Do I need to call my ISP to set up a new router?

No for most ISP connections. For cable internet: connect the modem to the new router's WAN port, reboot both, and the router receives a DHCP IP from the ISP automatically. For DSL or PPPoE connections (often fiber or some DSL setups): enter the PPPoE username and password in the router's WAN settings. You can find these in your ISP account or by calling ISP support.

Should I change the default router WiFi password?

Yes, always. Default WiFi passwords on most routers are printed on a sticker on the device itself — anyone who can see the router can connect to the network. Change the WiFi password and the router admin password during setup. Use a passphrase that is 12+ characters and not based on personal information.

What WiFi channel should I use?

On 2.4GHz: channels 1, 6, and 11 are non-overlapping. Avoid other channel numbers which overlap with neighboring networks. On 5GHz: channels overlap less due to the number available; auto-selection by the router is generally adequate. Enable Auto-Channel Selection in the router admin panel unless you have a specific reason to fix a channel.

How to Set Up a New Router: Step-by-Step Installation and Configuration

Set up a new router by connecting it to the modem, running the setup wizard, changing the default WiFi name and password, and configuring basic security settings. Step-by-step for most major brands.

A new router in its box, and a home full of devices waiting to connect to it. Where do you even start?

Right at the cable between the modem and the router, as it turns out.

The whole process takes 15 to 30 minutes on most consumer routers, from first power-on to a secured WiFi network.

Here is every step, in order, including the settings people skip and regret later.

Step 1: Connect the Hardware

Connect the modem to the router's WAN port using the Ethernet cable. The WAN port is usually labeled "Internet" or "WAN" and is a different color from the LAN ports.
Connect a computer to one of the router's LAN ports with an Ethernet cable.
Power on the modem first. Wait 60 seconds for it to establish the ISP connection.
Power on the router. Wait 2-3 minutes for it to boot.

Step 2: Access the Router Admin Panel

Open a web browser on the connected computer. Navigate to the router's admin panel address — typically 192.168.1.1 or 192.168.0.1. Check the label on the bottom of the router for the exact address and default admin credentials.

Most modern routers include a setup wizard that launches automatically on first login.

Step 3: Run the Setup Wizard

The wizard configures the WAN connection:

Automatic (DHCP): the router detects the connection type and gets an IP from the ISP. Most cable internet connections use this.
PPPoE: requires a username and password from your ISP. Some DSL and fiber connections use this.

Step 4: Change WiFi Settings

Set a new WiFi name (SSID) and password for both 2.4GHz and 5GHz bands. Choose names that do not identify your home or your name. Avoid using the default name (often the router model number).

Step 5: Change the Admin Password

In the admin panel settings, change the router admin password from the default. Store it in a password manager — you will rarely need it but will want it when you do.

Step 6: Update Firmware

Check the router admin panel for firmware updates and install if available. Most modern routers have an automatic firmware update option — enable it.
