If the Internet works on another device, it is safe to assume that the issue is the computer. Verify the Internet connection is working by making sure a different device, like another computer, smartphone, or tablet, can connect to the Internet. If you can connect to your Wi-Fi device, but your Internet is not working, the issue may be your Internet service and not your computer. If you are connecting to a neighbor's router or are entering the wrong security key, the laptop can't connect to the network. If your wireless connections list shows multiple available wireless networks, make sure you are connecting to the right SSID (router name) and have entered the correct security key. Verify the SSID and security key are correct If you see 'Disable,' the network connection is already enabled. In the Network Connections window, if your wireless connection is listed, right-click it and select Enable.
In the Status window, under the Change your network settings section, click the Change adapter options option. In Windows 10, type network status in the search text box next to Start, and press Enter.
In Windows 8, type network connection anywhere on the Start screen and select the View network connections option in the search results.
