Wireless About integrated wireless devices Wireless technology transfers data across radio waves instead of wires. Your computer may be equipped with a wireless local area network (WLAN) device. This device connects the computer to wireless local area networks (commonly referred to as Wi-Fi networks, wireless LANs, or WLANs) in corporate offices, your home, and public places such as airports, restaurants, coffee shops, hotels, and universities.
NOTE: The terms wireless router and wireless access point are often used interchangeably. ● A large-scale WLAN, such as a corporate or public WLAN, typically uses wireless access points that can accommodate a large number of computers and accessories and can separate critical network functions.
Use a firewall. ● Set security on your Web browser. For more information about WLAN security, see the HP Web site at (English only). Identifying a WLAN device If you have a problem connecting to a wireless network, confirm that the integrated WLAN device is properly installed on your computer: Select Start >...
Modem and LAN Using a modem The modem must be connected to an analog telephone line using a 6-pin, RJ-11 modem cable (purchased separately).

Plug the modem cable into the RJ-11 telephone wall jack (2). Connecting a country-specific modem cable adapter Telephone jacks vary by country. To use the modem and the modem cable outside the country in which you purchased the computer, you must obtain a country-specific modem cable adapter. To connect the modem to an analog telephone line that does not have an RJ-11 telephone jack, follow these steps: Plug the modem cable into the modem jack (1) on the computer.
Selecting a location setting Viewing the current location selection To view the current location setting for the modem, follow these steps: Select Start > Control Panel. Click Date, Time, Language, and Regional Options. Click Regional and Language Options. Your location is displayed under Location. NOTE: You must commit these changes in order for them to be saved.
