2 Network setup

This section describes how to connect the HP All-in-One to a network and how to view and manage network settings.

For optimal performance and security in your wireless network, HP recommends you use a wireless router or access point (802.11) to connect the HP All-in-One and the other network elements. When network elements are connected through a wireless router or access point, this is called an infrastructure network.

If you connect the HP All-in-One directly to a wireless-capable computer, without using a wireless router or access point, this is known as an ad hoc network. You might only be able to connect to one wireless device at a time with an ad hoc connection.

The advantages of a wireless infrastructure network as compared to an ad hoc network include:

•Advanced network security

•Enhanced reliability

•Network flexibility

•Better performance, especially with 802.11 g mode

If you want to:

Connect to a wireless network with a wireless router (infrastructure).

Connect directly to a wireless-capable computer without a wireless router (ad-hoc).

Add connections to more computers on the network.

Change the HP All-in-One from a USB connection to a network connection.

NOTE: Use the instructions in this section if you first installed the HP All-in-One with a USB connection, and you now want to change to a wireless network connection.
