Guidelines for reducing interference on a wireless network

Guidelines for ensuring wireless network security

Understand 802.11 wireless network settings

Network name (SSID)

By default, the device looks for the wireless network name or SSID named "hpsetup." Your network may have a different SSID.

Communication mode

There are two communication mode options:

Ad hoc: On an ad hoc network, the device is set to ad hoc communication mode and communicates directly with other wireless devices without the use of a WAP. All devices on the ad hoc network must:

Be 802.11 compatible

Have ad hoc as the communication mode

Have the same network name (SSID)

Be on the same subnet and same channel

Have the same 802.11 security settings

Infrastructure (recommended): On an infrastructure network, the device is set to infrastructure communication mode and communicates with other devices on the network, whether the devices are wired or wireless, through a WAP. WAPs commonly act as routers or gateways on small networks.

Security settings

NOTE: For the available settings for the device, see Understand the network configuration page.

Network authentication: The device's factory default setting is 'Open,' which does not require security for authorization or encryption. The other possible values are 'OpenThenShared,' 'Shared,' and 'WPA-PSK' (Wi-Fi®Protected Access Pre- Shared Key).

WPA increases the level of over-the-air data protection and access control on existing and future Wi-Fi networks. It addresses all known weaknesses of WEP, the original native security mechanism in the 802.11 standard.
