How to Set Up a New Router: Step-by-Step Guide

What You Need Before You Start

• Your new router (and its power adapter)
• An Ethernet cable (usually included in the box)
• Access to your ISP's modem or gateway (the device that connects to the wall)
• Your WiFi name and password from your old router (you'll create new ones)

Step-by-Step Router Setup

Step 1 — Unplug Your Old Router

Disconnect the old router's power cable and the Ethernet cable that connects it to your modem or ISP gateway. Leave the modem powered on.

Step 2 — Connect the New Router to Your Modem

Take the Ethernet cable from your modem's LAN port (or the ISP gateway's output port) and plug it into the new router's WAN port — this is usually labeled "Internet" and often a different color than the LAN ports. Then plug in the new router's power adapter and turn it on.

Step 3 — Connect to the Router

Wait 60–90 seconds for the router to boot. Connect to its default WiFi network — the name and password are printed on a label on the bottom or back of the router. Or connect via Ethernet cable from your computer to one of the router's LAN ports.

Step 4 — Access the Router Admin Panel

Open a browser and navigate to the router's admin page. Common addresses:

Step 5 — Run the Setup Wizard

Most routers launch a setup wizard on first login. This will guide you through: setting your WiFi name (SSID) and password, changing the admin password, and configuring basic settings. Follow the wizard — it's designed for first-time setup.

Step 6 — Configure Your WiFi Settings

Recommendations for initial setup:

• WiFi password: Use WPA3 if available, WPA2 otherwise. Minimum 12 characters with letters, numbers, and symbols.
• Admin password: Different from your WiFi password. Write it down and store it somewhere safe.
• 2.4 GHz and 5 GHz SSIDs: You can give them the same name (band steering) or different names (manual control). Same name is simpler for most users.
• WiFi channel: Set to "Auto" initially — the router will select the least congested channel. See our guide on choosing the best WiFi channel if you want to optimize later.

Step 7 — Test Your Connection

Connect a device to your new WiFi network and run a speed test. Compare the result to your plan's advertised speed. If it's within 10–15% via Ethernet, your setup is correct. If it's significantly lower, check that the cable between the modem and router is firmly connected and that the router's WAN port light is active.

Security Hardening After Setup

Once basic setup is complete, spend 5 minutes on these security steps:

1. Disable WPS (WiFi Protected Setup) — see our guide on why WPS is a security risk.
2. Enable automatic firmware updates if available, or note to check for updates every few months.
3. Disable remote management (the ability to access your router admin panel from outside your network) unless you specifically need it.
4. Set up a guest network for visitors and IoT devices — see our guest network setup guide.
