The key will have a logo of an antenna with radio waves coming out of each side, or it may have an image of an airplane to signify Airplane Mode. Tap this key to toggle your wireless adapter on and off. You may need to press the " Fn " key in conjunction with the Wi-Fi key.
  2. If your keyboard doesn't have a Wi-Fi key, you can look for the Wi-Fi icon in the taskbar. If there is no wireless connection, it will be an icon that resembles a globe.

  1. This tool lists all of the components installed on your computer. Hardware on your computer is controlled by software called "drivers". Reinstalling your wireless adapter's driver is the quickest way to troubleshoot it when it won't turn on. Windows will handle the heavy lifting automatically. Use the following steps to open Device Manager:
    • Click the Windows Start menu.
    • Type Device Manager .
    • Click Device Manager in the Start menu.
  2. This expands the section and lists all your network adapters. One of them is your wireless internet adapter.
  3. This displays a pop-up menu. The option to uninstall the driver is in the pop-up menu.
  4. You'll need a network connection in order for Windows to automatically install the correct driver. Use an Ethernet cable and attach your laptop to one of your router's LAN ports.
  5. Once you're connected to your router via Ethernet, reboot your computer.
  6. Windows should detect your driver-less adapter automatically once you log in. It will prompt you to let it find and install the proper driver. If you're connected to your router via Ethernet, Windows will be able to check online for the latest version of the driver. Windows will download and install them automatically.
  7. After the driver installation (which may take several minutes), your network adapter should turn back on. If your adapter has an indicator light, you should notice it change from orange to blue. [2]
    • Click the Network icon in the system tray and select your wireless network. You'll need to enter the password if the network is secured.

Performing a System Restore

  1. If your internet connection was working a few days ago but isn't anymore, you may be able to fix the problem by performing a system restore. This will roll back your computer's settings to the date that you select. Any changes made to the system since the date will be undone. This means that programs that you've installed since the selected date will be removed, and settings will be reverted. A system restore will not affect your personal files.
  2. It's the icon with the Windows logo in the lower-right corner. Click the icon to display the Windows Start menu.
  3. This displays the option to create and manage system restore points on your computer.
  4. This opens the Protection tab in the System Properties menu.
  5. It's the first button below "System Restore" header on the right.
  6. This selects the restore point Windows created last time there were changes to your system.
    • Alternatively, if you have created a restore point, you can select "Choose a different restore point" to see a list of all the restore points. Click the restore point you made and click Next .
    • Click Scan for affected apps to see if what apps will be removed by reverting back to this restore point. Your documents and data will remain unaffected.
  7. This confirms that you want to revert your system back to the restore point and begins the restore process. Your computer may restart several times during this process. [3]

    Turn your router off for five seconds, then restart your phone. Or, check your settings -- you may have turned an option controlling it off.
