Adding Wi-Fi to Your Start9 Router

Start9 · 8 October 2026

If you bought a Start9 router in the United States, it arrived as a wired router, and Wi-Fi comes from a small module you install yourself. This guide walks you through installing it safely. It takes about fifteen minutes.

Why Wi-Fi ships separately in the US

In March 2026 the FCC added routers produced outside the United States to its Covered List. Our router was designed and ordered before that change, so in the US we sell it as a wired router, a small computer running StartWRT, with an FCC-certified Wi-Fi module available separately. Outside the US, routers ship with the module already installed.

Which Wi-Fi modules work

The router takes a mini PCIe Wi-Fi module with a MediaTek MT7916 chipset, such as the AsiaRF AW7916-NPD we sell. StartWRT broadcasts on 2.4 GHz and 5 GHz at the same time.

In the US, choose a module with an FCC ID printed on it. The AW7916-NPD's is TKZAW7916-NPD.

Before you start

You need: the router, the Wi-Fi module, the small screwdriver that came in the router's box, and a clean, dry, well-lit table. A small bowl for the screws helps.

Static electricity can destroy the module. Work on a hard table, not on carpet or a bed. Before you take the module out of its bag, touch a bare metal object such as a metal table leg or a radiator, and touch it again if you get up and walk around. Hold the module by its edges, and do not touch the gold contacts or the chips.

The antenna connectors are tiny and delicate. They snap on by pressing straight down and come off by lifting straight up. Never pull on a wire to remove its connector, never press at an angle, and never force one. If it doesn't click on, lift it off and line it up again.

Installing the module, step by step

1. Unplug everything

Disconnect the power cable and every Ethernet and USB cable from the router.

2. Remove the four screws on the front

Use the screwdriver from the box, and put the screws in your bowl.

3. Slide the top off

The top slides off easily. Inside you will see the empty mini PCIe slot and three antenna wires hanging loose from the antenna mounts.

4. Attach the three antenna wires to the module

This is the fiddliest step, and it is easier with the module in your hand than in the router. Touch bare metal, take the module out of its bag, and hold it by its edges. For each wire, set the connector squarely over one of the module's antenna sockets and press straight down with a fingertip until it clicks. A seated connector sits flat on its socket.

If your module has fewer than three sockets, leave the extra wire unconnected and tuck it away from the board.

5. Insert the module into the slot

Hold the module at a slight angle, with its gold contacts toward the slot, and slide it in until the contacts disappear. Then press the free end down flat against its screw mount. It only fits one way; if it doesn't go in easily, check that the notch in the contacts lines up with the slot.

6. Screw the module down

Use the same screwdriver. Snug is enough; do not overtighten.

7. Check the wires, then close the case

Make sure all three connectors are still seated and no wire sits where the top could pinch it. Slide the top back on and put the four screws back in.

8. Screw on the antennas

Screw an antenna onto each antenna mount, finger-tight.

9. Power on

Reconnect your cables and power. Your Wi-Fi network appears once the router has started. To set it up, see Wi-Fi in the StartWRT documentation.
