The Starlink Mini's built-in Wi-Fi is enough for most people, but there are good reasons to go wired. A van or cabin with its own router, a desk far from the dish, a security system, or a work laptop that needs a stable connection all benefit from Ethernet. The Mini has a sealed Ethernet port, which surprises some owners because it is covered by a plug out of the box. This guide covers how to use it, the cable options, setting up your own router and keeping the connection weatherproof.
Why go wired?
- Distance. The dish sits outside; Wi-Fi from a roof through a metal van body is weak inside.
- Your own router. A van or RV router with better antennas, mesh or a cellular backup.
- Stability. Wired links avoid Wi-Fi interference in busy campgrounds.
- Devices without Wi-Fi. Some cameras, controllers and desktop computers.
The Mini's Ethernet port
Starlink's installation guide shows a single Ethernet port on the Mini, closed by a plug that keeps it sealed. You remove the plug and connect a Mini Ethernet cable. Starlink notes that an ordinary RJ45 cable will not keep the port watertight, so for outdoor use you need a sealed cable or adapter.
Cable options
| Option | Sealing | Best for |
|---|---|---|
| Starlink Mini Ethernet cable | Sealed at the dish | Outdoor, simple install |
| Third-party sealed RJ45 adapter | Varies by maker | Using a standard patch cable |
| Combined power and Ethernet cable | Gaskets at both ports | One run from dish to inside |
| Plain RJ45 cable | Not sealed | Indoor, dry use only |
| Product | Key specs | Link |
|---|---|---|
| FlenKn 2-in-1 Starlink Mini Power + Ethernet Cable, 16.5 ft (TPWLXL01) | One 16.5 ft / 5 m run carrying DC power and Cat 6 RJ45 Ethernet; 10A rated; 1000 Mbps; IPX4 gaskets on both ports; includes DC to USB-C adapter with PD chip (20V, up to 100W; listing says the PD source must supply at least 20V/3.25A); also sold in 33 ft | Check price on Amazon (opens in a new tab) |
| STARGEAR Starlink Mini Magnetic Mount, 200 lb, lockable | 4 magnetic bases, 66 mm, 200 lb total pull; listing says supports up to 80 MPH; die-cast aluminum; adjustable magnet holes for ribbed or smooth roofs; 8 degree tilt; locking screws for power and ethernet cables with anti-theft screwdriver | Check price on Amazon (opens in a new tab) |

FlenKn 2-in-1 Starlink Mini Power + Ethernet Cable, 16.5 ft (TPWLXL01)
One 16.5 ft / 5 m run carrying DC power and Cat 6 RJ45 Ethernet; 10A rated; 1000 Mbps; IPX4 gaskets on both ports; includes DC to USB-C adapter with PD chip (20V, up to 100W; listing says the PD source must supply at least 20V/3.25A); also sold in 33 ft
Pros
- Power and wired Ethernet in one cable
- Works with the original Mini power supply
- Includes a USB-C PD adapter
Cons
- IPX4 only, so keep the connectors out of standing water
- Listing's 65W minimum conflicts with Starlink's own 100W USB-C advice; plan for 100W
FlenKn's cable carries DC power and a Cat6 line in one 16.5-foot run, with IPX4 gaskets on both ports. That simplifies a roof-to-cabin install to one cable and one entry hole. IPX4 covers splashes, not immersion, so keep connectors out of pooling water.
STARGEAR Starlink Mini Magnetic Mount, 200 lb, lockable
4 magnetic bases, 66 mm, 200 lb total pull; listing says supports up to 80 MPH; die-cast aluminum; adjustable magnet holes for ribbed or smooth roofs; 8 degree tilt; locking screws for power and ethernet cables with anti-theft screwdriver
Pros
- Locks the cable and dish against theft or pull-out
- Adjustable bases suit ribbed roofs
- Maker sells a steel plate for glass or aluminum roofs
Cons
- Lower speed rating than Vehiker's claim
- Glass or aluminum roofs need the separate plate
This magnetic mount includes locking screws for the power and Ethernet cables, which stops a heavy Ethernet run tugging the plug loose.
Setting up your own router
- Connect the Mini's Ethernet to the WAN or internet port on your router.
- Set the router's WAN to automatic (DHCP).
- Decide whether to keep the Mini's Wi-Fi on. In the Starlink app, Bypass Mode turns off the Mini's own Wi-Fi so your router handles everything. Starlink notes some app features rely on the Mini's router, so read the in-app explanation.
- Connect your devices to your router's network.
- Check the connection in the Starlink app, which can still see the dish through your router in most setups.
Laptops and switches
You can plug a laptop directly into the Mini's Ethernet. For several wired devices, add a small switch. If your laptop has only USB-C, a USB-C Ethernet adapter on the laptop side is fine; that adapter is separate from the dish's sealed connector.
Power is still separate
The Mini's Ethernet does not supply or accept power. Keep its DC cable connected. That means two cables run to the dish, unless you use a combined one. For long runs, power is the limiting factor: Ethernet itself allows up to 100m on Cat5e and Cat6, but low-voltage DC drops quickly. Our cable length guide explains how far each can go.
Weatherproofing
- Keep the original port plug in a safe place, and refit it whenever you are not using Ethernet outdoors.
- Route the cable with a drip loop so water runs away from the connector.
- Do not let connectors sit in puddles or snow.
- Check gaskets for cracks each season.
Vans and RVs
A van router mounted inside, with Ethernet from the roof dish, gives strong Wi-Fi throughout the living space. It also allows a cellular router to fail over when Starlink is blocked by trees. See our campervan setup guide for the full layout and our cable entry guide for getting both cables inside.
Troubleshooting a wired link
If a wired device shows no connection, start simple. Confirm the Mini is online in the app over Wi-Fi first. Reseat the Ethernet cable at both ends and look for the link light on your router or laptop port. Try a different patch cable on the indoor side. If your router shows a WAN address but no internet, restart the router after the Mini is fully online, since some routers give up if they boot first. If you enabled Bypass Mode and lose access to the Starlink app, reconnect through your own router's network; most of the app still works there.
Slow speeds over Ethernet but fine over Wi-Fi usually mean a damaged cable or a port that has fallen back to 100Mbps. Check the link speed on your device and replace the cable if it is not gigabit.
Security on a wired network
A wired link is only as secure as the network behind it. Change your router's default admin password, keep its firmware updated, and use a strong Wi-Fi password. In a campground, do not leave an open guest network running from your van.
FAQ
Does the Starlink Mini have an Ethernet port?
Yes. It has a single sealed Ethernet port behind a plug.
Can I use a normal Ethernet cable?
Indoors, yes. Outdoors, use a sealed cable or adapter to keep the port watertight.
Does Ethernet power the Mini?
No. Keep the DC power cable connected.
Do I need Bypass Mode?
Only if you want your own router to handle all Wi-Fi. It is optional.
How long can the Ethernet cable be?
Up to 100m by the Ethernet standard. Power cable length is the tighter limit.
