What You'll Need

To turn your old router into a Wi-Fi repeater, assemble these proven essentials:

• Powerline network adapter (without built-in Wi-Fi)
• Old router (802.11n or 802.11ac for optimal performance)
• Ethernet cable
• Power extension cord (optional)

Gather Your Main Router's Settings

Start by noting your primary router's IP address, broadcast channel, and security type—these ensure compatibility.

1. Open Settings.
2. Select Network and Internet.
3. Click "Network and Sharing Center."
4. Choose "Change adapter settings."

Jot them down without changes, then exit.

Reset Your Old Router

Factory reset erases all prior configurations for a clean start.

1. Power on the router.
2. Insert a paperclip into the reset hole on the back.

3. Hold for 30 seconds.
4. Release; lights will cycle as it restores factory defaults.

Configure the Secondary Router

Prepare it offline:

1. Power off your main router or disconnect a PC from the network.
2. Connect the old router directly to a standalone computer via Ethernet.
3. Access the config page (typically at the default IP like 192.168.1.1).

Copy Settings from the Main Router

Match these for seamless extension:

1. Skip setup wizards.
2. Go to Wi-Fi settings.
3. Enable wireless.
4. Set the network name (SSID) identical to your main router.
5. Pick a different channel to avoid interference.
6. Match the security type precisely.
7. Use the exact same password.

Assign the Old Router a Fixed IP Address

Your repeater needs a static IP outside the main DHCP pool.

1. In LAN settings, assign an IP in the main subnet but beyond DHCP range (e.g., if main uses 192.168.1.2–192.168.1.49, set 192.168.1.50).

2. Disable DHCP.
3. Save and reboot.

Put It All Together

A long Ethernet cable is ideal, but powerline adapters work great over your home's wiring—just ensure both ends share the same circuit breaker.

Test Your Setup

Verify performance:

1. Position halfway between the dead zone and main router.
2. Plug in the powerline adapter.
3. Connect via Ethernet (WAN port on repeater).
4. Power on and connect devices.
5. Run speedtest.net near the main router for baseline.

6. Test near the repeater and compare.
7. Reposition for peak speeds.

This budget-friendly hack delivers robust coverage in hard-to-reach areas. Test it yourself—it's transformed my clients' networks reliably.
