HP Officejet 7500A E910 User Manual

							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 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 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 printers 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.
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 access 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

Guidelines for ensuring wireless network security
This section contains the following topics:
•
To add hardware addresses to a WAP
•
Other guidelines
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 printers MAC address must be added to the WAPs list
of accepted MAC addresses.
1.Print the network configuration page. For information on the network configuration page, see
Understand the network configuration page.
2.Open the WAPs configuration utility, and add the printers 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 configuration 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 partys wireless network, turn off the setting to
automatically connect to non-preferred networks. This is disabled by default in Windows XP. Appendix D
228 Network setup
 
						

							Guidelines for reducing interference on a wireless network
The following tips will help reduce the chances for interference in a wireless network:
• Keep the wireless devices away from large metal objects, such as filing cabinets, and other
electromagnetic 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.
