Set up the printer for wireless communication
You may set up the printer for wireless communication.
NOTE: If you encounter problems, see Solvewirelessproblems.
Make sure the printer is not connected to the network using a network cable.
The sending device must have built-in 802.11 capabilities or an 802.11 wireless card installed.
The printer and the computers that use it must be on the same subnet.
Before installing the HP software, you might want to find out the settings of your network. Obtain
the information from your system administrators, or complete the following tasks:
• Obtain your network's network name or Service Set Identifier (SSID) and communication mode (infrastructure or ad hoc) from the configuration utility for the network's wireless access
point (WAP) or the computer's network card.
• Find out the type of encryption your network uses, such as Wired Equivalent Privacy (WEP).
• Find out the security password or encryption key of the wireless device.

To set up a wireless communication using the Wireless Setup Wizard
The Wireless Setup Wizard provides an easy way to set up and manage a wireless connection
(both infrastructure and ad hoc connections) to your printer. (continued)
Set up the printer for wireless communication 219
 
						

							
NOTE:To connect to an infrastructure network, you must have a wireless network set up
and running.
1. Set up the printer hardware. See the getting started guide or the setup poster that came with
your printer.
2. On the printer control panel, touch right arrow 
, and then select  Network.
3. Touch Wireless , select Wireless Setup Wizard , and then touch OK.
4. Follow the display instructions to complete the setup.
NOTE: If you cannot find the network name (SSID) and WPA key or WEP passphrase,
contact your network administrator or the person who set up the wireless network.
NOTE: If you want to connect the printer using an ad hoc connection, connect your
computer to the network name (SSID) “hpsetup“. (This network name is the default, ad hoc
network created by the printer.) If your printer was previously configured for a different
network, you can restore the network defaults to enable the printer to use “hpsetup“. To
restore network defaults, see 
Resetnetworksettings.
Understand 802.11 wireless network settings
Network name (SSID)
By default, the printer 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 printer is set to ad hoc communication mode and
communicates directly with other wireless devices without the use of a W\
AP.
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 printer 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
• Network authentication:  The printer'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.
Appendix D
220 Network setup 
 
						

							
WPA2 is the second generation of WPA security; it provides enterprise and consumer Wi-Fi
users with a high level of assurance that only authorized users can acce\
ss their wireless
networks.
• Data encryption:

•Wired Equivalent Privacy (WEP) provides security by encrypting data sent over radio
waves from one wireless device to another wireless device. Devices on a WEP-enabled
network use WEP keys to encode data. If your network uses WEP, you must know the
WEP key(s) it uses.
NOTE: Shared WEP key encryption is not supported.

•WPA uses the Temporal Key Integrity Protocol (TKIP) for encryption and employs
802.1X authentication with one of the standard Extensible Authentication Protocol (EAP)
types available today.

• WPA2 provides a new encryption scheme, the Advanced Encryption Standard (AES).
AES is defined in counter cipher-block chaining mode (CCM) and supports the
Independent Basic Service Set (IBSS) to enable security between client workstations
operating in ad hoc mode.
Test the wireless connection
Print the wireless test page for information about the printer's wireles\
s connection. The wireless
test page provides information about the printer's status, MAC address, and IP address. If the
printer is connected to a network, the test page displays details about the network settings.
1.
Touch right arrow 
, and then select  Network.
2. Touch Wireless , and then select  Wireless Network Test .
Change the connection method
If you have installed the HP software and connected your printer using a USB, Ethernet, or
wireless connection, you can change to a different connection any time you want.
NOTE:If you are changing to a wireless connection, make sure that an Ethernet cable has
not been connected to the printer. Connecting an Ethernet cable turns off the printer's
wireless capabilities.
To change the connection method (Windows)
NOTE: If you are changing to a wireless connection, make sure that an Ethernet cable has
not been connected to the printer. Connecting an Ethernet cable turns off the printer's
wireless capabilities.
1. On the computer desktop, click  Start, select  Programs  or All Programs , click HP, select
your printer name, and then click  Connect a New Printer.
2. Follow the onscreen instructions.
To change the connection method (Mac OS X)

3. Double-click HP Setup Assistant , and then follow the onscreen instructions.
Guidelines for ensuring wireless network security
This section contains the following topics:
•

•
Otherguidelines
Set up the printer for wireless communication 221
 
						

							
To add hardware addresses to a WAP
MAC filtering is a security feature in which a WAP is configured with a list of MAC addresses
(also called "hardware addresses") of devices that are allowed to gain access to the network
through the WAP.
If the WAP does not have the hardware address of a device attempting to access the network,
the WAP denies the device access to the network.
If the WAP filters MAC addresses, then the printer's MAC address must be added to the WAP's
list of accepted MAC addresses.
1.Print the network configuration page. For information on the network configuration page, see
Understandthenetworkconfigurationpage.
2. Open the WAP's configuration utility, and add the printer's hardware address to the list of
accepted MAC addresses.
Other guidelines
To keep the wireless network secure, follow these guidelines:
• Use a password with at least 20 random characters. You can use up to 64 characters in
a WPA password.
• Avoid any common words or phrases, easy sequences of characters (such as all 1s), and personally-identifiable information for passwords. Always use random strings composed of
uppercase and lowercase letters, numbers, and if allowed, special characters such as
punctuation.
• Change the password periodically.
• Change the default password provided by the manufacturer for administrator access to the access point or wireless router. Some routers let you change the administrator name as well.
• Turn off administrative access over wireless if possible. If you do this\
, you need to connect to the router with a wired Ethernet connection when you want to make config\
uration changes.
• Turn off remote administrative access over the Internet on your router, if possible. You can use Remote Desktop to make an encrypted connection to a computer running\
 behind your
router and make configuration changes from the local computer you are accessing over the
Internet.
• To avoid accidentally connecting to another party's wireless network, turn off the setting to automatically connect to non-preferred networks. This is disabled by default in Windows XP.
Guidelines for reducing interference on a wireless network
The following tips will help reduce the chances for interference in a wi\
reless network:
• Keep the wireless devices away from large metal objects, such as filing cabinets, and otherelectromagnetic devices, such as microwaves and cordless telephones, as these objects can
disrupt radio signals.
• Keep the wireless devices away from large masonry structures and other building structures as these objects can absorb radio waves and lower signal strength.
• For an infrastructure network, position the WAP in a central location in line \
of sight with the wireless devices on the network.
• Keep all wireless devices on the network within range of one another.
