Simplify Your Starlink Mini Setup with a PoE Mod

If you’ve mounted a Starlink Mini on your roof or RV, you might be dealing with weak Wi-Fi signal indoors. The Mini’s built-in router often isn’t powerful enough to send strong signals into your living space.

Why Add PoE?

A smart fix is to use an external router placed closer to your devices—this boosts coverage and performance. But the Starlink Mini doesn’t support power over Ethernet (PoE), meaning you'd usually have to run both a power cable and an Ethernet cable.

With a simple PoE modification, you only need one cable—a much cleaner and more efficient setup.

How the PoE Mod Works

This involves a few components:

• PoE injector & splitter (like the EDUP kit): Supplies both power and data over one Ethernet cable. The splitter at the dish separates power to the DC input and data to the Ethernet port.

• External router: Installed near your devices—inside your home or RV—for stronger Wi-Fi.

• Tools and cable: Basic tools for wiring and a good-quality outdoor-rated CAT6 cable (up to ~150 ft recommended).

You’ll wire the injector to a power source, run one Ethernet cable to the splitter, and connect power/data to the Mini with the split outputs. The same cable also connects to your external router, creating an insulated, all-in-one solution.

Setup Highlights

• Cleaner installation: One cable instead of two, giving a tidier look and fewer entry points.

• Better indoor Wi-Fi: Your external router delivers full-speed internet where you really need it.

• Bypass mode supported: Disable the Mini’s internal Wi-Fi in the app to let your external router fully manage your network.

• Fast performance: One user went from sub-30 Mbps Wi-Fi to over 140 Mbps using this wired setup.

Bottom Line

This DIY PoE modification turns a Starlink Mini into a seamless, high-performance setup—especially useful for roof or RV installations. With minimal tools and components, you get reliable Wi-Fi indoors and a neater installation overall.
