Hi Mike
When setting up your wireless network, you should do the following to prevent other wireless users accessing your network:
- Change the default Router password
- Disable SSID broadcast
- Change the default SSID name
- Enable MAC address filtering
- Limit the DHCP addresses to the number of devices you have
- Turn on WEP or WPA encryption if going wireless
I know of a couple of guys at work who have discovered the wireless networks of neighbours who have basically open networks, akin to hanging a network cable outside your window and putting up a sign saying “please connect..”
Cheers
