How to Set Up a New Router

New router out of the box? It looks intimidating but the setup is a 20-minute job. The modern way is almost always through a phone app. Here's the full walkthrough.

Before you start

• New router (with power adapter and ethernet cable)
• Your existing modem (or combo gateway from your ISP)
• Your phone
• 20 minutes

Step 1: Find a good spot for the router

Wi-Fi degrades through walls, water (fish tanks!), and metal. Best placement:

• Central location in your home, not in a corner
• Elevated (not on the floor)
• Out in the open, not in a cabinet
• Away from microwaves and baby monitors

Step 2: Connect to the modem

1. Unplug your modem from power. Wait 30 seconds.
2. Plug one end of the ethernet cable into your modem's LAN/Ethernet port
3. Plug the other end into your router's WAN or Internet port (often colored differently)
4. Plug modem back into power. Wait 2 minutes for lights to stabilize.
5. Plug router into power. Wait 2 minutes.

Step 3: Download the router app

Modern setup uses the app. Look for the brand on the box:

• TP-Link: TP-Link Tether app
• Netgear Nighthawk: Nighthawk app
• Asus: ASUS Router app
• Eero: eero app
• Google Wifi / Nest Wifi: Google Home app
• Linksys: Linksys app

Step 4: Follow the app's setup

The app walks you through:

1. Create a router admin account (this is for managing the router, not the Wi-Fi password)
2. Connect your phone to the router's default Wi-Fi (printed on the router sticker)
3. The app finds the router automatically
4. Test the internet connection
5. Name your Wi-Fi (the SSID)
6. Set a Wi-Fi password (14+ characters)
7. Wait 1-2 minutes while it applies and restarts

Step 5: Reconnect your devices

Every device will need the new Wi-Fi name and password. Start with your phone (already done), then laptops, smart TVs, speakers, doorbells, etc.

Step 6: Security settings

In the app, go to settings and make sure:

• WPA2 or WPA3 security is enabled (WPA3 is newer, slightly better)
• WPS is disabled (older, less secure)
• Auto-firmware updates are on (keeps the router patched)
• The router admin password is strong (not "admin")

Step 7: Set up a guest network

Most apps let you create a guest network. Separate Wi-Fi for visitors that doesn't expose your main network. Great for sharing without giving out your real password.

What if it won't connect to the internet

• Check the ethernet cable is in the WAN port, not a LAN port
• Power-cycle the modem and router (unplug, wait, plug back in)
• Check if your modem needs a coax cable plugged in (cable internet)
• Call your ISP. They may need to re-register the new router's MAC address
