Any computer with a Wi-Fi adapter can connect to nearby wireless networks, provided you have the network password. The process is essentially the same in both Windows 7 and Windows 8.1.
Before using any network, it's important to know how secure it is. If you are setting up your own network, always use WPA-2 security with a strong password. WEP is considered very poor security. Your data may be at risk if connected to a WEP network, or any network that doesn't require a password.
Connect to a Wi-Fi Network
Step 1
Click the **Wireless Network" icon in the notification area of the desktop. If Wi-Fi is on and connected to any network, the icon resembles a staircase. If it's off, it displays an "X."
Step 2
Click the Wireless On/Off toggle to turn Wi-Fi on. Wait a few seconds for a list of nearby networks to appear. If you don't see any networks, make sure your Wi-Fi router is on and that your computer is in the same room.
Step 3
Click the Connect Automatically check box so that your computer will connect to this network whenever it's in range. Click the Connect button to join the network.
Step 4
Enter the Wi-Fi security key when prompted and click Next. Security keys are case-sensitive. If you don't remember the security key and this is your own network, look at the documentation that came with the router. Often, the security key is on a sticker under the router.
Step 5
Click Yes on a Windows 8.1 computer if you want to automatically connect to other computers or devices on the same network, like a network printer or a smart TV. You should use this option only if you're at home or at work. If you're in a coffee shop or other public place, click No.
