More information about using a WLAN is available through your ISP and the user guide included with
your wireless router and other WLAN equipment.
For a list of public WLANs near you, contact your ISP or search the Web. Web sites that list public
WLANs include Cisco Internet Mobile Office Wireless Locations, Hotspotlist, and Geektools. Check
with each public WLAN location for cost and connection requirements.
Using wireless security features
When you set up a WLAN or access an existing WLAN, always enable security features to protect
your network from unauthorized access. The most common security levels are Wi-Fi Protected
Access (WPA)-Personal and Wired Equivalent Privacy (WEP).
When setting up a network, use one or more of the following security measures:
● Enable WPA-Personal or WEP security encryption on the router.
● Change the default network name (SSID) and password.
●
Use a firewall.
● Set security on your Web browser.

2. Click Hewlett-Packard, and then click HP System Information.
3. Click System Information to launch the Microsoft® System Information utility.
