It’s great having a wireless network in your house — but it’s annoying to have to login to the network every time. In this article I’ll show you how to configure Windows Vista so that your computer (laptop or desktop — doesn’t matter) automatically connects to your wireless network.
1. Go to Start->Control Panel->Network and Sharing Center.
2. In the Task area at the left side of the screen, select “Manage wireless networks”
3. You will then see a list of wireless networks to which you have connected in the past. Right-click on the icon for the network in question and select “Properties”
4. In the properties screen that appears, make sure that you check the option: “Connect automatically when this network is in range”.
Note that you may require a restart for this change to take effect, and that if you’ve already entered the network password once, then you should not have to enter it each time you connect.
