Did you know most home wireless networks are NOT secure?

"But I have a firewall so I'm safe aren't I?"

Having a firewall will normally stop unauthorised access to your network or PC from somewhere else on the internet. However, having a badly configured wireless network means somebody may already be ON YOUR NETWORK, without even having to come past the firewall.

There IS Good News However...

Your access point has a lock. Your wireless network devices have a key. Setting up both so that they match enables your access but stops others without the key accessing your system. Adding password protection to your shared network devices helps even more.
