A Starlink dish can be working perfectly while half the house has no usable WiFi. It is easy to blame the dish, but it is a different problem with a different fix.
One message we had this year shows it well. It came from an old house near Henley. Someone sent by Starlink had installed the dish, but the WiFi did not reach round the house because of the thick walls. The satellite link was not the issue. Getting the signal through the building was.
This guide covers why the Starlink router runs out, how to tell whether it is the dish or the WiFi, and the four ways to fix it. If you want it done for you, see our whole home WiFi installation service.
Why the Starlink router runs out
Where the router ends up. The router goes where the cable comes in. With Starlink’s own checkout installation, the router is placed near the cable entry, which is often a utility room, a garage wall or one end of the house. WiFi spreads out from there, so the far end and upstairs get the least.
What the house is made of. Starlink’s support pages say brick, stone and multiple walls reduce coverage. Solid walls in period houses, steel beams in extensions, foil-backed insulation in lofts and new builds, and a garden office down the garden all cut into the signal.
Which router you have. Current UK kits come with one of these, and Starlink quotes a coverage figure for each:
- Router 3 (with the Standard 4 X kit): WiFi 6, tri-band, two Ethernet ports, up to 297 m².
- Router Mini (with the Standard 4 kit): WiFi 6, dual-band, one Ethernet port, up to 204 m².
- Starlink Mini dish: WiFi 5, dual-band, built into the dish, up to 112 m².
Treat those as best-case figures. A typical four bedroom house is well under 297 m², but it is the walls and floors, not the floor area, that stop WiFi.
First, check it is the WiFi and not the dish
- Run a speed test standing next to the Starlink router.
- Run another in the room where it is poor.
- Open the Starlink app and look for outages and obstructions.
If the speed is good by the router and poor elsewhere, it is a WiFi problem and the fixes below apply. If it is poor everywhere, or the app shows regular obstructions, start with the dish position. Our guide to Starlink and trees covers that.
Option 1: move the router
The cheapest fix is often to get the router out of the corner. A new cable route inside the house, or a longer Starlink cable (Starlink sells a 45 m one for the Standard kit), can bring it to a more central spot, up off the floor and out of cupboards. In an ordinary house with plaster walls, that alone can be enough. In a house with thick walls, it rarely is.
Option 2: Starlink mesh nodes
Starlink sells its own mesh nodes, and the Router Mini doubles as one. They suit an ordinary house where the router reaches most rooms but not all. Starlink’s own advice:
- Place each node one or two rooms from the main router, not in the dead zone itself.
- Each node should connect directly to the main router. Chaining nodes, one off another, performs worse.
- Router 3 supports up to three Starlink mesh nodes.
- In very large homes, connect nodes back to the main router with Ethernet, from the router’s LAN port to the node’s WAN port.
Starlink mesh does not work with third-party mesh systems, so you cannot mix a Starlink node with a TP-Link Deco or similar.
Option 3: your own router or mesh, with Starlink in bypass mode
If you already have a good mesh system, or you want features the Starlink router does not have, bypass mode hands the network over to your own equipment. Things to know:
- Bypass mode turns off Starlink’s WiFi completely. Your own router plugs into the Starlink router’s Ethernet port. Older Gen 2 routers have no Ethernet port and need Starlink’s Ethernet adapter.
- With Router 3, the Starlink router stays powered and in line even in bypass mode, so it still needs a home.
- The only way out of bypass mode is a factory reset of the Starlink router, so set up your own system before you switch it on.
- Starlink uses CGNAT for IPv4, so you cannot forward ports over IPv4 for things like a home server, whichever router you use. IPv6 addresses are public, and a public IPv4 address is only available on Priority plans.
Mesh WiFi installation explains how we set up mesh behind Starlink, and is mesh WiFi worth it covers where mesh works well and where it does not.
Option 4: wired access points
For older houses with solid walls, large homes, homes with extensions, and garden offices that need to work properly, wired access points are the most reliable answer. A Cat6 cable runs from the router position to each access point, usually on the ceiling, and each one is powered over the same cable. Wireless mesh nodes have to talk to each other through the same walls that block your devices. Wired access points do not, because each one has its own cable back to the router.
With Starlink, the usual setup is Starlink in bypass mode feeding a router and a PoE switch, then access points where they are needed. You get one network name across the house, the garden office and the patio.
This is the approach we take in houses like the one near Henley, where thick walls defeat both the Starlink router and wireless mesh. Our data cabling service runs the cable, and wired access points vs mesh explains the difference in more detail. For older homes, see period and Victorian property WiFi.
Which option suits your house?
- Small to medium house with plaster walls, one or two weak rooms: move the router, then add one or two Starlink mesh nodes.
- You already own a decent mesh system: use bypass mode and keep it.
- Period house, thick walls, large house or a big extension: wired access points.
- Garden office or outbuilding: a cable through a duct, or a point-to-point wireless bridge where a trench is not practical. See getting internet to a garden office and our garden office WiFi service.
Plug-in extenders are the option we would skip. They repeat a signal that is already weak and often create a second network name that phones and laptops cling to.
Starlink WiFi across Berkshire and Surrey
Many of the homes that need Starlink are also the ones its router struggles with: older farmhouses and cottages, extended houses on large plots, and homes with garden offices. That is true of the villages around Maidenhead, Windsor and Ascot, and across Surrey. We can fit the dish and the indoor network in one visit, or fix the WiFi after someone else has installed the dish.
