HP 640n Print Server manual Network Name Ssid, Refresh, Ad Hoc Network peer-to-peer, Channel

Table 4-3Wireless Station configuration parameters (continued)

Item	Description
Network Name (SSID)	Select a network name that the HP Jetdirect print server connects to from the Existing
	wireless network list, or, provide a network name in the Select Network Name field.
	The network name is also called the service set identifier (SSID) and identifies the
	extended service set (ESS) that is normally associated with larger infrastructure mode
	networks. The print server lists the detected SSIDs.
	An empty (or blank) SSID field is accepted, for example, on networks that rely on signal
	strength, encryption and authentication methods to control network access.
	The factory-default SSID configured on the HP Jetdirect print server is “hpsetup”. To
	initially communicate with the print server, your wireless computer's SSID must also be
	“hpsetup”.
	NOTE: The SSID characters are case sensitive. Ensure you use the appropriate
	lowercase or uppercase characters.
Refresh	Click this button to refresh the list of network names detected by the print server.
Ad Hoc Network (peer-to-peer)	Wireless communication topology in which the wireless devices on a network
	communicate directly with each other. Access points are not used. Other terms used for
	ad hoc include independent basic service set (IBSS), and computer-to-computer mode.
	The factory-default mode configured on the HP Jetdirect print server is ad hoc. To
	initially communicate with the print server, your wireless computer must be set up for ad
	hoc.
Channel	(Ad hoc mode only) Identifies the radio frequency that the print server uses to broadcast
	its availability if it fails to associate with the specified ad hoc network on any channel.
	By factory default, channel 11 (2462 MHz) is used. However, channel 10 (2457 MHz) is
	also available.
	The factory-default mode configured on the HP Jetdirect print server is ad hoc. To
	initially communicate with the print server, your wireless computer must be set up for ad
	hoc.
No Security	(No encryption or authentication. Open system.) Your wireless network does not require
	device authentication or security to access the network. However, your network might
	still use WEP encryption keys for data privacy.
WEP — Personal	(Requires a WEP key.) Each device on your wireless network uses a shared encryption
	key (a shared password value) for network access and communications. Each device on
	the network must use the same key. The HP Jetdirect print server supports IEEE 802.11
	wired equivalent privacy (WEP) keys for encrypted network communications. If you
	select WEP encryption, you must configure one or more WEP keys. Provide the
	following if you select WEP:
	● Authentication — (Read only) Set to Auto authentication, which automatically
	selects open or shared. Open system authentication does not require
	authentication for network access. (Your network might use WEP encryption keys
	for data security.) Shared authentication requires that each device be configured
	with the same WEP key for network access.
	● WEP Key — The WEP key format is programmatically determined and validated
	using either alphanumeric ASCII (8-bit) characters or hexadecimal (4-bit) digits.
	● Key Index — Specify the WEP key index position (1, 2, 3, 4) that the print server
	uses for encrypted communications.
