See Connecting to an existing WLAN on page 16 or Setting up a new WLAN on page 17. ● Wired—You can access the Internet by connecting to a wired network. For information on connecting to a wired network, see Connecting to a wired network on page 19.
NOTE: See Getting to know your computer on page 3 for information on identifying the type and location of the wireless button on your computer. Using the operating system controls To enable or disable a wireless or wired network device: 1. Right-click the Network Connection icon in the notification area, at the far right of the taskbar. 2.
Setting up a new WLAN Required equipment: ● A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased from an Internet service provider (ISP) ● A wireless router (purchased separately) (2) ● The wireless computer (3) The illustration below shows an example of a wireless network installation that is connected to the Internet. NOTE: Some cable modems include a built-in router. Check with your ISP to see if you need a separate router.
NOTE: HP recommends that you select WPA2, which is the most advanced of the three encryption protocols. The use of WEP encryption is not recommended, because it can be overcome with little effort. ● ● Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) use security standards to encrypt and decrypt data transmitted over the network. Both WPA and WPA2 dynamically generate a new key for every packet, and they also generate a different set of keys for each computer on the network.
Connecting to a wired network Connecting to a local area network (LAN) (select models only) Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (purchased separately). If the network cable contains noise suppression circuitry (1), which prevents interference from TV and radio reception, orient the circuitry end of the cable (2) toward the computer. To connect the network cable: 1. Plug the network cable into the network jack (1) on the computer. 2.
