Starlink be used indoors with the dish outside?
Yes, and that is the normal set-up: the dish outdoors on a mount, the cable through the wall, and the router and all your devices inside.
Will the Starlink Mini work on a window sill?
On the inside, poorly at best. On an outside ledge with a clear view up, and tied down, it can work well for short stays.
