Secure your network You don't go to sleep at night with your doors unlocked, so don't venture into cyberspace without security. Depending on your wireless router security level, consider using one or more of the following security measures: ■ Enable encryption on your router. If you have not already enabled security encryption, follow the router manufacturer's instructions to set the highest level of security provided by the router. WEP and WPA are security encryption protocols. ■ Change the default SSID (your network name) on the wireless router and on all computers in the network. The SSID should be a unique name that will not be easily associated with you. Important: The same SSID must be specified on the router and on the computer(s), or the devices cannot communicate. 1 To change the SSID on your router, refer to the router instructions. 2 To change the SSID on each computer in your network: a Select Start > Control Panel > Network and Internet Connection > Network Connections. b Right-click Wireless Network Connection and select Properties. (The Properties window is displayed.) c Select the Wireless Networks tab. d Change the SSID. DID YOU KNOW... Chance of someone piggybacking on your wireless account: 1 in 10,000 DID YOU KNOW...

Setting the highest level of security on your browser is the safest way to browse, but it will limit your ability to access and receive some types of information. Note: There are additional means of securing your wireless network. Refer to your router instructions for more information.
