The firewall built into your router prevents hackers on the Internet from getting access to your PC. But it does nothing to stop people in range of your Wi-Fi signal from getting onto your network--and with the latest high-performance equipment, your Wi-Fi signal could reach clear down the block. Without encryption and other protective measures, anyone can use readily available tools to see all your Wi-Fi traffic.
For extra protection, you should run software firewalls on the individual PCs on your network. Some good options are Zone Labs' ZoneAlarm.
