Quick Answer / Summary: The Starlink Mini features a native Gigabit (10/100/1000BASE-T) RJ45 Ethernet port built directly into the rear casing alongside the DC power jack. Protected by a removable IP67 waterproof rubber grommet, it allows users to connect hardwired desktop computers, network switches, or third-party enterprise firewalls without purchasing proprietary adapters.
When SpaceX launched the Gen 2 rectangular dish, users were frustrated by the omission of a physical Ethernet port, requiring an awkward external dongle. The Starlink Mini corrects this design flaw by integrating a native, ruggedized Gigabit RJ45 Ethernet port directly into the back of the dish.
Physical Port Engineering: Standard RJ45 with IP67 Weather Sealing
Unlike the proprietary SPX push-in connectors of Gen 2, the Starlink Mini uses standard 8P8C (RJ45) modular jacks compliant with TIA/EIA-568.2-D. The included Starlink Ethernet cable features a molded, ribbed silicone gasket that presses into the recessed port cavity, creating a watertight IP67 seal preventing moisture ingress during heavy storms.
Connecting Third-Party Enterprise Routers (Bypass Mode)
For users deploying advanced networking hardware (such as Peplink Balance mobile routers, Ubiquiti UniFi gateways, or GL.iNet travel routers), the Mini’s internal Wi-Fi router can be switched to ‘Bypass Mode’ via the Starlink app. This disables internal NAT and DHCP, turning the Mini into a pure satellite modem that passes WAN IP data directly over the RJ45 port.
Using the Ethernet Port for LAN Expansion
If you keep the Mini’s internal Wi-Fi enabled, the RJ45 port functions as a standard LAN switch port. Connecting an unmanaged 5-port Gigabit switch allows you to plug in hardwired smart TVs, network storage (NAS), and VoIP phones while maintaining active Wi-Fi for mobile devices.
Field Cabling Best Practices: Pure Copper vs. Standard Cables
When fabricating custom-length patch cords to connect the Mini’s Ethernet port to vehicle cabins or outbuildings, always specify 23 AWG or 24 AWG solid pure oxygen-free copper (OFC) with UV-stabilized jackets. Cheap Copper Clad Aluminum (CCA) cables break easily under repeated field flexing and suffer excessive signal attenuation.

Frequently Asked Questions (FAQ)
Q: Can I power the Starlink Mini through its Ethernet port using Power over Ethernet (PoE)?
A: No, the Mini’s built-in RJ45 port is data-only; power must be supplied through the separate DC barrel jack (though third-party passive PoE splitters can combine them).
Q: Can I use standard off-the-shelf CAT6 cables with the Starlink Mini?
A: Yes, any standard RJ45 CAT6 cable will plug in; however, for outdoor installations exposed to rain, use a cable with a compatible waterproof sealing collar.
