This article explains how to set up a Wi-Fi network using any wireless router and modem.

How to Set Up Your Home Wi-Fi Network

If the wireless router and other devices are capable of Wi-Fi Protected Setup (WPS), you can connect and configure these devices with the push of a button. However, having WPS set up on a router is a security risk, so we recommend disabling WPS.

Here’s how to set up a Wi-Fi router.

Find the best location for the wireless router. The optimal placement is in a central location, free from obstructions that could cause wireless interference.

Don’t place the router close to windows, walls, or the microwave.
Turn off the modem. Power off the cable, fiber, or DSL modem from your internet service provider before connecting your equipment.

Connect the router to the modem. Plug an Ethernet cable (typically provided with the router) into the router WAN port. Then, connect the other end of the Ethernet cable to the modem.

Connect a laptop or computer to the router. Plug one end of another Ethernet cable into the router LAN port (any port will work) and the other end of the Ethernet cable into the Ethernet port of a laptop.

This wiring is temporary; you will remove the cable after setting up the network.

Power up the modem, router, and computer. It’s best if you turn on these devices in the proper order. Turn on the modem first. When the modem lights are all on, turn on the router. When the router is on, turn on the computer.
Go to the management web page for the router. Open a browser and enter the IP address of the router administration page. This information is in the router documentation (it’s usually something like 192.168.1.1). The login information is also in the manual.
Change the default administrator password (and username) for the router. This setting is usually on the router administration page in a tab or section called Administration. Use a strong password that you won’t forget.
Add WPA2 security. This step is essential. Find this setting in the wireless security section of the router administration page. Select which type of encryption to use and enter a passphrase of at least eight characters. The more characters and the more complex the password, the better.

WPA2 is significantly more secure than WEP. Use WPA or mixed mode WPA/WPA2 with older wireless adapters. WPA3 is another option for more recent hardware, but its compatibility is limited.
Change the wireless network name (SSID). To make it easy for you to identify your network, choose a descriptive name for your SSID (Service Set Identifier) in the router administration page’s wireless network information section.
Optional: change the wireless channel. If you’re in an area with other wireless networks, minimize interference by changing the router’s wireless channel to one that other networks aren’t using.

Use a Wi-Fi analyzer app on your smartphone to find an uncrowded channel or use trial and error (try channels 1, 6, or 11, since these channels don’t overlap).
Set up the wireless adapter on the computer. After saving the router’s configuration settings, unplug the cable that connects the computer to the router. Then, plug a USB or PC card wireless adapter into the laptop if it doesn’t have a wireless adapter installed or built-in.

Your computer may automatically install the drivers, or you may have to use the setup CD that came with the adapter.
Connect to the new wireless network. On your computer and other wireless-enabled devices, find the new network you set up and connect to the network.

FAQ

Why is my phone not connecting to Wi-Fi?

If your phone can’t connect to Wi-Fi, make sure Wi-Fi is turned on, turn off Airplane Mode, check the Wi-Fi password, and try disconnecting and reconnecting from the network. If you still can’t connect, check for operating system updates, restart your device, and reset your network settings.
How can I get Wi-Fi at home without cable?

To get Wi-Fi without cable or a phone line, look for an internet service provider (ISP). Compare plans, contact multiple providers, and ask around online.
How do I set up a Wi-Fi extender?

To install a Wi-Fi extender, connect it to your existing router and use it to broadcast a new Wi-Fi network. Place the extender in an area that needs a stronger connection. Larger homes may benefit more from a long-range or mesh router.
