This brings me to the main point of this post: Secure that wireless LAN!
When my iBook booted up, it detected a wireless LAN belonging to one of my neighbors. It is wide open. I was not only able to get an IP and get onto the Internet, I was able to login to his wireless router because it still had the factory default settings.
Tips for securing a wireless network:
- When setting it up, change the default administrative password.
- After you have your clients associated with the access point, disable SSID broadcast.
- Enable WPA or WEP encryption.
- Enable MAC filtering, which limits what wireless cards can associate, using their hardware addresses.
- Disable DHCP and manually configure the IP settings of your wireless clients.
