Wireless Internet has become increasingly popular in recent years, as it allows for Internet access without having to physically connect anything to your computer. If your computer is capable of using wireless Internet, and if your computer is within the broadcast range of at least one working wireless network, you should be able to browse the Internet. If you are not able to browse the Internet on a wireless network, a few simple troubleshooting steps can narrow down the issue and assist in getting you online.

Verify your computer's ability to connect wirelessly. To successfully connect to a wireless network, your computer must be installed with an internal or external wireless adaptor, and that adaptor must have the most up-to-date software drivers installed. To determine if your wireless card needs a driver update, check your computer's update manager or contact the customer support at the manufacturer of your computer.
Reset your home network. If you use a wireless network at home, the most common remedy for not being able to connect to a wireless network is to simply reset your modem and router (if you are connecting to a wireless network away from home, you can disregard this step). To reset your home network, simply unplug the power cords of both the modem and router and leave them unplugged for a full 30 seconds If you use a modem/router combination, simply unplug its power cord. After plugging them back in, restart your computer and attempt to connect to the wireless network again. If your computer still is not able to connect to a home wireless network but is able to connect to other wireless networks, contact the technical support department of either your Internet service provider (ISP) or your router manufacturer and have them troubleshoot your home network. If your computer cannot connect to any wireless network, there may be a technical issue with your computer.
Have your computer looked at. If you take your computer to an electronics or computer repair store, often they can try and connect to an in-house wireless network to see if the problem lies with your computer or with the wireless network you are attempting to connect to. These stores can also replace your wireless card if that would remedy the issue. Alternatively, you can contact the manufacturer of your computer and have technical support troubleshoot your wireless card.
