A lot of people who have successfully put in a Wi-Fi network neglect to optimize the way files are shared between computers in a home or workgroup. You can choose ways to organize shared files, and ensure that files are shared securely or not visible to other users on your Wi-Fi network very easily.
If you have Windows XP, follow the simple steps from Microsoft in the following link to configure Simple File Sharing (a module) in XP. Simple File Sharing will let you set permissions for various devices and users on your network. If you have a Mac or Vista, there are ways to optimize your setup as well.
On a Mac, all you need to do is put files you want to share in your Public folder, then go to System Preferences, pick Sharing, and select Personal File Sharing. In Windows Vista, you just use the OS’s Network and Sharing Center to optimize file sharing. Right-click on the network status icon in your system tray.
While you’re at it optimizing file sharing for your Wi-Fi network, you may as well check if the placement of your router and access points is giving you the best performance you can get. This is one of the most common ways that people end up living with less than ideal performance on their home Wi-Fi networks, and one of the easiest wireless problems to fix. See my previous post for how to go about placing your gear for best results.
