I'm a Technical Support Representative for more than 5 years now and there are a lot of people calling us for help on how to set up their wireless connection. Here I will teach you a step by step procedure on how to set up windows 7 computer to a wireless network. But before everything else, you need to make sure that your wireless adapter is installed and is enabled. Though for most computers, the wireless adapter is on by default, you still need to make sure that if you are using a laptop, your wireless adapter is turned on.
First step is to make sure that you have the wireless network name (SSID) as well as the Wireless Encryption Key (WEP) of the network you want to connect to. For most routers, those information are located at the bottom of the modem (EX: 2WIRE, WESTELL, MOTOROLA)
Second, go to your computer, locate the wireless connection icon in the system tray. It is normally located at the lower right hand corner of your computer, next to the clock. This icon will look like five bars and would show an orange dot on the bars if there is no connection.
Third, click on the wireless connection, it will open up a list of wireless networks available.
Fourth, find the name of your wireless network and select connect button. Make sure that you check the box that says Connect automatically if you plan to use that network in the future.
If your network is a Security-enabled network, you will be asked to type in the network key. If it is not wireless password enabled, it will connect to the network automatically.
If you have entered an incorrect wireless encryption key, it will ask you to type it in again. If you have type in the correct information, you will notice that the wireless connection icon in the taskbar will no longer has the orange dot on the bar.
Finally, pull up internet browser and start surfing the net. It's easy!
