Ensure your laptop is within range of an active wireless signal and that the router you want to connect to is configured properly. Consult your router's user guide for instructions on how to do this. If you're using your Dell Inspiron 1545 for the first time, you'll need to go through the Windows setup process before connecting to the Internet. The Inspiron 1545 came preconfigured with Windows Vista, but your computer may have a different operating system if you've picked up a refurbished model.
Press the "Wireless" key in the top left-hand corner of your keyboard to activate all your computer's wireless connections, including Wi-Fi and Bluetooth. A confirmation of your wireless configuration will appear on your screen. Use the "Wireless" key to disable your laptop's wireless radios when you need to shut them down quickly, such as when preparing for takeoff on a flight.
Toggle your wireless adapter to "On" in your computer's Control Panel if you have any problems. If you're using Vista, go to "Control Panel" from your "Start" button and select "Manage Network Connections" from the "Network and Sharing Centre." Right-click your wireless adapter and select "Enable" from the context menu.
Tips and warnings
- To connect to the Internet on your PC for the first time once you've enabled your wireless adapter, open your "Start" menu, click" "Connect to" and follow the onscreen instructions to get online. If you need to enter a network security passcode, you'll be prompted to do so during the setup process. This is the passcode you set when you first installed the router -- if you didn't change from the default passcode, you'll usually find it on a label stuck to the underside of the router.
- Move your computer nearer to your router if you have problems getting a signal. If you're attempting to connect from a location some way away from your router, you may need a wireless repeater to boost your signal.
