Unable to Connect to the Internet With My Wireless Laptop
Most laptop computers can connect directly to an Internet connection through a wireless signal. However, if your laptop is failing to connect to any Wi-Fi networks you need to troubleshoot the situation. Possible problems include the receiver being turned off and the wrong password being entered into the Wi-Fi network. You can typically correct the issue with a few troubleshooting steps.
Power down the laptop, leave it off for a few moments, then turn the computer back on. Sometimes a computer does not boot correctly, so restarting the system often corrects this problem.
Right-click the wireless icon in the lower right corner of the desktop, then choose "Enable" from the pop-up window. This ensures the wireless receiver is turned on.
Access the wireless networks in the area by right-clicking the wireless icon, then select "Search for available wireless networks." Make sure the network you wish to join is selected, then type in the required password. If the incorrect password is entered, the computer is not going to gain access to the Wi-Fi signal.
Connect the computer to a wired Internet connection, then navigate to the laptop manufacturer's website. Once there select the "Support" option, followed by "Downloads" (sometimes called "Drivers and Downloads"). Choose the laptop computer you are using and the operating system installed, then select the driver listing next to the wireless Internet connection option. This downloads the latest Wi-Fi receiver driver to your computer. If the driver is not up-to-date, or if it has been removed from the computer, the system is not going to connect to the wireless signal. Once the file has finished downloading, double-click the file, follow the prompts of the installation wizard and select "Install" to install the drivers onto the computer.
